M-Lok Fore-end compatible with JP heat dissipator?
I have a JP upper that I'm pretty happy with. The blend of adjustable gas, BCG, heat dissipator and brake is really a killer set-up for gaming. It is about 10 years old. I was looking at a new one and I'm not thrilled with the old style tube on the JPs and the new one isn't that much better. Looking for an easier and faster way to config the forend with stops and bipods and such. I'd like to go with an M-Lok, two things:
-I guess all M-Lok slots need a flat surface, so you'd never have a round tube, always some kind of 'stop-sign' extrusion?
- Are there any forends that have an ID of greater than 1.375? How would the flat sides measure into it?
I know the style is to go thinner with narrow diameter tubes.
1.375 is the OD of the heat dissipator for .75 and .65 barrels.
