This G&P metal hop up is designed for those who have upgraded their Tokyo Marui plastic bodies to metal bodies. Most plastic body M4/M16 have two piece hop up units, when upgrading to a metal body you also need to upgrade to a metal hop up unit. This is the perfect metal hop up to get because it will seal against the gearbox, flawlessly feed BBs, and it is fully adjustable to put the right amount of backspin on each BB.
Package Includes: Hop unit and adjustment wheels
I bought this simply as a replacement for my old hop up, which broke from when I dropped my old gun. I never was anticipating that this would help make my gun much more accurate. Glad to have bought this hop up. Included bucking is a plus, and itís a great buy overall.
None that I can think of. Works great!

For: G&P M4/M16 Metal Hop Up Unit
This Hop up is made with decent quality metal and serves it's purpose as a hop up. Gears are firm, but not as good as other's I've had. Spend the extra money and get the M4 Madbul Ultimate Hop Up. True story by the way: A Crosman Bucking and Nub are better quality than the one they give you. If that tells you anything about the product. Upon installation, originally, the nub sucked badly, and caused jams in my rifle. It provided NO hop up, instead it drastically slowed my shots, or made them spin off in my barrel oddly, then they'd impact on my flash hider and shatter.
Bucking and nub are terrible, to the point Crosman did better.
