Hey y'all. I want to take my browning bps10 and mount it under a ar15. With a 19" barrel to the back of the action its 28" . A 3" 12 ga with 19" is 26.5" overall to the action. I see that usually a m203 mount is used. How does that part mount to a shotgun? Drilled & tapped? . Probably mount it on a rifle not carbine sinse it would be kinda long. Oh yeah the bps 10 ga is a 4+1 capacity don't know what they usually use for 12 ga masterkey
 
Re: want to masterkey my shotgun

The Master key is a weapon that existed wayyyy before sons of guns.

Knights armament

The mount is diffenernt than a M203.

They did have a place, at one time but CQB tecniquies have changed.

They are a PIA to hump, very front heavy.

Yea, I agree, they existed way before "son"s of guns." Seen alot of operators try try to make then work. In my opinion, much more efficient and safe letting the TL, ATL, ot dedicated breacher employ a secondary short barreled shotgun in the breaching sequence.

Naw I think the underbarrel chainsaw is more over the top. Also I you could mount a scope to the ar then piggyback a fastfure to it and set the shotgun to aim with the fast fire. Also I see they make a standalone stock for the mount I wonder us I could just use the mount and the standalone stock on the shotgun so I can have a detached grip. They don't make a ar15 stock adapter fir it.
