-NOTE: NOT COMPATIBLE WITH KELTEC P50 DUE TO CHARGING HANDLE INTERFERENCE. THE P50 REQUIRES THE OFFSET SIG HINGE AND CAN BE PURCHASED HERE.
- PICATINNY (1913) MOUNT - HD steel Leverage style hinge with our APEX interface
- 12 DIFFERENT EXTENSIONS FOR CONFIGURING DIFFERENT LENGTHS AND OFFSETS
- HINGES CAN FOLD RIGHT OR LEFT
- HINGES LATCH IN BOTH FOLDED AND OPEN POSITION
- 5 BUTTPAD OPTIONS
These Modular stocks are designed for firearms that already have a rear Picatinny rail. They are available in multiple configurations to customize your stock for just about any application. Ships with any one of our 12 different extension arms and any of our 5 different buttplates.
The A3 Tactical hinge can be mounted to fold left or right, and latches in both the open and closed positions.
The offset extension arms are available in straight or offset, and in 6 different lengths. The offset extensions allow the user to configure their stock in 4 different setups as shown in the appropriate product images. This allows the user to raise or lower their cheek rest, avoid obstacles like side charging handles or ejection ports, and raise or lower the buttplate.
All components are machined from aluminum and anodized low-gloss black. Made in the USA!
NOTE: Due to charging handle interference, SIG MPX/MCX applications work best with the steel leverage hinge. The aluminum push-button hinge can be used, however it can only be configured to fold right, with the push-button facing downward.
NOTE: Extension lengths are actual length of the extensions. To calculate overall length, use the following INFO:
| ITEM | LENGTH TO ADD |
| -Hinge | +7/16" |
| -Minimalist buttplate | + 1/2" |
| -A3 aluminum buttplate with rubber buttpad | + 11/16" |

APEX Leverage hinge: This is a HD steel hinge that uses a tensioned release to fold. Similar to most tensioned hinges, the user lifts the stock/brace to release the latch and fold. In the folded position the hinge has a tensioned detent that holds it folded. The user can simply pull the brace for deployment. |
|
|
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 a QD (Quick-disconnect) sling mount anywhere on the extension, or any other M-LOK accessory. |
 |
| CHEEK RESTS: We have 2 different cheek rests available for the PICATINNY folders - the clamp-on, non-adjustable cheek rest, or our XENO Modular cheek rest. The clamp-on is a fixed-height polymer rest measuring 4" long that raises the cheek rest 1/2". The Xeno Modular Rest can raise the cheek rest 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 has an aluminum mount with injection-molded Polymer spacers and cheek rest.
