Like the BCG

Posted by Anonymous on Nov 20th 2024

Purchased this 308 BCG for my very first build. Putting it in a Stag 10 upper. I like the way it looks and can't wait to finish the build. Was the best price I found for the nickel boron. Shipping was fast and easy. Would do business with this company

was concerned about the price, but this turned out to be a great investment, runs great, easy to clean, not one single problem turned up, so i purchased another one. i think i may get one for my 5.56 rifle also, we will see after i run these hard for a while

Bolt carrier was replacement for one was having some issues, ran really well in my recent build while I was tuning the gas system and buffer weights (another issue), after testing cleaned up very well with light cloth and mild solvent and CLP, overall very happy. Will need to put more than 20 rounds through it later. Bought another one for a different rifle and hope it works just as well as this one

The product is very good, as usual. I've never had a problem with Acme products or service, after 3-4 years of buying from them.

This is a great piece! Attention to detail is well appreciated. Operates flawlessly in my Springfield Saint and Sig 716i TREAD. Would highly recommend.

just did the final adjustments and build of the big bore,have not cycled any rounds through the gun yet but the bolt and carrier look to be of excellent quality and a little more than full mass so I am pretty sure that as long as I adjusted my headspace to spec I won't have any problems.
