I definitely like the quality of this BCG. The gas key staking is done right. The functionality and material is awesome as expected to be. Very easy to clean. I will definitely consider this product for my next build.

Like the title says, it has performed flawlessly so far with over 1200 rounds and no jams in my AR15 PSA 10.5 Upper along with an Enhanced PsA Nickel Boron Trigger. The color has lost some of its shine, but the material hasn't rubbed off, flaked etc. Still looks good and most importantly functions well. The staking on my BCG couldn't be better.

I got the cool looking black one.. Looks very nice on her surface packaged well exterior coating looks very nice.. it wasn’t until I started looking more closely that I found things that I’d say I wouldn’t expect. Staking is there but it almost looks like the material pushed toward the bolt is bound to break off as it is separated on one side of the staking from the original material being pushed see. Also closer look of the firing pins shows some unusual markings I assume tooling. I can’t post pictures I have plenty pictures speak a thousand words. Hopefully she runs well I haven’t been able to get out and fire this thing yet but first impressions no so impressed. 3 stars for now we will see after I shoot it if she keeps all three.

Got two of them and they run fine, no problems so far. Clean up easy as well.
