About this 3D model

I was frustrated with a single-round loader I had purchased - it would rock, causing the front to ride high and the rear to fail to engage the bolt catch. You can see the problem in the photo provided: the front of the insert fails to catch the magazine's lips. Instead of printing an insert, I recreated the entire follower as a single-piece replacement. It has a nicely firm engagement of the bolt catch, and does not rock forward causes any interference with the bolt as it travels forward. By far the best solution. Bob Sleds are expensive, and the aluminum insert option has its own issues. Print guide: no supports .12 line height 3 walls 5 top/bottom layers I printed in PETG, but pretty much any filament will work. Print pieces with flat sides down. I made some pegs for alignment, but you don't really need them during glue up. You actually don't even need to glue the pieces together, the magazine spring will keep everything together.
