APS M870 Shell Toolkit

Update 30Apr2022: Added a functional Xpower compatible flower wad and Xpower compatible slug. print from TPU with no supports needed.

Update 02Feb2022: New choke, slugs, anti-tilt follower, and shell casing

Update 22May2021: Cap and Wad updated for superior reliability. Extenders and Choke added.

Notes about each part:

1.) Cap - RESIN PRINT - Should work for most APS shells. You may need to print at 99% or 101% depending on your shell tolerances. Should shatter as it leaves the barrel and press fit in most APS shells

2.) Wad - RESIN OR FDM - Works as intended. You don't "need" these but they help get you some solid fps. Guaranteed not to Squib.

3.) Shell Valve Tool - FDM - Use two m2x10mm bolts and thread them in. This helps remove the caps off the back if you ever need to swap out o-rings. Very useful to not cut your hands!

4a + 4b.) +1 and +2 shell cap extenders - FDM OR RESIN - Make sure to use a longer spring. Recommend using with the Anti-Tilt follower below.
