Roecar Posted June 14, 2009 Report Share Posted June 14, 2009 how do i get the locking bolt catch to work? Â I second that, there was a video review of an AGM on youtube and they said they'd post another how to fix it but I have yet to see it. From the looks of it it appears that the bolt catch is a bit to "tight" for the mag lever to activate it. Anyone figure how to fix or mod this yet? Quote Link to post Share on other sites
sin415 Posted June 14, 2009 Report Share Posted June 14, 2009 from what ive read on ASR is to clip a few coils from the bolt catch spring to engage properly but i myself have not tried this sounds like a good idea thought , just my 2 cents Quote Link to post Share on other sites
snorkelman Posted June 14, 2009 Report Share Posted June 14, 2009 right just about to pull the trigger on these parts from RA-Tech  background to intended rifle - I'm not too fussed about ROF, aiming for around 300 to 330 FPS with a fair amount of recoil.   RAG-WA-bolt-015 NPAS complete bolt dimgray $260 RAG-WA-bolt-016 red Oring $2 RAG-WA-triggerset-005 bolt stop $15 RAG-WA-triggerset-004 Steel hammer $70 RAG-Wa-trigger set 003 Steel sear $10 RAG-Wa-front sight-001 WA M4 CQB Hop up chamber $55 RAG-Wa-front sight-004 WA Hop rubber $7 RAG-WA-stock-001 recoil spring winter type $10 RAG-WA-stock-002 recoil spring summer type $10 RA-A-G-GHK007 GHK M4 GBB Mag $50  hop rubbers and orings I figure a couple of each as spares the GHK mag I might as well try one (as total orders big enough for free post on it anyways and Id like to copare it with their AK mags)  questions  1 Hop unit - worth going with the RA-tech one I've got pencilled in above (not sure if its even metal) or are there better options in that respect. Not too fussed about ease of adjustment - if I can dial in what I want and it stays there thats fair enough, more concerned about strength of the unit and effectiveness  2 steel trigger, fire selector and mag catch - are the ones from WGC suitable for use along with above? ie any known issues with RA-tech steel hammer and sear?  3 any recommendations for replacement buffer?  4 At some stage I'm likely to ditch the receiver in favour of something CNC'd from billet that I can anodize in a hideous colour am I correct in thinking that if that turns out to be a Prime one, I can keep the guts of the RA-tech steel bolt carrier assembly, and just replace the RA-tech steel WA bolt carrier with their Prime one  ie shove the bolt and npas etc into 'RAG-Prime-001 steel bolt carrier Dimgrey $130' or are there dimensional changes to the setup over and above the carrier itself? RA-Tech are listing complete Prime bolt carrier and NPAS assembly as one item and the Prime bolt carrier on its own, theres no corresponding Prime specific innards listed on their own which makes me think only difference is to the carrier itself Quote Link to post Share on other sites
Roecar Posted June 14, 2009 Report Share Posted June 14, 2009 (edited) from what ive read on ASR is to clip a few coils from the bolt catch spring to engage properly but i myself have not tried this sounds like a good idea thought , just my 2 cents  Well "fixed" mine but I didn't quite do it that way. I saw the little nub thing that holds onto the bolt catch and "shaved it down to the point wear it will still secure itself but the mag will still have enough force to push it up when its empty. If anyone one else wants to try this just use an Xacto Knife and carefully scrape the surface until you can "easily" punch of the bolt catch with a little applied force.  ADDED EDIT** I want to add a CTR stock on my AGM and I want to be sure which type it is. My calipers say the dimension for the tube is around 1.149" and I know the CTR Milspec is about 1.14. Anyone install a CTR on an AGM buffer tube?

3vi1-D4n Posted June 14, 2009 Report Share Posted June 14, 2009 (edited) A shorter inner barrel won't decrease FPS that much. The trick is to push the Negative pressure valve more "forward" by gluing something behind it to push it forward. It limits the gas flow to the breech/barrel. Â I experienced my first gas leak this weekend. I fired off the gas, and I left the mag at very low pressures for a minute, as soon as I went to charge it the propane was going straight through the mag. Â Knowning WA design (The AGM mag is a near copy), I thought it was the gas release "hold open" mechanism on the mag, which keeps the valves open for a certain amount of time, and if the rifle/pistol has discharged its gas while firing, the mechanism will open the valves until disengaged. It wasn't the case. Â The 2 O-rings on the release plunger (one that actually blocks/releases the gas, and a smaller one that seals the release plunger assembly) had been deformed and dried up. I changed the large one out to a tighter neoprene O-ring and repositioned the smaller one and the leaking disappeared. Â I think that we just need to be smart about leaky mags. O-ring stores can get you most of the O-rings for a fraction of the cost of ordering overseas. Also bearing in mind the guns are made from the lowest bidder of parts.

snorkelman Posted June 14, 2009 Report Share Posted June 14, 2009 Ra-tech stuff ordered, still looking for a trigger, selector and mag catch - just standard style ones no ambi selectors/mag catches or funky triggers  any views on LCT versus G&P for those?  Quote Link to post Share on other sites
tinydata Posted June 14, 2009 Report Share Posted June 14, 2009 First after action report written for my local forum:  Well, after a first day's skirmish at TAA, I am absolutely astounded.  First off, everything was chronoed on GB .2g BBs, duster gas, and green gas  Green Gas: 423 fps  Duster: 308 fps  Well within limits for outdoors and CQB play. Perfect...  I used the original mag today. Didn't leak horribly or misfeed at all. One fill of gas was enough for at least 100 rounds. The bolt face and hop-up are still in amazing condition, with no wear at all.  As for the skirmish report, it performed wonderfully. No jams, catastrophic leaks, or problems whatsoever. The accuracy was great. I scored quite a few headshots and was able to place a single BB where I wanted it. Lots and lots of single shot kills. Blowback was crisp and loud enough to give off a nice report. Full auto, though sluggish, worked perfectly. So, would I recommend it? YES! Quote Link to post Share on other sites
3vi1-D4n Posted June 15, 2009 Report Share Posted June 15, 2009 (edited) Good to hear. Mine has had 900 rounds through it now. On the first day I noticed the bolt face was uneven as the extractor flap stuck out a little more forward than the rest of the bolt. So I sanded it down so the pressure was taken away from that area. Hop is fine and is not broken at all.  And yeah one gas charge is enough for 100 rounds if it doesn't leak  I noticed with the hop on optimum its perfect for 0.25gs but no good for anything heavier. Is this the case with the others? Edited June 15, 2009 by 3vi1-D4n Quote Link to post Share on other sites
RUSHER2 Posted June 15, 2009 Report Share Posted June 15, 2009 My rifle has been great so far the only problem is that my hopup broke! so i replaced it with a Pro-Win hopup that i can use aeg berrels so i have a Tightbore in it know and it is on the dot accurate and i get ALOT of range perfectly straight. everything else is going top notch!

RUSHER2 Posted June 15, 2009 Report Share Posted June 15, 2009 Well, Here is a summary of the AGM: Â Neutral: - - Spring Twangs in the stock tube. Â ---------------------------- Â To let you know this is normal very normal. It is like this in a real AR when you fire the rifle the bolt goes into the buffer tube about half way this is why you hear the "clang of the spring when you shoot it.

stickyittoyou Posted June 15, 2009 Report Share Posted June 15, 2009 Just put in my new ratech hop and alum npas bolt set......... Couple of things to note everyone:  1.) There's a reason the BBs roll out the barrel. The O-ring that is supposed to be on the hopup lip isn't there, it looks like they used some crappy waxish paper instead :/ 2.) The Alum npas nozzle doesn't fit very well at all. Its very hard pull the bolt face out and let the spring retract it. 3.) No matter how I adjust the npas it doesn't seem to cycle enough or something to chamber a new BB.   Now with the npas set to full power, its driving .3g bbs almost through sheet rock  EEEEep! Dude have someone stand around the side of your house (covered by the house from you shooting them) and shoot by them. I want to know if they can hear the air being bent around the BB. My friends KJW M700 does that... lol it's scary...  I went onto the RA-tech youtube video of the AGM and asked them that compatibility, apparently everything works. The bolt catch is the only thing that needs a modification. I wonder if they'll show us how.  "Hey there RA-tech I have a question. I want to buy an AGM GBB M4 some day, for upgrades I plan on getting a G&P Metal Hop-up and Barrel Combo, your RA-tech full NPAS Bolt Silver (260USD version), I know I need a few other things. What would you suggest for me to get? without breaking the bank that is."  The guy told me that those few things was all I needed to make the gun better. I of course know that I need to get stronger pins (Hammer pin and such) , and replace whatever else that is plastic to metal.  I'll get a 6.01mm tight bore later on. Right now I just want it to run without killing itself.  For the mags... all I have to get is the G&G seals? I saw the page on the other forum on how to. Quote Link to post Share on other sites
