Fighting Cat Front Assembly for G&P WA KA M4 Series Airsoft GBB Rifles

"This works PERFECTLY if your system is a WA gas system, I have an S&T GBB with a full metal receiver. The one with Colt trademarks. The holes are exactly where there need to be for the hopup and work just the same as my stock barrel.

Lol bad news was my first one came with the rail assembly missing. No problem, called evike and they got it replaced free of charge. They give typically around 45 days. One time gave me a little longer.

Anyway, the innerbarrel may not seem to fit, but you just have to make sure that its lined up, and push a little hard and if anything keeps your barrel completely stationary.
I put my AK suppressor on instead of the smaller one (it comes in multiple pieces and you can unscrew the suppressor) and it made my m4 look like an m4/AS val hybrid lol


Pros:
Worked with a different suppressor (but could also strip both barrel and supprs.. because the threads are slightly a hair of a size different.)
Very solid
Compact
Easy to install

Cons:
You have to take most of it off to access the hopup. That kind of sucks.

"They did a really bad job of gluing a big ugly orange tip into place, and let the glue drip all over the body of the supressor.....disappointed.......I don’t know what the last review was talking about with the hop up. The window was in the 4” barrel, but the outer barrel is a 14mm+ thread.....Grrrrr..

"Well not very happy with this for one main reason that makes this entire assembly pointless.

The outer barrel that fits into/through the upper receiver, where the hopup will sit, isn't grooved. What's that do? It makes your hop up twist, slide back and forth, and ultimately doesn't hold your hop up into place like it should. This creates several problems. First and worst is every time the nozzle pulls back and fourth, the hop up moves with it, vs' the hop up staying put. Also,, the hop up twisting not only prompts difficult mag changes, but the slight amount of twist (once mag is seated) prompts inaccuracy. Sure in cqb settings you aren't typically worried about accuracy past 100 feet. But still.

Also in my G&P VLTOR upper receiver, the outter barrel sits slightly left from the RIS. The suppressor end threads to the outer barrel until it is firmly seated about 1/8th of an inch into the RIS. Because of this misalignment, the suppressor won't seat into the RIS properly. The rest of it is a decent design. THe barrel nut has a double barrel nut, that the RIS then threads into. THe double barrel nut design makes it easy to have the RIS sit perfectly verticle like it should. If it doesn't, you can adjust it.

Ultimately because of the fact that it won't even hold the hop up, at all, I am forced to either replace the outer barrel and hope the replacement barrel is the same length to fit the flow of the suppressor position, or replace the entire thing completely. I.E. this set up has been rendered useless. Recommend you try a different one!
