The lower rear section of the bolt carrier must measure 2.20"+- in order for the Safety to work correctly. Using a 2.40"+- BCG can damage or break the lever. The upper receiver must be trimmed flush with the rear take down lug to give the lever the proper clearance. This is not a "drop in" part. We do not accept returns for modified parts.

Arrived as advertised and appears to be a quality product. I have not installed yet so not sure on function.

I got this for my AR-308, and while I haven’t been able to fire it yet, it’s functioning properly during function tests. It went right in, without any modification needed.
