I have a A2 model carrying handle and was thinking of putting a low power scope on it since my old eyes ain't what they used to be.

My rifle is a Bushmaster M-4A2 Type with 14.5" bbl., thinking of mounting a Leupold VX-II 1-4x20 on it for hunting groundhogs ect. at ranges from 25-200yds.

Can anyone give me any info on these A.R.M.S. #2 base? ie: Are they secure/stay tight mounted on the carrying handle, do they retain zero after taking off and putting them back on again, are they worth a damn in general?

There are a couple of problems with this style carry handle mount.

- They raise the scope so high that it's hard to get a good cheekweld and still see through the scope.

- Return to zero can be iffy. Some people get around this by bedding the mount to the handle.

- The ARMS #2 isn't true Picatinny spec - the slot spacing is wrong, and the flexibility is a bit limited. They make an extended version that appears to be Picatinny spec, but I haven't actually measured one.

A better bet may be to put a non-magnified optic (Eotech/Holosight, red dot, etc) on an A2 gooseneck mount, which lets you both co-witness (depending on the optic) and keep a good cheekweld. It's good for aging eyes, but there's no magnification, of course.

Another option is a railed handguard with a scout scope. You'd want a very solid railed handguard for that, as some tend to shift.

My ARMS #2 stayed secure while I used it to get groups, but it was on a .22 upper, so there was little recoil. This is it with a Leupold 4-12x40 in a couple of low Leupold QRW mounts. You can see how high it is.

Here's the same gun with an aimpoint clone on a railed handguard. This works very well for me as my eyes go old on me, but again, recoil is light.

Ok Thanks! Thats what I needed to know.

Yea I can see where height might be a problem.
