I know the 300BLK is built to fit AR 5.56 mags, and BCGs. Are lowers labeled 5.56 able to handle the round too? Anderson has a lower I like, but it is only listed as 5.56 while they're selling a 300BLK also but doesn't have what I want.
So I'm looking to have an extra BCG for my 5.45. My question is whether the carrier is the same for all calibers? 7.62,5.45 and 5.56? I have a bunch of 5.56 bolts and carriers and might just pick up an extra 5.45 bolt.
Does anyone know if a stock or forearm from a benelli M1 super 90 semi auto fit and work on a supernova?
Looking into using an old surefire forearm from M1 S90 on a supernova since surefire doesn't make one supernova specific
Same goes for the stocks.
