quick change roll pin?
quick change roll pin?
good idea, i guess. just not to sure why i would need to change a barrel on it that fast
Its more for the original design concept of the UMP, where you can change the bolt and barrel, and swap calibers real quick.
With the USC, and our ranges, it could always be good to swap between the UMP barrel for short range stuff, or put the USC 16" barrel in if you want to do some more precision shooting, or longer range shooting (say 100, 150 yards).
The USC barrel is a target barrel after all![]()
Can I bring it to the range then swap to a shorter barrel (making it restricted) shoot it, then switch back to the longer barrel to keep it non-res...?
Extra evil points if you have a flash-hider and a folding-stock & pistol-grip and it's black in colour.
Where did you get the short barrel?
