I was having cycling issues with a recent build. I was using a BCG from another company. I sent the BCG back for that company to repair or replace. Aero Precision pops up on my email with the NiB BCG on sale. 15 % off, not a bad price. So I decided to try the NiB in my problematic build. WOW, my gun runs great. The BCG looks and functions great. The other BCG will go in my spare parts bin when it comes back. Thanks Aero Precision. (Posted on 7/26/2017)

Bought one of these BCG's a couple years ago for a build. Had heard good things but wasn't expecting to be impressed as much as I have been. Two years later, after thousands of rounds, this NiB BCG looks amazing (some discoloration from carbon but has zero effect on function) and shows almost no wear. Highly recommend this part.

1st A.P. purchase...finish is good, but not perfect. Review by Phil

I ordered this BCG along with a complete m4e1 upper and lowers (upper just arrived today and I am BEYOND impressed!). The BCG is definitely slick, well constructed, etc.. I was a bit underwhelmed by the polishing The finish is not mirror as depicted in some marketing photos, nor completely consistent in its polish over the entire surface. I also was a little let down that there was no "A" on the side as in some of the photos online. (Posted on 2/24/2017)

Recently bought this BCG and finally had a chance to put some rounds down range. I must say I've seen a few other brands of NIB BCG's and they were nice at first but turned to a nasty tarnished color quickly and a few chipped were the hammer strikes. The Aero BCG after 1k rounds of 5.56 hasn't even looked like I used it yet. Quick wipe down and literally little to zero scrubbing and its clean and still feels oiled its so slick. My AR runs smoother and the action is a little quieter when cycling the bolt. Don't hesitate to buy one for your rifle, Aero quality here is top notch!!! (Posted on 9/13/2016)
Smooth fire and easy peesy clean Review by MasterORTech

Replaced the standard BCG in my Del-Ton AR. I had around 700 to 900 rounds with that. It cycled fine but took me way too much time and effort to get it clean. This BCG cycles so smooth it's actually up'd both my shot rate and accuracy, not to mention after 400 rounds it was strip, wipe, lightly oil and boom done. Will get another for my 300 blackout build. Got it on special for a good price too. (Posted on 7/11/2016)
