    Foregrip/fingerstop gas block in the way, M-Lok

    Finishing up my first SBR. 11.5 BCM upper M-Lok. The gas block is right at the spot where I want to mount my fingerstop/foregrip. Foward or behind and feels odd. Is there a offset type of grip? Is this the 11.5" hazards or drawback of M-Lok and I should of went QRF? Lol..

    Its a common drawback of many MLOK rails trying to be as skinny as possible, and ending with an ID similar to the OD of non-indexing barrel nuts that have to fit under a gas tube. Would it fit if you trimmed the screws that go through the T-Nut?

    It's definitely a drawback to M-LOK, I'd consider looking into QRF.

    I had the same problem with a M-Lok handguard and a mid length gas block. My Magpul AFG screws would hit the gas block in my desired position. I solved it by going to Centurion Arms M-Lok rail covers. They're long enough to span the distance fore and aft of the gas block, and grippy enough that I now don't need a foregrip/handstop. I used two 3 packs of the rail covers. 2 per side and 2 on the bottom. YMMV

    I freakin HATE M-lok. It's like the South Park of mounting systems... a parody of gun industry stupidity that never quits. I love my QRF rail.

    This doesn't happen with 1913 rails.

    I had the same issue on one of mine, and i was able to dremmel down the bolt so it fit under the gas block. Not sure how much room you have under there, but if it's just that the screws are too long, you may give that a try.

    I had the same issue on my 16" mid-length with a 15" Centurion MLok and a Arisaka finger stop, I ended switching to a KAG and putting it behind the gas block.

    The problem there is it can be very close and impact upon firing due to barrel whip.
