printed ar magazine (treat this as a beta test), personal prints made on a P1S
Update 1: Updated follower to V2, removed V1, and re-uploaded files.
Update 2: Tested fitment of PPA-CF mag body. V2 follower is tight and will need to be broken in. Once broken in, mag runs fine. see known issues 2
Update 3: Added 350 legend design (non tested). Updated follower stop 2mm lower, possible fix to feed lip breaking.
Update 4: -Shortened "Follower" by 2mm. This will allow full mags to be easily inserted.
-Loosen tolerances on "Follower" leads to smoother mag, and will not have to be broken in.
- The follower stop on "mag body" has been decreased by .5mm to keep the follower from hitting the feed lips. Follower may still hit the feed lips. it is a fine balance between last round bolt hold reliability and protecting feed lips.
- Removed material from the back rib from the top of "mag body". Noticed wear on the test article, not sure if this will affect strength. I will add material back if this is an issue.
-Known Issue 2, hopefully fixed with this update.
Troubleshooting: Print MAG BODY with 20° tilt forward. You will only need support on the bottom. Light sanding on the bottom recomended. Always print followers in PLA or PLA pro
Known issues: 1: Possible tolerance issues between AR brands. Mag should be close to 63.45x22.5mm for the mag well. Might decrease to 63.2x22.25mm to fit more platforms. Once more data is acquired, V2 MAG BODY will be released and a note will be added to the update section and this note will be removed.
2: PPA-CF feed lip broke while loading and unloading test. This could be because follower catch is not in tolerance, allowing additional stress on the right feed lip. PLA pro is still holding up. POSSIBLE FIXES: might increase the thickness of the feed lips by .25mm. Will experiment with different print orientations. The current is very horizontal, if needed, I will make a model with modeled in support. If so, I will have 2 models with and without support.
