and, trust me , you DON'T want one- if you have to mount that gun in a hurry, it ADDS to the deployment time- i have a bm59 stock fitted to mine and not only does it rob you of the space to fit your goodies, but it recoils like the devil with heavier bullets and just shoves into your shoulder like the old mk2 sten- with mine you have to swing the lower arm into place, lock it, then push the button and swing the stock into place- it's a TRUE FOLDER, not a TELESCOPIC, like the ones used on the m4 carbine series- the ONLY advantage is that it drops about 8 inches( and i'm guessing, i'm not going to go and drag it out of the safe) from the o/a length
mof i leave mine locked ( the lower arm) most of the time so all you have to do is punch the button and swing the arm in place;
there's also NO CHEEK PIECE- ie it's just 2 steel rods on a hinge and buttplate- pull up bm59 for a picture
