Maddie's 22

thingiverse

This is a remix from mulitple sources. 1522 lower from defcad, upper from AWCY? You will need to notch the handgaurd to interlock with the lower. Do this after you tighten the handguard screws almost all the way, mark and trim. The barrel nut is from the tubee 22 files. Factory bolt stop should fit. I printed a bolt stop because parts arent available but its too flexible to work without the mag to hold it. You will need to trim the lower at the rear of the magwell to clear the follower. The magwell spacer is for the front opening of the magwell if the mags are too loose. Print the spacer and plastic weld it in place. Works with a cmmg conversion kit, I used a dedicated bolt. Factory SW15/22 mags. The pic rail mount of the stock adaptor was left intentionally long. The pic rail on the mount is not dimensionally perfect, you will be going for an interference fit between the adaptor and upper. Get it really close the tap the adaptor on, after a pin hole can be drilled through both sides and a roll pin inserted. The newest bolt stop actually works well
