The A3 Tactical Modular Folding Brace (MFB) is a great addition to your HK MP5/SP5 or clone. The MFB is designed to provide modularity in style, form, and function.  Various configurations are available to personalize the setup, and the modular system components can easily be configured to suit each users unique preferences. With multiple brace options, 2 different extension arms, and the ability to fold right or left, the user has 40 possible variations that can be configured by simply removing a few screws and changing up the configuration.

REAR ADAPTER: Manufactured as a Polymer/Aluminum hybrid, our rear adapter provides the OE fit of the polymer adapter with a heavy duty 1/4" thick aluminum insert to reinforce the mount for the stock or brace. Completely unique in design, this adapter provides improved stability by covering more surface area of the receiver.
APEX PICATINNY STEEL: these mount to any rear 1913 (Picatinny) rail. Manufactured from 17-4 stainless steel with QPQ Melonite coating. Rapid deployment feature and quick-lift folding
EXTENSION ARMS: Our extension arms are available in both straight or offset configurations. Straight extensions simply extend rearward, positioning the brace end in line with the hinge point. Offset extensions offset one end 1.25" from center. Each end is symmetrical, allowing the user to mount it in 4 different positions as shown to the right. These offsets can be used to clear objects such as an ejection port or charging handle, raise/lower a cheek weld for different height optics, or position the brace end higher or lower to suit your shooting preference.
All extension arms incorporate M-LOK slots along the full length of the arm. This allows the user to mount our VIS steel QD (Quick-disconnect) sling mount anywhere on the extension.
BRACE OPTIONS:With our modular design, the user has their choice of A3 Tactical Steady-brace (in Polymer or Aluminum), or the Gearhead Works Tailhook (MOD1 or MOD1C). Order Tailhooks HERE.
CHEEK RESTS:  The Xeno Modular Cheek Rest has three heights - 5/8", 7/8", or 1-1/8". The XENO mounts via M-LOK and also has an offset that allows the cheek rest to be positioned 1" offset of the mount, if necessary. The XENO is machined from aluminum with injection-molded Polymer spacers and cheek rest.
