The 2 on the left are the asc and LaRue. The difference is where the weld is (asc down the back and LaRue down the edge of the bolt catch rib). The middle pic is with an asc 6.8spc mag where it's folded and spot welded down the front (as in the right pic). The asc isn't as well built as the LaRue, but price difference is far apart ($92 vs $21) as both are 20 round mags. If asc made it like their 308win mags the coal could be as much as 2.340".
It's a national match free floated tube already. I bought it from a guy who used it at Camp Perry for a few matches. He guaranteed it to shoot 1/2 MOA as is because he's done it numerous times. He told me he took 2nd place with it. So with that said, I don't believe I'm handicapped at all with the current handguard that's on it. 1/2 MOA at 600 yards is 3" groups. And that's with a heaver trigger 5.5# I want to say he told me, and a 4x scope or whatever their rules are. Plenty good for me the way it sits. I've got a lighter trigger and a 14x scope, so I should be able to come pretty close to that. Don't plan on throwing a bunch more money into it as it's more just a range toy and truck gun anyway.
Ok, that all makes sense now. Ya I'm not spending $90 on a mag either. Cavity back bullets is suppose to have some modified mags PRI I think that you can get out further, but they're out of stock most of the time. I think they're around $45-50 also. I can't remember how far you can get out with them but I want to say it's around 2.36" maybe?
