❓ Drop-In M-LOK Handguard FAQs
Will these handguards fit a front sight post?
Yes. Drop-in M-LOK handguards are specifically designed to fit around A2 front sight bases (FSBs) with a standard delta ring.
Do I need any tools to install them?
Most drop-in handguards require no tools. You may need a handguard removal tool to compress the delta ring for easier install.
What’s the difference between carbine, mid, and rifle length?
-
Carbine: ~7" – most common on basic AR-15s
-
Mid-Length: ~9" – smoother recoil impulse
-
Rifle-Length: ~12" – optimal for 20” barrels
Are these handguards durable for hard use?
Absolutely. Brands like Magpul and UTG use reinforced polymer or aircraft-grade aluminum to ensure durability under combat and competition conditions.
