originally i had a cheapo 4x scope on my AR with a clark customs carbon FF tube. i saw some guys 3gun setup with a red dot mounted 45 off so i bought a cheapo rail section and a cheapo red dot and set it up. it worked fine for plinking but i decided to man up and buy a nice optic. Eotec went on and the other stuff came off. i love the Eotec but i found that sometimes the reticule gets washed out in the sun, and i dont like relying completely on batteries so i scored a deal on some MBUS. problem i had was that the rail sections on the tube were taller than the receiver. it looked ugly and was hard to zero. then i found PRI and all was well. the PRI tube is almost the same size as my clark tube. the rail is contured for the round tube and matches the receiver height almost perfect. also looks absolutly sweet. ordered up a 8.5" and a few 3" sections. i still wanted a 45 offset rail in case i go back to a scope because i like that setup. also mounted one for a flashlight (and to cover some holes lol) and may mount the last one underneath so i can mount a bipod or grip. i think it came out pretty nice anyway.
i will say i didnt get much help from PRI before ordering. sent a few questions and received short answers or links to the products i was already looking at. i do so hate to bother companies i want to throw money at but a little extra effort would be nice.
