Installed but never used Butler Creek side folding stock for the Mossberg 500/590 series shotguns. The folder part can be taken off and only the pistol grip used if desired. Recoil pad as installed from the factory tames recoil and this unit has a nice lock up. I bought it new in the wrap and then installed it to see how it looked but it's a tad bit too short for me so I took it back off. I remember this stock being very hard to get, I was on back order for months so if you want it let me know...$70.00 shipped, which is less than I paid for it.
