Building a .458 SOCOM AR

[hk_shootr]

I’m too ashamed to tell you how much I paid for them but when I saw them, I just had to have them.

We already know.......I’ve thought about buying some myself.

My best accuracy was 30.9 H110.

I've seen some posts and a vid of a guy that did some filing on a PMAG to get it to feed properly. I have 1 I'm going to experiment on. If it doesn't work I'll get the Lancer mags. I'd just like to have the 13 rounds that would fit into a 40. No need for it, just want!

Do you get the PMag to work?

Nice job on the build.

Thanks.
I never did try the PMAG. I just ended up buy some CMMG-modified Lancer mags. https://www.cmmginc.com/product/maga...m-lancer-10rd/

A bullet that big will create more gaps than it fills

Very cool and that's pretty fast shipping! . So what's the plan? Purpose-wise? Just doing a fun project build or is it filling a gap?

A great deal of matte rail needs to be removed to get a PMag to feed acceptably.
Slightly modified Lancers have worked well for me.

What is "matte rail", typo on material perhaps? It makes sense to use Lancers in a .458, PMag & GI = 5.56. I was just curious if he got it to reliably work.

Yes, typo, was suppos3d to read “material”

Just making sure it wasn't a learning opportunity.

If you didn't see my 1st page post, my modified PMags run great. I'm not sure what gen Pmag has that little V guide in the front. File/sand it to a downward angle & 300-350 gr hollow points feed 100%. The longer heavy >410 grain bullets don't even fit in that gen PMag due to that V. Those bullets work fine in regular STANAG mags.
