OMG. thats it in a nutshell. Great rail system. Full metal. Comes with ev erything u need to mount it. its just a PAIN IN THE ASS TO INSTALL. i literally spent 45 minutes trying to figure it out ( ya kno, because it doesnt come with instructions) anyway i ended up figuring it out. just go on youtube and search p90 rail install. i got all the screws to line up except the the top right screw. it stays on fine with no wobble even with that screw missing. ( i was surprised) Pretty long rails also. its like at least 4 inches in front of the flash hider so you are going to need a silencer if you dont want it to look stupid.
comes with all pieces to mount it
tons of rail space
looks godly on the p90
VERY VERY sturdy, no wobble at all
pain in the ass to install
needs a silencer to not look dumb (extra $$$)
