the ez22 bolt with an autotrip added and an optional updated hammer pusher, please let me know if the auto trip needs to be moved forward or backward. This bolt will need to be used with a lower that has a buffer tube cutout
UPDATE: heard that the autotrip was too far back so I made anew different versions moving it up 3mm, 5mm, and 7mm. hopefully one of these will be right where it needs to be but if not let me know and ill update again
what will hopefully become the final barrel update for the ez22. this updated body should allow for swapping out worn feed ramps easily, as well as now having a centering notch to keep the barrel aligned when assembling
Update 1: added wings to the ramp to try to prevent heat warp when barrel is fully hot, unfortunately this change will make print setting slightly more important
Update 2: I added a new style feed ramp that fits against the mag more snuggly and has a milder angle. this one is more hollow point friendly
Update 3: i found the way the wings attached to the body of the ramp was weak and at risk of breaking if there was an obd, this attempts to fix that as well as further optimizing the ramp angle
update 4: added an option for 7.9mm barrel liners
update 5: widened option for 7.9mm liners
update 6: removed bloat files. changed body to make jb welding the liner much easier. added version for 11.3 asb with a built in ramp, should be easy to mod for weird sized barrel liners
update 7: further optimized the ramp
this file may be changed or updated in the near future.
once this goes through testing it will be part of the 0.92 update
very early concept for a side loading ar22, as is everything has a pretty ugly fit and finish but should be functional. when the ez22 gets closer to where i want it, i will start applying all the updates to this version
designed to shoot standard velocity 22lr, shooting ammo that is too hot will result in burst cases.
an easy to print, easy to build 22lr pdw. Incredibly ergonomic, reliable and comfortable to shoot
core design is FINAL, will see attachment updates
update: 1/16/23 fixed slight scaling issue with the cheek rest
update: 1/20/23 fixed buffer guide model (spring channel was too small)
update: 1/30/23 added a weighted bolt pusher for shooting extra hot ammo(bolt will still wear prematurely but this helps prevent bulged cases)
update: 8/20/2023 assembly vid
lovingly named by r/fosscad this is currently only known to work with the hipoint jhp. If you comment how far the rail and bolt need to be moved up/down to fit a different model ill update this to work with it as well
updated to include step files
an ez to print and ez to build ar15 bolt designed to shoot 22lr, tested and working but currently trying to get ejections more consistent.
README IS MISSING INFO-if no buffer tube will be used print upper with threads up, picatinny towards you and located at 0,0,0. add support blocker location should be -1,30,76 and scaling should be 6mmx20mmx65mm. with the support blocker highlighted click "per model settings"->"modify settings for overlaps"->"cutting mesh"->"select settings"->check box for wall line count, top layers, bottom layers, and infill density->click close-> now change all those support blocker settings to 0
this info is relevant for any ar22 barrel liner install, but printed parts and specifics are for use with the ez22 upper and bolt available on my odysee. version 0.91 and the side loading version will be available soon but a broken printer has slowed me down
a silencer designed to be slid on jb welded in place to the barrel liner of an ez22. I haven't tested it because i'm a good Christian boy but it should work very well. liner side is 108mm deep
