I've pretty much setteled on putting a ARMS #38-ex on my A3. What type or types of ARMS Aimpoint mounts could I use to co-witness in the lower part of my ML2. (Standard front site)
Thanks.

The one and only, ARMS #22M68, no spacer needed.

Nice! Where is the front sight when looking though the aimpoint? Also did you have to file you handgaurds?

I concur.
If you are using a Swan Sleeve or extended rail-ARMS 22 M68 no spacer is the way to go.

Pic above was from one of the fellas here, but Mine is mounted same way on a ARMS S.I.R. #45.

The M68 places the ML/ML2 at co-witness height, just where ya want it.

If you have M4 handguards (newer oval type) you'll need to buzz the rear 1/2" or so of them, very minorly (mostly level the tiny ribs on the last segment of HG, for the #38EX) to have clearance for the #38EX. FWIW I have an #38 SuperEX over M4 Handguards, (requires more Dremel work) and the pic above has Surefire handguards, IIRC with mod made for the EX to clear them.

BTW, you can use that old standard HG over a M4 type lower and have no clearance problems.
