Did some horse trading and figured I would play around with this CAR. It's a RRA entry tactical with the tactical carry handle. If I remove this handle and put on the eotech & as expected the A2 is in the way.

Open sights line up good with this carry handle but worthless with the eotech on top. I noticed it also came with another thumb screw riser where you can place on top & see through to use the open sites. (pretty neat) It's the one on the upper right.

Good grief....by the time I get the eotech on top of this riser, I can rest my chin on the butt stock and have a perfect view of the holo. Talk about heads up..I bet the center of the eotech is 2" above the A2 front site.

I'm always open to goofing off for the fun of it but would you waste ammo sighting in or just go open sites till the dominator riser comes in??

Thanks and sorry for the weirdo question....kinda board.
