I am very excited. As soon as my M4 upper gets here, I will have a nearly complete rifle. I got the ARMS 40, and the #22M68 also. The Aimpoint is a M2. All of this to go on my Oly lower. Thanks Wes, I'll be back for a light.

If I ever get a camera I will post pics.

Please let me know how well your Aimpoint® setup goes.

Hope you enjoy. I have exactly same setup.

Oh yes, don't forget to tighten the vertical bolt that holds your front rail portion. Mine didn't come fully tightened and my zero on Aimpoint changed.

Then I used a bit of loctite and it is now solid as rock. Shot well over 500 rounds (including rapid fire (20 rounds in less than 5 sec) test) and holding zero is no problem.

Oh yes did I say the barrel cools down really fast [:D]
