quick mrp questions

does anyone have the weight of a standard 16" mrp upper and the weight of the mrp piston variant?

also how wide the forend is?
thanks

I dont have numbers for you but this may at least give you a visual indication of how wide the forearm is.

Scroll down to the MRP piece.

From the brochures:
D.I. CQB16 6.8 lbs
Piston CQBPS16 7.3 lbs

(complete weapons, empty – since the op system is the difference i imagine the weight diff applies to uppers as well)
