Ooohh I like that rail ! My self and a mate both ran G36 support guns for a good while years ago , couple of snail drums , bipod , go prone and bang ! Sorted . His was basically the same as yours and mine was a shorter para version with an Elcan scope on it and a desert’ish camo job like one id seen in Afghn.?
run all my guns on 9.9v LiFe’s now , bar the kitty cannon that eats 11.1v , well she does like to shoot her load as fast as possible! ?
