This kit includes an ABS 3d printed threaded adapter, thread cap, and threaded silencer. The adapter was designed exclusively for the Crosman 1077 RepeatAir. The silencer and thread cap are the same that are used on our M4-177 silencer kit. The silencer has 7 internal cone-shaped baffles. All the parts are 3d printed in the US and ship same or next business day.
Installation is simple. You’ll need a hammer to remove the front sight post/barrel cap. Hammer off the cap. Align the adapter with the tube from which the cap was removed. Make sure the barrel is aligned with the thru hole in the adapter and the sight post of the adapter is aligned with the slot in the tube. Insert it by hand, ensuring proper alignment. Tap it in with a hammer the rest of the way.
