Great stock, but may require minor adjustments - Magpul Industries SGA Shotgun Stock for Mossberg 500/590/590A1

This is a very comfortable stock, with nice texturing, a recoil-absorbing butt pad, with one minor design flaw. After installing, the instructions note that you might have to loosen the stock to disassemble the firearm for cleaning. This is less than ideal because prying that snap-in plastic cover off the stock for several cleanings would inevitably lead to that plastic cover’s clip breaking due to the repeated stress of installation and removal over the shotgun’s life. Not only did my Mossberg’s trigger assembly get locked fully under the stock, but it put so much pressure on it that it was transferring that pressure to the pin that is removed to pull the trigger assembly out of the receiver. I used an xacto knife and a small rat tail file to slowly shave and smooth material out of the stock’s channel for the trigger assembly, checking fitment frequently. Once I could pop the trigger assembly past the outer plastic lip of the stock, a little 320 grit wet or dry sandpaper and a polish with Mother’s mag & aluminum wheel polish brought the plastic in the channel back to a factory-looking finish. Magpul should have suggested that to address fitment, or there should be a more durable way to attach the cover over the bolt that attaches the stock to the receiver.
