This Lower receiver nylon tipped set screw is designed to be used with lower receivers that are drilled and tapped with a 1/4"x28 threaded hole underneath the grip area. This tension screw eliminates receiver wobble and play by protruding up and placing tension on the upper receiver. Comes in varied batches of black or stainless steel, green or white nylon tip, and either 3/8" or 1/2" length. Any of the aforementioned variations will be equally effective.
Please note: The lower receiver must be threaded to accept these Tension Screws
