eXcise  (verb)

To remove by cutting.

The eXcise Optimized handguard series is designed to give the end user the perfect blend of modularity and weight reduction, while maintaining excellent strength and rigidity. By removing material in strategic areas, we were able to retain all of the most frequently used MLOK mounting locations while eliminating mass wherever possible. Nitrided steel QD inserts are included towards the rear for a bombproof connection between the handguard and your sling. Vented ports between the picatinny rails promote air flow, and the triangulated eXcise pattern directs stress around the strongest parts of the handguard. The eXcise Optimized handguards have everything you need, right where you need it, and absolutely nothing else.

Our clamping system is another feature that sets our handguards apart from the competition. The Retention Plate is made from nitrided and heat treated 4140 steel and the barrel nut is made from 7075-T6 aluminum. The retention plate and barrel nut physically key together to prevent the handguard from slipping forward under extreme use or recoil. The 18-8 black oxide clamping screws thread into the Retention Plate for a solid steel on steel connection. There's no aluminum threads to strip or helicoils to pull out, and the Retention Plate design helps to minimize the potential of over tightening the clamping screws.

A note from Phillip: Due to the slim nature of our handguard, it is not compatible with any aftermarket piston kit or with any piston operated AR variant, and may not be compatible with some clamp on gas blocks. A low profile set screw gas block is highly recommended. Use of the integral QD sockets are not compatible with bull barrels or barrels that are full thickness directly behind the QD socket.
