Update to previous review.... Review by PHIL

FINALLY, as summer's winding down and time has freed up, I was excited to get out and put the first rounds downrange w/ my m4e1. Discovered that the weapon system is deadlined due to improper short side head spacing (marring up casings and even complete separation of bullet from case when ejecting cartridge). Sub'd help desk ticket...very slow responses. I am a local customer and am still forced to deal with waiting on pre-paid shipping etc as they won't let me drop it off in person. To top it off, my teammate from Iraq will be in town tomorrow visiting and thus our plans to go shooting are ruined. I trust that eventually AP will resolve the issue and will update review at that time appropriately. Wishing now that I had made a different decision w/ regard to sourcing given the great local manufacturers in WA state. (Posted on 8/31/2017)
Expect a small break in period Review by Nicholas

I ordered this to toss on a lower I had. Went down to the range to kill some paper and had nothing but problems at the start. First off, do not use an H2 buffer or the Super 42 setup. It's too strong. After that debackle of failure to feed and failure to lock to the rear...... I put in just a standard carbine spring and buffer. Should have worked right? Well sorta. Now I was just down to failure to lock to the rear.... hmmm. I take it apart and inspect, can;t find anything. Put it back together and just start running through rounds, after about the 100 round mark it started to run perfect. Continued to run another 400 rounds through it without any failures. So yea, love it now. (Posted on 3/27/2017)

I bought one of these uppers for carbine build and it functions flawlessly. The fit and finish is excellent and it works just fine for me with a non-AP bolt. Rifle is fairly accurate as well. Very easy to keep it within 2.5 MOA with cheap ammo and a red-dot. (Posted on 3/3/2017)

I just received the upper (along with a NiB BCG and waiting on a complete lower to finish the build) and I couldn't be more impressed. Finish is AMAZING! Feels like exactly what you want in your hand. This is the way reputations are earned! Great Job to the A.P. team! (Posted on 2/24/2017)

Glad I was lucky enough to find this company online, this upper is nice and good quality, I like the design much more than the competitors, simply because its not rounded. Its sleek and good looking. Fires like a champ. Great customer service as well. (Posted on 8/2/2016)
