EMG "BRAVO" Slimline Retractable Stock for M4 Series Airsoft Rifles (Type: Compact w/ Buffer Tube / Black)

"Not for KWA SR7. The stock will fit any buffer tube but using the supplied shorter buffer tube will not hold or fit to the KWA.

"ultra compact stock for any cqb build but the battery space is extremely small....perfect fit on a A&K m249 buffer tube adapter with no wobble

"Only the compact version has a battery compartment

"I got one of these on a emg helios slr rifle works aeg I purchased a while back, I liked it so much that I decided to pick up another for a different build I was doing.
the big thing that I think sets this stock apart from others is that its not a standard crane stock.
I have, in all honesty, never liked crane stocks, they look unrealistic to me, and are a little bulky. this is thinner and shorter that a normal stock, you can fit a single cell of a tri cell lipo on either side, but thats about it, and honestly, thats stretching it dependent on the mah of your battery, personally, just stick to buffer tube stick lipos, life is easier when you only have one set of wires to manage.
it is also shorter than normal, by allot, with it maxed it out, it gives me the perfect length of pull, and I typically run my stocks 2 or 3 clicks out.
I also love how easy it is to get the stock open and closed, just pinch the two tabs and off comes the butt, swap batteries and line up the tabs and smack it on with your fist.
biggest complaint I have with this stock is that it is very loose, it was loose on the slr, and loose on every other rifle I put it on, it creates allot of wobble and noise, I remedied this with electrical tape but that is the only disappointing things about this stock, for that reason I am rating it 4 stars.
but I would absolutely recommend it, I will probably pick up another one in the future

"Good size and feel, on the smaller side, but great cosmetically, it is a bit wobbly though, but it fits the price point.
