"Very nice hopup works well. I have bought for multiple guns 2 Ak's, VSS and a Bizon

"This is my go to aftermarket hop up. The main point about this hop up is that it works with most mags, as opposed to other hop ups. The e&l hop up nozzle goes too far down and causes double feeding with certain mags. The cheap looking matrix/cyma one was awful; the nozzle was either too far back or forward (it was 5 years ago) and my mags couldn't fit into my ak cpw. Then the real sword nozzle is too short; it wouldn't active my rpk mag in my echo 1 rpk for feeding.

Anyway, when it comes to this hop up, it actually does what a hop up does. It will fit most mags and fits into a variety of guns and barrels. I had this a e&l gen 2, echo1 rpk, and echo1 contractor ak. Then it has this little circular extension in the back so the hop up seats flush with the gear box for proper feeding and air compression.

Also, yes there's no hole for the screw in the back of the hop up, but it honestly doesn't need a screw there. The plastic is large enough that it keeps it in place.

-Works with a variety of mags
-Works with a variety of guns
-Flawless feeding and accuracy

-False advertising since there's no hole for the back screw, but that's not needed.

Pro tip: Place a O-ring on the front screw where the slider is to prevent the slider from moving.

"Good upgrade for lct ak’s. It gives mags a much better positive connection when reloading.

The hop adjustment arm on mines needed to be filed down to actually make it move the arm Because it was too big to fit into the metal slots that it slides (the arm that you slide left or right to adjust the hop, not the actual nub arm)
