Took 20 minutes with an armorers wrench, snap ring pliers, a torque wrench, an upper clamp and a vice to remove the floppy delta ring style plastics. Metal barrel nut clamps just roll on and then the hand guard is simply slid onto the rifle. No side to side roll or crushing/compression when gripped tightly. Very rigid for being such light and thin aluminum.

Evolution EX Series 7" Picatinny

Extremely strong handgaurd. This handgaurd fits tight and has no play in it. I definitely recommend this handgaurd if you want a strong free floating handgaurd that fits on factory barrel nut. I can use the factory front M4 front site with no interference.

12" Evo EX Rail

I love the rail. It's light weight and easy to put on especially being new to the AR platform. The top rail lines up perfectly and the accessories are easy to put on. It's a little tricky with the 12" barrel trying to put the verticle grip mount in the middle of the rail because of the length but it wasn't that bad. I plan to try their other rails in future builds.
