"Cheap, lightweight (compared to Madbull DD 10.3), fits Echo1 Platinum VFC receiver perfectly, barrel wobble can be fixed by tightening the Allen screw.
by Sam B. on 07/10/2019
"Fit tight in an APS receiver (which is normal because APS doesn't like anything that isn't APS) but still a good barrel.
by Bradley H. on 02/25/2017
"Very good rail, high quality metal. It works with a G&P.
