Airsoft Masterpiece Hop-up Base Plate

"Pros:

Strong
Soild

Cons:

It was temperamental inside my stock tm 5.1 hop up wheel, like the other reviewer said last year, the end nub that fits the wheel is little thicker. It binds in my wheel, works when it wanted too. All in all nice arm, ill save it for when I upgrade to AM hop and wheel. For now back to stock, shimmed with diy I key.

"Worse then the stock arm on my Secutor Arms XI 1911 but thats not their fault. Probably works great with the Airsoft Masterpiece hop up. Just not mine. The two protruding nubs that press onto the bucking aren't the same size. The one closest to the hop wheel is larger then the furthest which in my opinion should be the opposite considering most hop up arms like these almost always pull toward the wheel side than the other. Maybe one day we'll get some sort of rotary style hop up for GBB pistols! Wouldnt that be kool lol
