Exactly as advertised by water, April 2, 2020
I was looking for a inexpensive way to finish off my pistol build and this worked great. I don't know how long until I add a brace, but until then this will work. Resting the brace against the cheek to fire isn't nearly as cumbersome as I thought i...

Tube is too short by GirlDadOf3, Verified Owner, July 13, 2021
