Please make sure you checkout the list of non-compatible stocks when you purchase a Habu Mod-1 or Habu Mod-2.




To Operate HABU Mod 2 for AR-10  simply rack it like you would a pistol slide. With your dominant hand, trigger finger indexed outside of the trigger guard, take your non-dominate hand with your thumb to the rear, in one motion grasp, pull to the rear and release.

HABU increases target re-engagement speed after a malfunction because HABU enables the shooter:
1. Faster, more robust malfunction clearing with less effort while keeping the target in your optic and the rifle on your shoulder rather than dropping the rifle from your shoulder to operate other charging handles. HABU allows the shooter to use their major motor skills to fully torque and charge the charging handle in the right direction rather than torquing the mechanism to the right or left.

2. By eliminating the gasses going into the shooters face using suppressors or not, the shooter can shave approximately 1.5 seconds re- their target clearly.
Both of the above benefits can shave between a full 2 – 3 seconds off your re-engagement time which is critical for Military and Law Enforcement Entry Teams, Competitive shooters and varmint hunters alike!

The HABU was designed by veterans who saw a need for an integral cheek riser for the AR. This was needed to better align the shooters eye with magnified optics with short eye reliefs. The Army and Marine Corps both issue magnified optics to their ground troops. For many years it has been impossible for most shooters to attain a proper sight picture without goose-necking, until now. solves this issue and will provide the solution that many asked for, yet only Falcon 37 delivered.

Why HABU Mod 2 is a “Must Have” AR part.
By combining the charging handle and cheek rest Mod 1 not only accelerates and improves operation of the AR platform, it looks BAD-ASS… like it belongs there! HABU Mod 2’s gripping surface works just as well under wet, muddy or bloody conditions.

Falcon 37 Inc. wanted to create an effective, ergonomic cheek rest device that would work with adjustable stocks in any position; without stock modifications, allowing the shooter to keep the rifle on his shoulder and indexing ones cheek in the proper position using optics. Having proper cheek weld on the weapon minimizes the time the shooter spends “chasing the red dot or reticle” with their eye.

Non Compatible Stocks

Falcon 37 designed HABU® Mods 1 and 2 to operate on as many of the currently used stocks as possible but we had to draw the line somewhere. While these are good stocks, HABU® is not fully compatible with these stocks without modifications.

Daniel Defense stocks with rubberized siding.

Hogue stocks with rubberized over mold

Maxim CQB stock

In this photo of the CQB stock fully collapsed, the arrow points to the location where if the stock was fully extended to the rear, HABU® might cause a short stroke. HABU® works well in the other 3 positions.

Note: For now, our HABU® Mod 2’s are shipping with the Mod 1 polymer part to save us money on new tooling and pass the savings on to our valued customers. The HABU® Mod 1 polymer part is completely interchangeable with HABU® Mod 2.

*The product page for the 7.62 charging handles lists the models known to be compatible with our charging handle. Unlike the milspec AR15 platform, no such standard exists for the AR10s, and there are dozens of variances between manufacturers. Since AR10 models change constantly, it may work on your weapon, though we cannot guarantee fitment.

What we do guarantee is Falcon 37’s 100% Lifetime Satisfaction Guarantee. We got your back. If your rifle is not on this list and HABU® Mod 2 is not compatible with your bolt carrier group, we’ll refund your money.
