Training with my Mossberg 500 was never fun. The recoil is so violent I swear its loosed a couple of teeth. So i ordered this to reduce the wear & tear on my old bones. I'm no expert nor am I a rookie when it comes to upgrades, but the instruction provided with this product SUCK! the only this resembling assembly instructions was a small exploded diagram that didn't show all the parts. Even the online video skips through the part I was having issues with. provided with the kit is a pan head screw with a square nut....WTF couldn't figure out where it went. the adapter IS NOT tapped for a screw, unlike 99.9999% of all other adapters or eve AR15 lowers. I finally figured out that you have to balance the square nut in the slot on the adapter, then slide the pistol grip over it the try to get the screw to start on the nut. Be advised the product is good, instructions suck



What a difference! Makes shooting anything a pleasure. OO, slugs, trap loads. Easy to install. Instructions aren’t included unless you consider a diagram instructions, but the info is online primarily Mesa Tactical’s website since it’s their adapter and Kynshots buffer. Just search, but it’s all kind of self explanatory. I’m impressed. I wouldn’t own a shotgun without one!
