I have put a stud in the front bolt location , for bi-pod use only .

I bought a UTG Bugbuster scope, which comes with QD Mounts , and bought some QD mounts for the Photon XT
so now i can change from day scope to night scope in seconds , with very little or no change in zero, once initially
set up. The picattiny rail , is extremely handy.

I have a BSA r10 SE .22 FAC locked up in the gun cabinet almost redundant!
