Nerf Longshot Full-Length Pusher Breech

thingiverse

People often ask if they can create a full-length pusher breech, especially for long-range shots, as an alternative to cutting brass for a sleeve breech. The bolt is designed with a lipless style that accommodates seven sixteenth by five sixteenth and three sixteenths o-rings for the pusher, while one and one eighth by fifteen sixteenth by three thirty seconds o-rings are used at the back. This design utilizes seventeen thirty-seconds of brass for the barrel. To assemble the breech piece, simply push it all the way in until it stops. I plan to rework the design to accommodate nine sixteenths of brass that telescopes into seventeen thirty-seconds.
