Use on a 300 ultima patrol - Strike Industries Beretta 1301 TAC / A300 Ultima Patrol Red Dot Sight Mount

Just installed it in the A 300 Ultima Patrol and it looks great. I’m using a Vortex Defender XL and it is more like a lower 1/5 co witness. Just be aware that even though it says that it works with the DPP foot print I’m not sure it’s truthful. I am able to mount the defender xl but only using the 2 front recoil lugs and rear mounting screws instead of all 4 recoil lugs (front and rear) and the screws.
