"Worked great for me. I put in a madbull tight bore and some flat hop. I can now shoot over 200 ft. Great hop up system.

"Not happy with the performance. Bought two to upgrade a King Arms M4 AEG and another M4. Neither unit worked in either weapon. I'd get one or two good shots then misfeeds and low compression shots (10' travel). Again, not happy with the performance of these units.

I haven't torn them apart to see if it's just the barrels, bucking or hop up units.
