Restock on 20rd MRX magazines for MRA Renegade Rifles

[Gumboots]

Can MRA and BCL come out with a 20rnd for the 7.62 already? Tired of being a second class citizen.

Do you know if the last-round bolt catch works with these magazines?

Update. I got the bolt catch to work on an empty mag.

Removed a little material at the top inside surface of the spine that is raised to stop the follower from moving all the way up and making contact with the lips.

Then I replaced the follower with a CAA 10/20rd pistol mag follower or an Alberta Tactical 10/20rd pistol mag follower. That mod makes the bolt catch engage when empty.

I tried Magpul Pmag followers and they are slightly too short lengthwise. Plastic USGI followers might work after significant material removal as they are too wide in the front end. One could also try putting a screw into the back of the original follower or trying to add some material to trip the bolt catch.

In the end if you have some of these old 10/20mags laying around give this a try. I'm happy with the results.

Note in the pics the arrow points to the area of the spine that need filed down on the inside to match the lower thickness of the spine and circled are the front and rear tails of the follower need shortened as they are originally long for limiting to 10rds. you will also see the areas of the back of the spine, mag rear surface thinning, to allow smooth insert and drop free as well as elimination of bolt carrier rub on the lips by working down the lips carefully with a file.
