Hi guys

I am putting together a BCM 11.5 MK2 upper. I ordered the upper with the MCMR-10 handguard.

I am thinking the MCM-R might have been a mistake. The handguard is way to thin for my preferences. I think a combination the MCMR-10, the steep angle of the BCM grip, and the B5 systems Bravo Stock, have put the line of sight way off. It almost feels like I can't get my eye over far enough for a proper alignment without exaggerating my lean. Even when I do, it feels like the rifle is pointing at an upper angle. I don't know if this makes sense? Suffice to say, the ergonomics feel way off.

I was wondering if you guys have any suggestions?

Would adding M-LOK rail covers to add girth to the handguard help? If so do you have my recommendations?

You might try a higher optic mount, for one. As for Mlok rails, check out Daydream Defense with their KAC-inspired ribbed rail covers. Attached File

I've got Griffin Armament panels on one gun and they're pretty substantial.  They're perfect on that particular gun.
