Disappointed to hear that, but at least I know not to waste my money on it.I have a keymod HG from evike (in addition to the WE MSK and the Nexus Tactical CL-3) and can attest it is garbage. The other two are solid.
I was going to try to resell it to get my money back but I can't bring myself to put it up for sale like it would hold up on a real rifle. So I'm eating the cost.
Right here, vvvThis. Who is RPM?? Any pics of said rail floating around out there?
The front locks up fine, the rear conflicts with the ears that hold the barrel wrench, even if you remove the barrel wrench you still have to radius the mount to clear the ears of the QD ring - If you have the non qd trunion it would fit just fine and then you have a very slim, very light, very cheap option - they are 25 bucks right now so you could go through 10 and break even compared to most others - they are as durable as they need to be for range and general use - if you want to use a hammer on one, maybe you own the wrong type of weapon. They do get hot because of how narrow they are so use gloves. You can cerakote it for some increased resistance to heat, maybe even spray the barrel or use reflective tape on the inside but it's going to get hot.From what I read, they said it would fit but you can't use the barrel wrench. YMMV
