ARCA Pistol Zeroer
Edit: I guess team Big Sandbag and Bench™ doesn't like mobile zeroing doohickeys. Bummer.
After getting served an ad for PRSS' ARCA Pistol Rest, I made my own. Note that theirs is way more adjustable, and it actually has a notch for the light or frame to rest in.
Way easier to carry around and zero with, versus finding a bench to drop your bag on.
For me, zeroing or reconfirming a (compensated, usually) pistol off a bag/rest has always introduced a bunch of failures to feed and eject. Clamping the pistol directly into the tripod's ARCA/pic combo head results in it slipping out of the clamp if you don't hit a rail slot.
Got a new optic, decided to make this ARCA Zeroer V3 FINALv2. Used a spare ARCA mount, some wood, and some foam. The foam is pinned on top of dowels, so it can be removed for larger handguns, or a small bag.
Could I have cut a notch into the scrap walnut? Yeah. But then it wouldn't be worth posting on D-I-Why gun reddits.
