Compatibility of the UTG KeyMod HandGuard

The UTG Pro SuperSlim KeyMod rail is designed to be installed on a standard AR-15 upper receiver.  This handguard will not be able to be installed on redesigned or over-sized upper receivers.  The UTG Pro KeyMod rail has anti-rotation tabs that are designed to work with the standard specifications of an AR-15 upper receiver.


Due to the extended, 15” length of this AR-15 handguard, you will need to have a low profile gas block installed on your barrel, as the hand guard will not fit over the standard A2 front sight base.  This AR-15 HandGuard system is not compatible with piston driven AR-15 conversions.  The handguard was designed to clear standard AR-15 gas tubes.  Due to the SuperSlim design for enhanced user comfort, this hand guard is not compatible with barrels with a diameter exceeding 1”.


Enhanced Modularity

The KeyMod accessory mounting system is the next evolution in AR-15 modularity.  This system is a next generation advancement of the older Picatinny rail system.  The main advantage of the KeyMod system is that is significantly lighter, as well as much more comfortable for the shooter.  This 15” UTG Pro rail comes in at 12.1 ounces.  For a 15” AR-15 hand guard, this is very light. When compared to an older 15” Picatinny quad rail AR-15 handguard, you will see that the weight savings are rather significant.


In addition to the above, the UTG Pro AR-15 handguard has other features.  For instance, this rail system has 7 full-length KeyMod mounting sections.  As with other AR-15 handguard, the UTG PRO has KeyMod slots at the 3, 6, and 9 o’clock positions.  However, the UTG Pro offers 4 more full rail sections at offset, 45 degree locations.  This gives you even more options for mounting your accessories, and ensures that you are able to put them exactly where you want them to be.


Improved Ergonomics

The UTG Pro rail, combined with the KeyMod Rail system is extremely user friendly.  By doing away with the Picatinny rail system, the hand guard is much more appealing to handle.  The SuperSlim profile of this KeyMod HandGuard is extremely comfortable to hold on to.  By having this narrow profile, shooters are able to more easily assume a C-clamp or thumb over bore type grip, which is increasing in popularity.  Also, this slimmer profile is much appreciated by shooters with smaller hands.


In addition to minimizing the bulk, the gripping surface is also much more pleasant than Picatinny quad rails.  The Picatinny rails that were so popular many years ago were known for digging into your hand.  After a day of shooting an AR-15 with a quad rail, your hand would usually be left pretty beat up due to the aggressiveness of the Picatinny rails.  However, with the negative space mounting system of KeyMod, you are left with a smoother gripping surface.  There are no aggressive projections poking into your skin, leaving you with a much more enjoyable shooting experience. 


Built to be Tough

The AR-15 KeyMod rail system was built with hard use in mind.  The UTG Pro hand guard is machined from high-quality 6061-T6 aircraft grade aluminum.  Once machined, this aluminum is finished in a hard coat anodizing.  This anodizing gives the rail system its black color and also enhances its resistance to wear and corrosion. 


Easy Installation

The UTG Pro KeyMod Rail kit comes with several parts and tools to make installation easy.  The package includes a lock ring as well as a barrel nut and spacer.  No additional parts are needed for installation.  Also, the package includes a barrel nut adapter wrench that can be used with your torque wrench to ensure a proper installation.  For a complete detailed description of the installation procedure, please refer to the user manual
