Lightweight, ultra strong, slim and rigid free-floating NordLok handguard. It has unique contour that makes it ultra strong and versatile. NordLok contour makes handguard stronger than M-LOK and way stronger than KeyMod. Picatinny rail modules can be installed at every 15 mm / 0.6" compared to M-LOKs' 40 mm / 1.6" or KeyMods' 20 mm / 0.8".
 
Our NordLok handguards' outer diameter is only 40 mm / 1.6" to fit every shooters' hand for firm grip. Handguards' special contour ensures no hand slipping whatsoever, whether you grip it with bare hand or with a glove. Free-floating means the handguard does not touch the barrel and therefore does not negatively affect the accuracy of the rifle.
 
We have developed special barrel nut for our handguards (included with the handguard), that fits perfectly under gas tube allowing maximum tightening without the need to align it with upper receiver's gas hole. You will need special barrel nut wrench (NA-HG308-BNW, not included) to tighten the barrel nut.
 
Use picatinny rail modules (NA-HG-RNL, not included) to attach bipods or other accessories to the handguard. You can also attach our strong barrier stops (NA-HG-BSNL, not included) or Quick Detach Swivel Mounts (NA-HG-QDNL, not included) directly to NordLok contour.
 
Our NordLok handguards also accept direct attachment of most M-LOK accessories.
 
The channel for the gas tube is 12 mm / 0.47" wide, so it will not fit gas blocks with larger upper part (for example our side adjustable gas block). If planning to use our gas block, choose front adjustable or non-adjustable gas block.
