Recommended Posts

Beside that "S.L.A.S.H." (I still prefer the std RIS)..

does someone knows more or even tried this CNC HUC from Ace 1 Arms:

Just got mine in! as well an apple airsoft nozzle and wii tech ball bearing spring guide. Will let everyone know how it works on the field. (from what I gather, the system is pretty much a standard v2 hopup style)

 

hmm anyone have problems with loose triggers on full auto? if i pull it all the way down, it seems the contacts will get loose and stop firing. If i pull it gently, I can fire full auto with no issues.

Yours definitely had wobble. And it has since been fixed. Who else's has been confirmed to have wobble? Because out of the 3000 units sold so far, yours is the only one that I'm aware of that has been

I like how me pointing out the obvious in my last post has garnered a negative rep. LOL. Haters gonna hate.

I Lol'd at all the fanboys who had to have this must have aeg. To be honest it seems as if youy have all been taken for a ride. My A&K Masada with systema gearbox *suitcases* all over this ares ab

I had a problem with my trigger locking up. Turned out the two switch blocks were not properly seated into the gearbox shell and were sometimes moving very slightly. Solved it with a dab of superglue on the nubs that locate the switch blocks.

Something else you may want to consider is in  this incredibly helpful post on http://www.tkoverkill.com/showthread.php?tid=1307 so thanks to Ycare:

 

 

The selector on the ACR is made of two external knobs, which are screwed to respectively one dented wheel on the each side. The knobs also have a kind of "clicking" position to help choosing between safe, semi, and auto. This is independent of the actual gearbox inside.

The way the selectors on each side "connect" to the selection mechanism in the gearbox, is only through those dented wheels. When you take the gearbox out, there is no way to really know what position is safe, semi, and auto, besides having experience with V2 gearboxes. Thus, sometimes, the gearbox internal selector mechanism, will be slightly misaligned, or "not on the right position", when inserted in the lower receiver, and the results will be non, or bad, functioning selector switches.

Look on the diagram provided with the AEG, you will see which dented wheels I'm talking about.

Basically, to try fixing it, you need to have only the lower receiver, and the gearbox still inside the receiver, but with the attachments removed (bottom grip and 2 small hex screws in the magazine receiver removed). Once this is done, slide slightly the gearbox out (make sure the selectors are in semi, else you might have difficulties, or maybe it's another one, not sure, just try). Once you can see that you have no problem sliding the gearbox out, just try moving the dented wheel on the left side of the gearbox (left side if you were holding it to shoot) a little bit in one direction (or the other), then push the gearbox back into the receiver, connecting back to the dented wheels of the selectors on each side. Connect a battery, and try switching between safe, semi and auto. You'll see that if you turn too much the wheel, or in the wrong direction, safe might become auto, and vice versa. It's no problem, just trial and error and you should be able to find the "sweet spot" where semi will work flawlessly without needing to switch back and forth.

Make sure you have a spring inside the gearbox when you try all this, else the semi might lock up more often than usual.

BTW, finally got my very own Masada :-)

 

S/N MPTS89154

ProLine CQB, black

 

Obviously one of the latest units, as mine seem to have the reinforced GB shell

as well as a red (?) aluminum nozzle..pics maybe later.

Hey guys, finally got my own DMR parts in. Started working on the internals now and would like some advice. 

I know right off the bat that the Wii tech hopup and adjustment nob is a must. And I'm planning on getting someone professional to install a rhop with M nub and swap out the bucking for a lonex 90' one.

 

If building it to be a single shot shooter would I have much to worry about if I was running something along the lines of a M130 with a bore up cylinder set and higher torque motor (maybe SHS?)? 

I'm not looking for a crazy high FPS (since I'd like to be able to tone it down more easily if I ever chose to run it again for a field rifle or cqb role. 

 

Also have you guys that built these found that you needed to actually swap out the inner? When buying the new 18' I learned that these come stock with 6.03s. Do you actually see a huge improvement transitioning it over to a 6.01 or is the benefit marginal and will be more of a headache for cleaning and maintenance.

Make sure to use a Sorbopad and to round the corners of the gearbox shell. The earlier version of the gearbox shell lacks sufficient reinforcement, thus it can easily break on stronger setups.

A 6.01 barrel will not improve accuracy, but it will lead to slightly higher FPS due to the smaller diameter.

Ok, that's what I was looking to learn. Wasn't sure if it was required for something like a M130. Pretty sure it is the earlier version since the grip doesn't have the texture of the miniature magpul logo's and only has it at the base.

I got one of these when it first came out years ago. I noted that the pistol grip on it has the miniature magpul logo all over the grip. I dont think the g&p versions had that texturing. Cant say anything about the sv line.

Has anyone ever tried Frankensteining an A&K Masada's collapsible stock onto a Magpul PTS ACR? :D

A quick forums search turned up no results.

 

I own the PTS ACR and am soon coming into possession of the A&K Masada, and was just wondering if I could save a few $$$ by not having to buy the PTS folding stock.

 

Is the size/scale difference really to the point where the two stocks are not interchangeable?

Made by two entirely different design teams, one of which only had photos to go off.

 

R.e. the last line, short answer:  Yep

 

Haha, after I got the A&K Masada I put it besides my Magpul PTS ACR to compare and nearly fell out of my chair laughing.

 

It really is so much smaller! 

 

Strangely, the A&K feels much heavier than the PTS version. I'm guessing that is because of the lower quality/heavier polymers and perhaps heavier internals.

Post picture. I fear that I can never look at my A&K masada the same way after this.

 

I'm surprised I couldn't find any comparison pics online, but basically looking at them side by side:

 

 

-The A&K's hand-guard is about an inch shorter in length

 

-With both in carbine configuration, the A&K's barrel is actually almost an inch longer (or at least it looks that way since the handguard is shorter)

 

-The A&K's externals are also noticeably of lower quality, especially when looking at the finish on the barrel. The PTS looks realistically metallic, the A&K is just flat black.

 

-The A&K is around half an inch shorter in height than the PTS

 

-You need to extend the A&K's extendable stock nearly all the way, or at least 3 "clicks" to make it match in length compared to the PTS with its fixed stock.

 

 

In all, every piece is scaled down by a tiny bit, which adds up to a much smaller gun in total. The A&K is much heavier for some reason, but it really kind of looks like a toy when I place the two side by side.

I finally got myself a WE MSK modular handguard

and I can tell you, it wasn't easy nor fast to get hold of that part

without buying a complete MSK.

 

However, it does look really sweet

and I thought I should share some pics with you :-)

Installation was rather easy, as I only had to lathe two small adaptor/spacer pieces

to fit it (pics/specs on request), so now the handguard fits very tight.
