Be prepared to get some sort of cheek piece. The face to stock weld on that setup has to SUCK.

Yeah, it does...
When I had the EO-Tech on my M1A, I made a "low-rent" cheek piece from an old mouse pad. I cut it in half and stacked the two pieces. I used rubber cement to hold them together and some black cloth tape to attach it to the rifle. It didn't look that great, but it worked OK.
I'm looking at a Blackhawk Tactical Cheek Pad that's adjustable for height. I think Quantico Arms has them...
It's gonna be a while before I can scrape up that kinda coin for that ACOG, though. Man, Trijicon is PROUD of those things! I might just opt for an Aimpoint or another EO-Tech...
In the mean time, I put an el-cheapo($30 @ Wal-Mart) BSA red dot sight on the M1A. Cheap, but it works...I've got a Smith Enterprise Tactical Scope Mount on my M1A, so I can still use the iron sights in case the BSA goes "Tango Uniform".
