I did not purchase these buckings here, but i am just warning you, DONT GET THEM they are bad!
-They have an innovative design that supposedly improves stability
-H-Nubs are good
-They are too thick to fit in nearly any hopup unit.
I tried these buckings in the following hopup units: G&P AUG, KWA G36, Lonex G36, KWA m4 TM p90, CA p90 and they were too thick for all of them!
-Too long, required cutting to get it to fit.
-Performance wasnt anything too great. wasnt a large improvement over my KWA stock bucking
-Caused horrible feeding issues.
