M4 feed ramps?
Posted: Thu May 14, 2020 8:44 am
New to the forum and building a 450 BM upper. Looking at stripper uppers I was leaning towards the Areo XL as I have several other Aero uppers as well as lowers and appreciate the quality. The spec sheet of the XL upper says it has M4 feed ramps which doesn't make a lot of sense to me for the 450. Will this work without modification? I want to shoot Hornady 250 XTP's and they aren't a pointy bullet.
TIA, Rod.
