I had had this conversion kit on my 870 for years! It's works fantastic, and has made my 870 conversion bullpup prob my favorite shotgun to shoot. Never a problem, I personally like the trigger mechanics and pull pressure. Buy it you will 100% be happy w it.

This is a fantastic product and BUDS makes it affordable and easily available! Takes 10 inches off your standard police Remington 870 and makes it very compact and navigable for home defense or clearing rooms.
