AR-15 10 round mag dimensional question

BobCat45 · June 30, 2015, 02:44 PM

If anyone here actually has a 10-round AR-15 magazine - not a blocked 20-round mag, but an actual 10-round - can you describe about how far it protrudes from the mag well when it is seated?

Thanks!

Very slight, less than 1/2 inch - actually just over 1/2 inch.

Not much, even though I live in a ban state I don't own any since I have a whole bunch of pre-ban 30rd mags. If given the option I would choose a blocked 20rd mag just for the ease of handling.

Anyways here is a photo of what it will look like.

Thanks!

In Service Rifle the 20-round mag does not get in the way of the sling, but I built a no-more-excuses Match Rifle and in prone, the match sling and the 20 round mag argue over space. Maybe it is the adjustable handstop, I don't know.

Anyway it sure looks like 10-round mags will alleviate the problem. As far as I can tell the 10s and 5s are the same external size - in MR they load 5 & 5 instead of 2 & 8 for sitting and prone rapid.

Thanks again, I'll get the 10-round magazines.
