Quick Tip: Mounting M-LOK Accessories Next to the Gas Block
This quick tip from Brownells addresses a common mistake when mounting M-LOK accessories on AR-15 handguards, specifically near the gas block. Improper mounting can cause the accessory to press against the gas block, creating tension on the barrel and significantly degrading firearm accuracy. The solution involves ensuring the accessory is mounted in a slot that allows the barrel to remain free-floated, or, if necessary, modifying the accessory's mounting screw.
