||Great rail system! Truly "no modification needed" to the D-Ring like some other FF RIS systems.
Put these on my KWA M4 and made it look amazing.
--True Free float system. NO modification needed to D-ring or front sight post (unless you need more space for the rails in the case that you get these ones for an m4 length gun)
--Numbers on the rails showing how far apart they are. (Very cool)
--Got mine on sale (85$!!!)
--Simple to install (Not easy, simple :) Only requires 1 allen wrench an 1 flat head screwdriver.
--Didnt come with instructions (Box said "Use instruction manual" lol)
It was fine. Took like 20 mins to install. Very easy to figure out. there was only 10 screws.
-Pricy $$$ The Matrix rail systems are half the price. But if you have the money and want the best rails on the market, GET THESE.
-- Installing was meticulous. Some of the screws were very hard to get in because of the weird angle you have to screw them in with.
Besides the minor cons, this is THE BEST rail system ive ever had.
*NOTE* If you are getting this for an m4, you will have to remove the front sight post in order for this to fit. (Pop the 2 pins out from underneath it) If you have an m16 length gun, you are fine.
