My 450 BM is the factory 16 inch version.
Thanks! Any insight is appreciated!
I bought this handguard for my last AR build. It was a 5.56 mm, but there was no problem matching the barrel nut to the upper. I did have to buy a low profile gas block. This is a slim line handguard, so the gas block on the stock 450 BM may be too tall to fit under the handguard.
