Product Information:
I can't recommend this item enough. I used it in a G&G GR15 CQB Raider with a Mad Bull python tight bore, a Systema bucking and a Shredder's Concave Spacer. Wow. The results were immediate and dramatic. Have not had one mis-feed yet (I was missing around 1 out every 10 shots). The distance looks to be a good 50 feet more, the speed increased by around 10fps (from 410 to 420) and the accuracy is just night and day different. Is it worth the $40? YES. Get it. Now. You will thank me.

Strong but light CNC, will not warp over time. Seals way better to air nozzle and gearbox. Perfect fit (not too tight or loose) around the barrel. Better accuracy, speed and feeding.

It does not come with instructions or a tension spring. The arm goes in the top and the pin slides through like normal hop ups. Then the rubber o ring slides over the air nozzle hole into the groove closest to the hop up body. The big wheel slides over that, making sure the tab from the arm fits in the grove on the wheel. The o ring keeps the wheel from turning on its own. Then the c ring clamp snaps on the hold the wheel in place. Pretty simple but instructions would still be nice.
