I am mounting an Aimpoint, in an ARMS 22M68, on a Colt A3 upper.  What are the pros/cons of using an ARMS #40 vs. ARMS #38?

If you use an ARMS #38, get the #38ex or the #38S-ex. That will allow you to more forward mount the aimpiont and that is a real advantage. Forward mounting allows for quicker sight acquisition, assists in two eye open shooting, quicker focus, clears your field of view...

Other than that, some folks think using a sleeve protects the flat top of the upper. I can see the point, but I dont know how crucial that is.

Thanks new-arguy.  I appreciate the input.

There's no way I'd pay that much for a sleeve.  If I couldn't find a smokin' deal somewhere, I'd forego the sleeve.  I'm not that worried about protecting the flattop.  For me it's about moving the Aimpoint up for co-witness, moving it forward, and having an integral BUIS.  

Speaking of smokin' deals, that sounds like a great price for an upper.  Where would I find it?

That's the price on RRA's web site.  You can probably find them even cheaper than that.

Hmmmmm.  Can you tell I haven't been in the market for an upper lately?

Maybe I should clarify--that's for the receiver only.  No barrel, bolt, etc.  When you say "upper" you usually mean the upper half, not just the receiver.

Right.  We were on the same page.  Thanks for the clarification though.  Nothing beats clear communication.

"I shoot, then move, and what's that other thing...?"

Thanks for the input folks.
