Mag mods

[LRRPF52]

I just counted all my Grendel mags, which include:

2000s-era CProducts 4, 10, and 17rd straight body mags (the 17rd straight body mag was never supposed to be produced or sold, but was done anyway by CProducts after they didn’t meet AA reliability specs)
2013-2017 Elanders (10rd, 17rd, and 25rd)
Amend2 Polymer 10rd
20teens ASC 25rd
2020 purchased ASC 25rd

I haven’t modified any of them. I shoot mostly the 17rd and 25rd mags, with the 10rd Amend2 here and there.

I do modify my feed ramps with de-edging, blending, and polishing. I also make sure the ejectors don’t bind against right side presentation feed cartridges with a chamfer.

If the mags don’t have the correct feed lip and follower geometry, I’m not interested in them.

There was one I had to modify for a guy who I did a MARPAT Desert Cerakote job for back in 2011.

I didn’t realize one of the feed lips was not symmetrical until I had already began Cerakote work on it.



Other than that, I’ver never messed with AR Grendel magazine mods. I did window my Howa’s little polymer mag to allow longer COL.

I shoot the Grendels a lot, and have multiple different types of receiver sets and magazine combos to use.

I like the 25rd ASC mags the most in the 12”, unless shooting off a bench that doesn’t allow clearance, then I use the 10rd or 17rd mags.
