4UAD SmartAirsoft 4UANTUM Friction Pro High-Performance Bucking for Airsoft AEGs

"My BBs disappear into the horizon, so I don't know how far I can go with it, but I know its more than 250 feet shooting 0.32g.

Stock E&L AK74 with this bucking and a Lambda 469mm barrel fires absolute lasers. My chrono results were 1J without variation some days ago with 0.32g bio Evike Tracers. I kept the stock hop unit.

However the initial few bbs were really wonky, like 0.7 to 0.9J, but after a few tens of BBs it dialed in.

Very happy with these results so far.

"I have a Arcturus AK12PE first Gen. I upgraded the hopup unit to the gen2 version and installed this bucking with a lambda smart .03 barrel. My hope was to shoot with .30bbs so I initially tested with 30s and bbs didn't go past 20 feet. Once I dropped down to .25 this bucking was shooting lasers and with great distance with hop still dialed at 0. Ive yet to try it with .28s but sofar with .25bbs I'm more than satisfied.

"Ive done R-hop, flat hop mods, etc.

To have something as a plug n play with the same results is astounding. This rubber is great and i am getting great range.

My build is a 15” Arcturus with a stock barrel (6.02) and lancer CNC hop up unit. I was having feeding issues with the lancer unit and some other bucking’s ( prommy purple worked great).

Im shooting at 1.45 -/+ 2fps on .20g using either .30g or .28g depending on, and I’m easily hitting an 6” circular target at 170ft about half the time.

It was never meant to be a DMR, and it isn’t but i am considering a x3 flip over magnifier

Overall the worst case scenario is you spend $12. But for me these are the only bucking i will be using now.
