Modify Baton Ryusoku Flat Hopup Bucking for Airsoft AEGs (Model: Soft)

If you have a G&G or any other brand of gun or hop unit that uses a standard sleeve to stabilize the barrel inside the hop unit. The part that goes in front of the bucking on the barrel, that doesn't have a shoulder to prevent it from being pushed inward, you will have feeding issues because the pressure of the spring or o-ring pushing on this sleeve will push the bucking back into the feed tube. This is because there is nothing inside the bucking to hold it in place except the ridge that centers it.

So either get a sleeve with a shoulder or try a different bucking unit.

I put a 4UANTUM flat bucking and nub in another G&G build with 0 issues.
It has a built in bump like most other bucking that helps keep it from sliding down the barrel and blocking the passage.

oryou can shave it like someone else did but I think that would cause other issues.

It did shoot well but I wound up putting the green G&G bucking back in and left the flat nub. Seems to be doing very well at 100'.

"Although I'm happy with some of Modify's other products, this HARD bucking (color: black) was extremely soft. I don't think it's sufficiently durable for use in any of my airsoft collection, whether the muzzle velocity is 300 fps or 500 fps. It is about the same softness as the stock soft bucking that I was looking to replace.

"I just got the thing and put it in my gun and a bb snagged it and ripped it. I was using .20 like it said to. The nub was a pain to put in as well. I would not get this it was a waste of money. If u flat hop your gun let someone in evike do it for u. I give it one star cause it couldn't get through one mag.
