"This stock is built very well, and I love it overall. This one fits just fine on my GHK M4 V2, but there few issues that I noticed

- It doesn't have the "cheap" feel (Great Quality)
- Fits most of the M4 GBBR, as it should be
- Easily Adjustable
- Has the engrave? or logo? like the real ones
- Rubber butt pad feels good, it don't hurt without shirt on

- It is very hard to put it on, you have to pull down the small pin that is very hard to pull it
- Idk if others have this issue, but the stock won't retract fully on my GHK M4. It will retract fully but it won't make that "click" noise so if you pull the stock it will move freely until the "first" extension point, or the "second" extension point on the default buttstock.

I really wished if I could post the photo so I can show it to you guys but I still love this and I will continue to use this unless it breaks cuz it aint that big deal to me

"One of the most decent quality stocks money can buy. You cant go wrong if you pay only 37 bucks for it. Its a pretty sturdy polymer stock and its compatible with mil spec buffer tubes so its convenient. I do however feel like the rattle of the stock can be better and some parts can be reinforced for tougher abuse, but its an affordable entry level stock that will get the job done so I cant complain much.
