This thing is awesome. I use a 185mm Prometheus barrel with R-hop and my gun is unstoppable now and the Rhop allows for field ranges (120ft+)
-Easy maneuverability (I use my M4 as a backup now instead of my WE 1911 which broke on me)
-Just enough rail space
-Fits just fine on a G&P metal body
-No space for battery or wires inside rail. I use a pouch strapped to my rails to hold it all
-Price for such a little thing
-Pain in the butt if your gun is front wired. I had no choice since mine has no stock
1. Remove the two rings that come already screwed into the rail in the back.
2. Put the barrel into your receiver.
3. Take the nut that threads onto the receiver and screw it on as tight as you can (try both, one will work and the other won't).
4. Screw the rail onto this ring as tight as you can. A vertical grip is useful for this, or use a screwdriver and stick it through the holes in the rail and align it with your upper receiver.
5. Attach the suppressor.
Done! This worked for me just fine. Hasn't failed me yet. It's very sturdy and well worth it!!! Highly recommended if you play CQB or want a better secondary for your sniper loadout like I did.
