We sent a couple of our in house AimSurplus branded bolt carrier groups over to our friends at 704 Tactical. They were kind enough to put together this video review of them. Go ahead and click the link and watch their review! If you wanna subscribe to them and stay up to date with their videos they are commonly testing AIM parts.
Let them know you made your way to their video from over here and show them some support. Its always nice to support those that support you in the industry and very few places give good honest reviews. Let us know what you think about their video and your experience with our BCGS!
