Product Description

Adams Arms 16″ Carbine 5.56- Piston Upper w/ Magpul MOE guard black

In our opinion, Adams Arms makes one of the finest AR-15 uppers on the market today. Their piston system increases reliability, reduces maintenance, and decreases felt recoil. Their system is simple and intuitive, making it easy to clean and take care of. The melonite coating on their barrels is a significant upgrade from the chrome lining used on most barrels, offering both improved performance and increased barrel life. Fit these uppers to any quality AR-15 lower and experience a new level of AR-15 performance. These uppers come with the complete bolt carrier group These uppers come with a standard AR-15 charging handle The gas block is pinned The muzzle device is a standard A2 and it is not pinned Adams offers a lifetime warranty and we have had great warranty support from them We recommend the Magpul MOE M-LOK Handguard, the Yankee Hill 2-Piece Piston Quad Rail, and the Daniel Defense Omega Rail for these uppers. There are other compatible options.       https://youtu.be/l_ZYfBHbc5s

    Bought this upper last year for my AR15 project. At first I was hesitant due to the lack of field experience on gas piston, but my doubt was overturn by the excellent performance and ease of operation of the Adam Arms Gas Piston system. I am in the process of building another AR15 and Adam Arms Gas Piston is my preferred upper. Also, justin hooked me up with upgrades on my upper. Excellent CS. Shall await my discount promo.

    I finally got around to completing my AR rifle and taking it to a range. This is an extremely smooth shooter. The piston action is different in feel than a regular upper. No mis feeds or failure to fire. Shipping was quick. I would by another and I am recommending this upper to friends.

    Great upper for the money. I have only run about 200 rounds through so far but it ate everything without a hiccup. Used 62g M855, 62g Silver Bear, and 55g ball of various makes. All POI’s were within 1 MOA of each other.
    This upper runs clean! After spending most of my military career scrubbing filth out of a BCG, this was a major plus. It fit flawlessly on an Anderson Mfg lower, with zero play. The gas piston is very easy to remove and clean.
    Loved it so much, I bought a second one for the wife.
    Western Sport has thus far been great to deal with… accurate orders, fast shipping and great prices. Will be back.

    So glad I ordered the Adams Arms piston upper from Western Sport. The Shipping was very fast. I mounted this upper to a Spikes Tactical Lower, only negative thing I can say about it is that the pivot pin and take down pin where very tight fitting. I had to use a rubber mallet to get the pins all the way in. I messaged Adams Arms about this and they were very helpful and said that using the mallet would be fine and that it should loosen up after a while. The front pivot pin has loosen up enough now that I can take it out by hand. The rear take down pin is still tight and I have to use a punch and mallet it to get it out but I can put it in by hand, so it’s loosing up some. Its not a bad thing for it being tight. I would rather have it tight and the upper not flop around. As for the performance of the upper, it’s excellent and I would highly recommend getting it if you’re looking for a good quality piston upper.

    I like my Adams so much, I built one for every member in the family. They are so easy to keep clean compared to DI systems, I run all different types of ammo threw them and I didn’t have any issues. Customer service has always been very good I recommend this site to all my friends.

    These upper receivers are great. Adams Arms piston systems are a very great value! Western Sport was also able to provide exceptional customer service with a problem. Thank you!

    0 complaints besides the basic charging handle, but that’s to be expected. Works great and I’ve had no issues. Hopefully one day I’ll have an appropriate suppressor to put on it to see how the gas is, but I suspect it will be tolerable. Just wish it was $400 when I bought back on Black Friday during the gun scare ($500 back then was a decent deal). Almost tempting to buy another for no good reason besides the price…

    I have two of these, and they run fantastic. I brought one and a direct impingement AR to the range. The difference in soot and crap on and around the bolt carrier was astonishing. These just run so clean that it makes post-range cleaning a snap. If your building a 300yard+ AR-15 then go with DI. If your going for medium to short range then this is the upper to buy. The melonite treatment on literally every critical part on the gun, makes this a long lasting and durable upper. My 1st Adams Arms upper STILL has little to zero wear marks due to the melonite treatment. Yes I do use gun oil, but that’s just proper. If I could give it 6 stars I would. No failures of any kind, 100% reliable and would use it to protect myself any day.
