I have bought several of these and all came in perfect condition. Good product for the money and the manufacturer is legit. The nitride coating makes for a nice look and the beveled edges make it fit and function well. Throw i on a little TW-25 and you are set.

It may not be one of the big names in AR gear but it does the job and saves money. I matched to an Andro Corp barrel and had no problems.

So this BCG is actually discontinued by ACI. I found this out when the BCG would not fit nicely into the upper receiver. It was really tight and scraped the insides. So I contacted ACI via their website email and they got back to me really fast and told me they could replace the BCG with any one of their new models which was awesome. Amazing support from ACI. I received the new ACI BCG in Chrome finish and this thing is a beaut! I’ve put about 200 rounds through it so far with no malfunctions. Highly recommend the company.
