    Echo 1 M240 review (kinda)

    Wow thats really weak. The one I have I can't push the mechbox back by hand. Perhaps that is the solution?

    Echo 1 M240 review (kinda)

    I need to see your mechbox "recoiling". Mine, the mechbox is held forward by the faux buffer mechanism which is in the stock and pushes the mechbox foward. There is no "recoil", even with its crazy 500fps spring. Perhaps your recoiling is the same issue I had with the air nozzle and hop unit?

    Echo 1 M240 review (kinda)

    Nice review: In relation to the Inokatsu: There were 2 versions, Alu and Steel. I have the Alu version and wished I had the Steel one, but literally it was the last one for sale I bought it from Hawaii and shipped it to HK where it was then broken into pieces and smuggled into NZ. It clocks in at 8kg unloaded and around 10kg with box mag and rounds. Mine has been a loan "torture" gun for noobs , permanently set at 500fps to teach airsofters appropriate machine gun use. It is quite funny to watch players struggle carry the thing up a 2km hill. No issues after hundreds of thousands of rounds. I have had to change the piston once. Compared with my A&K M60/M249/PKM and G&P M249s, the real strength of the inokatsu is the heavy duty motor and magazine, where debris can get into the mechanism and rounds would still come out. Whereas the M60s or M249s small amount of sand or foliage and would jam the feed mechanism. The weakest part is also the magazine housing, which is cardboard. I constructed a folded polycarb box for field use and over 8 years it has slowly disintegrated. Now I retrofitted an A&K M60 box mag shell so that will last a lot longer. Only thing that really affected this was the hop chamber and air nozzle fitment. Hop chamber is too wide, and the air nozzle it came with was too narrow, which means that the air nozzle would wobble and as soon as the autowinding mag was in tension it would push the nozzle out of airseal alignment with the hop rubber. To fix it I created a thing sleeve that holds the nozzle in place. Other than that its a workhorse.

    WE/Cybergun M1A1 Thompson Submachine Gun

    The rationale behind that is to decrease gas consumption in the blowback cycle. There are two springs which control the amount of gas which result in net rearward movement of the bolt carrier; the main recoil spring, and the nozzle return spring. A quicker rearward movement is a result of lightening of the mail recoils spring and the nozzle return spring. That will result in less effort and gas used to push the bolt carrier rearwards, shutting the gas release valve sooner, using less gas without changing the rate of gas flow in the system. But of course, as an open bolt system, the main recoil spring determines the striker force on the gas release valve, which will affect initial gas release impulse and will affect FPS if trimmed too much. Over lightening of main recoil spring may also result in cycling and reliability issue. Recoil will definitely be harder, and will affect the structure and buffering at the back of the receiver. So it is all a balance.

    WE/Cybergun M1A1 Thompson Submachine Gun

    Yes I did, ROF is lower. When you do it however, you gotta remember that on an open bolt, the impact force releases gas. So if you lighten that too much FPS will be affected. Funny you say that, pretty much Most WEs I would have to do the same sort of fixes to them anyways. It actually makes the WEs more flexible. For example because I need to do that tuning, I can max out gas efficiency, recoil, reliability, and power output where I would have trouble with say a GHK or a Marui. For cheaper, a WE get better performance overall.

    WE/Cybergun M1A1 Thompson Submachine Gun

    Great review! I bought mine recently, and its a fun gun. Shoots at 320-330fps at 27*C, which is bit low for my liking. However gas efficiency is very poor, I get 60 round/cycles out of a full charge. I proceeded to trim the main spring by 30% and stretched + trimmed the nozzle return spring by 40%, got around 80 rounds/cycles per charge, with a noticeable increase in kick. I found that the flute valve was being slammed forward during the cycle and hence resulting in low FPS, using an older and stronger WE flute valve spring to keep the flute valve in place , which increased the FPS. Its now shooting at 430-440fps. Due to the same issues around the hop rubber constriction it is causing a dispersion. The wobbly and misaligned barrel is also causing a number of accuracy issues. So I proceeded to shim the barrel, which brought the rifle back to the correct point of aim. I will be working on the hop rubber later today to get better accuracy. All in all, it does need a heavier barrel and a wood kit, which I will purchase at a later date.

    WE Hi Power MkIII

    Marui's lack of international strategy lost out to WE's strategy a lot time ago. Japanese as a culture are far more conservative than the Chinese, and it translates to their business Acumen. Still, good news around the WE Browning MK3 even though I just bought a GP1935, I will probably pick up the Mk3 at a later date. I have been fitting old AWSS hop ups into the Browning and the Lugers as they don't have hops at all.

    WE AKS-74UN First Impressions (Pic heavy)

    Above is a WE AK PMC, Below is the WELL Uses the traditional AK47 front sight, gas block and furniture. I added the AK47 thread protector (removed the AK74 muzzle break) Side by side comparison Note rear sight block and gas tube, reminiscent of marui AKs. Note triggers, the white putty is reinforcement added by me to strengthen the trigger box. Note the rectangular cut, similar to AEG receiver, but not quite. The pistol grip covers up the hole quite nicely.

    WE AKS-74UN First Impressions (Pic heavy)

    Finally bought a WELL G74D (AK74M), out of curiosity, and in my country its not a regular import. Overall, its not bad. Thought it was gonna be pretty bad, turns out it came with a few good surprises. Following from the previous reviews listed here on the WELL G74A (AKS74U). Picking it up: - It has creaky plastic imitation wood, the whole front section wobbles like a flag pole in the wind. Its a flat black painted, with an aluminium barrel that has been surprisingly well made that has the early heat dissipating threads. - It has a Steel based AEG receiver and barrel trunnion from a CYMA/JG AK. The receiver has a rectangular cut for a motor cage, but it hasn't been cut all the way. However the WELL pistol grip covers the rectangular cut. (More on this later) - Front sight is of a CYMA design - It has a Marui gas tube/ rear sight block, and a marui based stock trunion, with the creaky imitation wood. It can take only take wood kits that fit the original Marui systems. - It had trouble fitting WE AK47 mags without mods. - It was full of grease, which was everywhere. Basically out of the box the barrel was so dirty it was impossible to get consistent accuracy. Spent hours degreasing it afterwards. - The inner barrel is of a VSR cut, but fitted for the WE hop unit. After degreasing the rifle is relatively accurate. - It chronos at around 340-360fps with a 17" inner barrel with a WE AK47 mag @ 18*C, (the gun came with a CO2 Mag). Blowback is similar to a WE, except its slower. - The blowback unit is a low output power unit compared with the WE. That can be easily remedied. After some modifications the blowback unit is now outputting 460fps @ 18*C. - The blowback unit O-ring is not undersized as some reviews have been suggesting. It is actually oversized, no further work is required. - The trigger unit is a replica of the WE, except it looks more heavy duty. - The hammer, semi-auto sear and gas release striker is steel, everything else is zamak. Quite a nice surprise there. However the area on the hammer which engages the auto-sear has a really shallow cut and leads to partial engagement of the auto-sear. This leads to light striking on full auto. Basically, after a few hours of work, by: ' - Degreasing everything - Chopping the inner barrel down to 16", added an AK47 thread nut - Modifying the trigger box to fit AK47 mags - Modifying the height which the mags engaged to the blowback unit, in order to get better gas route seal - Shimming the outer barrel to barrel trunnion - Chopping the recoil spring - Cutting a deeper engagement area on the hammer for the auto-sear. - Reinforcing the trigger box - Chopping the flute valve spring to release less gas. Now I have an AKM at 460fps with stuff all cooldown. More pictures to follow. Now, since it uses standard AEG style receiver cuts, has anyone considered using a WELL to converted a JG/CYMA RPK to a GBB?
  20. It's just a bit strange that no one in the English speaking world has done a review on the "new wave" MP7. I hear a lot of raves on the VFC MP7, which while I am sure is 1:1 and kicks like a mule, it is also significantly lighter. After witnessing the video review by nugentgl and seeing the complexity of the VFC, not to mention the 2 piece (plastic?) inner frame and barrel, I decided that the "new wave" MP7 was a much better engineered beast which deserves a little more exposure. I have owned many^2 airsoft guns in my time, so I will draw upon the experience from the other guns that I have had as well. I am not the person to make pretty pictures or write fluffy sales pitches, so this is a no BS, first impression + technical and performance review. ......................... I saw this thing at the local airsoft store the other day, and I wasn't really gonna get it. Having owned a KSC MP7, KWC Mini UZI, and still own a KSC MP9 and a VFC MP5, I didn't see a point in another SMG/PDW. But the sales guy knows I am curious and tempts me with this relatively internet-obscure gun, took it out of the gun cabinet and let me fire this. One full auto dump at 15*C and I was hooked. It was loud, my ears rang. It had kick, was enough to offset my aim on single hand semi and on auto. It had ROF. It had no drop in ROF. I chronoed this at the store, and it was around 360fps on 0.2gs, for a relatively cold day it wasn't bad at all. After some um and ahhring I parted with my cash. My wife is gonna kill me. Here is the box it comes it. It comes with the sights, rails unmounted. It also comes with a disassembly allen key, a thread adaptor for a 14-ve silencer and a spare stock stopper (not steel). Here is the comparison between the 4 different platforms: KSC MP9 is at 1.8kgs, 5" barrel, 1:1 WE MP7 is at 2.1kgs, 7" barrel, 1:1 VFC MP5 is at 2.5kgs, 8" barrel. 1:1 DE UMP is at 2kgs, 8" barrel Here is front side, its pretty typical plastic from WE, similar to their G36/G39 plastic, with a finer texture. Everything that needs to be metal is metal. Flash hider/barrel/gas block etc. But its typical WE metal; i.e. mixture of zamak and aluminium, with a touch of steel/hardened stuff at most of the high stress places (which I will get to later). Here is the 4 position stock, which is a blessing as the half setting is just right length for CQB but no good with a mask. Here is the mag, rather uninteresting, it is double stacked with an exposed front, similar design to a Marui, but bigger. Here is the front, with the flash hider removed, that notch above the barrel is where we can adjust the hop up. Here is the sights, again, just an MP7 sights but ok in quality and looks the part. Its just not steel. So far, its just a fairly standard MP7, abeit 1:1 in scale, and weight. Now lets take it apart. Pop the take down pins and remove the stock here is the bolt group Its partially hollow on the top, but has all the right bits in the right places. Now to remove the mech, what we need is that allen key and remove the selector and bolt catch: Ok here is the surprise: Casted and milled aluminium mech. No wonder why it is so weighty. Not a 2 piece plastic jobbie like the VFC, and not a million springs fly out (just 3). Its even easier than the KSC/KWA or the Marui MP7 to take apart. Here is the barrel and gas block assembly, note the anti bounce buffer on the gas block. Barrel is rock solid with no wobble or alignment issues: Its aluminum. Secured via two screws at the bottom of the mech, and this disassembles the hop unit also. Now looking at the mechbox here is what interesting, chrome/steel hammers and seers. Its not chrome plated pot metal (more to that later). ................. Function: Now this is where it gets a little interesting - The trigger release on the New Wave MP7 is not the best. Like others in the SMG 8 review have found that its mushy on semi-auto. In fact, I have to pull it all the way back before it will release on semi. Certainty very unsatisfactory and does not bode well with a CQB platform where quick trigger response is required. But with a dremel or a good needle file this can all be fixed. Looking from the right side of the hammer this is what needs to be done to the right side sear contact point (not the left side one as that is for the auto sear/bolt trip). I would dremel that part half way and then slowly file down gradually, testing the trigger release. The optimum result is: On semi, trigger releases @ half pull. On Safe, trigger does not release. On full trigger releases @ 1/4 pull. If you over file: on safe, the gun will fire, and that would really suck, so file gradually after half way. So now, its ready for a proper test. At 8m on .25g its giving a 3cm group, which is fairly decent given its a short barrel rifle, but could be a lot better. But here is what happens at 50m, It shoots straight...straight but high...straight but low...hook left, hook left, hook right.....straight...straight high... What is happening is a classic example of a shoddy designed hop rubber. So I took the barrel assembly apart, unfortunately no pictures... 1) The inner barrel moves ever so slightly around the outer barrel. 2) The hop adjuster is a 2 prong design, has no nub and is hard plastic 3) The hop rubber is the Marui type BUT the alignment tab is at the front rather than at the breech end. If you need to change hop rubber you will need to cut off the tab. 4) The hop rubber has the same issue as the KSC hop rubber, which has a constrictor ring cast'ed inside. BB doesn't drop through the rubber it gets stuck inside the hop rubber. Here is the fix, same as the KSC/KWA NS2 hop mod: 5) The hop adjuster doesn't push down on the hop rubber as it actually hits the barrel instead . Here is the issue, and the fix : I also teflon taped the hop rubber and the barrel, added a sliver of aluminium superglued into the outer barrel as a bushing to prevent the inner barrel movement. I am getting consistent hop trajectory at 50m with .25g, at 340fps on 0.25gs @ 15*C, 1cm grouping at 8m on the stock 7" barrel. Compared with SMG/PDW at a similar class. VFC MP5 with Marui Hop rubber mod, 8" barrel, 340fps on 0.25gs @ 15*C. Kick is there but but not as strong as the MP7. KSC MP9 with Modded KSC hop rubber mod, 5" Barrel, 340 on 0.25gs @ 15*C. Kick is the weakest out of all 3, but ROF is the fastest. Since all 3 have had mods to the hop, the Mp5 is the most accurate at both long and short ranges, but the MP9 is pretty much the same as the MP7, MP7 has an extra 10m more of range than the MP9 but that could be how the hop is currently set. Conclusion:

    "New Wave" Small Rice 7 (MP7) Review

    Old WE GBBRs such as the MP5/MP7 had overly strong rocket valve springs and recoil springs. Rocket valve springs can be chopped by 1.5 rungs while recoil springs can be chopped between 30-40%. That will increase the efficiency. And no its not the #049 that eats away at the bolt, it is the hammer.

    "New Wave" Small Rice 7 (MP7) Review

    Since I went to a steel hammer/trigger sear set there has been no wear. http://shop.kic.tw/portal_c1_cnt_page.php?owner_num=c1_33589&button_num=c1&folder_id=7632&cnt_id=88590&search_field=all_field&search_word=smg8&search_field2=&search_word2=&search_field3=&search_word3=&bool1=&bool2=&search_type=1&up_page=1 But the hammer, will then wear out the bolt carrier due to a few design issues. Long story short, WE's hammer design, when replicated with steel, will wear the valve release areas on the bolt carrier. The biggest issue isn't that. It is over time, the pin that holds the striker in place will bend from impact, leading to a decrease in FPS and irratic full auto. To solve this you need to temper the pin, and then modify the mechbox so that striker assembly stops not by where the pins stop, but at the front of the striker area. So far, no other issues have popped up.
