I just put this together for a friend Phase 5 lower with Adams Arms P2 adjustable gas piston upper https://i.imgur.com/6LomimC.jpg Nevermind. I called Adams Arms and they told me you have to use a screwdriver to adjust it. |

I wanted to offer a brief testament to their customer service.
I built a 12.5" SBR in .277 Wolverine. Its a wlidcat round (I think they got SAAMI certified now) based on the 5.56/.223 case but with a .270 projectile. It's a badass round, gives you near .270 WIN ballistics in an AR platform. I built it with an Adams Arms upper and piston system and I couldn't get it to function reliable, with or without the suppressor. I happen to live only about 30 minutes away from them. I called Customer Service and they told me to bring the rifle by. I dropped it off with my suppressor in the morning on my way to work. By the time I was leaving work, they had it ready for me. They had slightly trimmed the drive rod. They replaced the drive rod spring. They opened the gas port on the barrel in several stages and tested it each time until they got it reliably functioning suppressed and unsuppressed. They even saved my brass from the ammo I gave them. They handed me the rifle and with no bill. Free of charge for a round they don't officially support. I was blown away. I took the rifle to the woods that fall and was able to take my personal best 10-point buck with it. They are great people and I will not hesitate to do business with them. |

Never had to deal with their customer service, but I retrofitted my AR with their piston and XLP gasblock a few years back and couldn’t be happier.
Never going back to DI, their stuff is well made, and they ship quickly |

I built I want to say 5 rifles with piston units, about ten years ago. Four have Adams arms units, one is a full length rifle the two are mid length and one carbine. Two are 6.5 Grendel two are 5.56, then odd one a 5.56 with an Osprey unit, because I wanted to keep a AR15 close to original looking, same front sight block and hand guard . Honestly none have been shot a lot but there have been absolutely no problems with them. There was something wrong with one of the Adams Arms conversion kits, but it has been so long I cannot remember what, except that they were johnny-on-the-spot in taking care of it.
I have never had or will probably never had a suppressor, unless they make them totally legal with no federal tax requirement, and the cost comes down a lot. I absolutely love those unit in the way they keep the receiver cleaner, no going back to DI for me. |

I just purchased a 14.5 Evo upper from Joeboboutfitters.com and took it out to the range today. I put about 140 rounds through it and it almost never cycled properly. Only about 10% of the rounds worked correctly and most of those were near the end of the 140 shot. About 1/4 of the time it failed to feed by catching the following round at the middle of the casing. The remainder were failure to pick up the next round but it did eject the spent cartridge but I did have a number that were not even ejected. I was actually coming on this forum to see if someone could help with suggestions

Looks nice! I can’t wait to get my micro evo in November. Only thing is I’m gonna have to upgrade to an m-lok rail so that’s $200 extra to start! Plus I’m gonna get the low mass BCG and ambi charging handle and different muzzle break. Then all I have to do is find somewhere to get a cerekote job done to get the color I want and magpul furniture, $800 for rifle and another $600+ right out the gate! But from what I’ve heard I think I’m gonna love it and I can’t wait to throw some lead down range!

I picked up one of their uppers on sale, initially it was not ejecting steel case ammo, but brass was ok. I contacted their support and they had me polish the polish the barrel chamber and it resolved the issue. Took some time to get in touch, but seemed like good people, they said if it was not resolved I could just send it in, so as reported by most, their support seems good.

I can't speak to their CS, because I haven't needed it.
I do own a factory assembled Adams Arms AA-15 Evo Carbine. Its a nice gun, but a little on the nose-heavy side. It appears to be a quality build, but I haven't fired it enough to really know for sure. The most telling part of my post ... the gun is on the exchange for sale or trade. This isn't a knock on AA, but says how I feel about piston ARs. They seem to be a fad that is passing for most (but not all). There are so many good dedicated piston designs available its hard to "love" a piston AR. |

How about a 20" complete rifle or upper in .308? maybe ala carte? the 308 bolt carrier, 308-specific gas block which I assume would be a skosh taller than the AR-15 GB, and then a selection of push rods. But then you still have the problem of how to mate the op rod spring cup, to what? To the non-standardized who-knows-what barrel nut (rail mfr dependent?), or directly to the upper receiver face? I guess I'm seeing the why-not. unfortunately. maybe as a barrel + rail package, or even a DPMS-pattern large-frame AR-308 drop-in upper, Voodoo 308 barrels, but that's no longer a conversion kit.

I have a 14.5" Faxon mid-length 7.62x39 barrel with Adams Arms piston conversion, pic rail gas block. My mistake, 14.5" mid-length gas doesn't allow a lot of dwell time, and the low gas-port pressure, shooting 100% Wolf steel-case ammo (I'm cheap), compounded with the piston conversion, took a lot of trial & error effort to get it just right. gas port in the barrel is drilled to 0.1520" (#24 drill). the vertical gas port channel in the AA pic rail GB is already 0.157" (#22 drill), and I also had to drill the gas plug out to 9/64" (.1406"). it uses a standard M4 carbine spring with a Spikes T1 3oz buffer. If i switch to a T2 4.2oz buffer, I don't get last round bolt hold open. If i put the standard AA 1/8" gas plug in with the T1 buffer, also no LRBHO. It shoots nicely, though.
Consequently, my next 14.5" 7.62x39 AA piston gun was a carbine gas length.

I couldn't recommend them. I bought a small frame 308 and found out that the "rifle may not function with the current parts" They were correct. 4 weeks later I received replacement parts. The rifle still failed to function several rounds per magazine with way more recoil and pressure signs on the brass. Now its sitting in my basement while I decide what to do with it. Waste more time shipping a rifle I have no desire to own back to the factory or offload it at a big loss with full disclosure. (Even if it was repaired to function I have no desire to represent a company that has duds on the market)
Granted this is a sample of one and I wouldn't burn a company, with real people working for it, to the ground because of a few lemons. Just not something I will own. Glass half-full I love the Armalite I bought as a replacement! |

Quote HistoryQuoted: With 7.62x39 on a midlength, it can be extremely hard for it to run reliably, you have seemed to work out some of the kinks. My concern that I would like to address is that with the gas port that large, you will most likely start to scrape copper or other jacket material off the side of the projectile as it passes by the gas port. This will more than likely cause the piston system to lock up with flakes of material in the drive rod cup. When a customer states that they wish to run 7.62x39, I try to make sure they have a pistol length gas system, at the very least carbine. You will also need to run our low mass carrier, some gas port "tuning" may be required but it doesn't exceed .125". When you start the carbine build, please shoot me a message so I can verify your set-up, for best results. [email protected]. -Phil- thanks! |
