Burris FastFire 4

Burris FastFire 4 low profile, co-witness mount for Beretta 1301 Tactical. For all the losers who watched too much TFB TV. I printed in 3D Fuel Pro PLA plus @ 215, with a raft.
Mounting holes for the red dot aren't threaded, but they are tight. So the mounting screws have enough to bite into. This will also work with other optics that use the Docter footprint, such as the FF3 and the Vortex Venom.
2nd file has slightly oversized mounting holes for the red dot, because I used heat set inserts.
I used M3x3 inserts, and M3x8 screws
