Product Description
Triangle stocks aren't just for AK's, they add a unique look to just about any firearm you put them on. With our modular mounting interface, it allows the user to put a Triangle Stock on just about any firearm.
ALUMINUM: Our new Aluminum Triangle Stock is machined completely from 6061 aluminum and profiled for weight savings. It has rear texture machined into the butt-plate surface, or you can install the optional textured rubber butt-pad.
POLYMER: Our new Polymer Triangle Stock is injection-molded from super rigid 30% fiber-reinforced Zytel, by DuPont. This isn't your typical "plastic", this polymer easily rivals the aluminum, at a much more economical price and reduced weight.

Sure-Lok 1913 Folding Hinge - Patent Pending The Sure-Lok™ Folding Hinge features 17-4 stainless steel MIM construction with a QPQ finish for strength, wear resistance, and corrosion protection. A push-button release allows controlled folding, while the quick-deploy design lets the stock snap into the deployed position with a firm pull, no extra steps required. Its compact, low-profile design mounts securely to any 1913 Picatinny rail using two cross-bolts for maximum rigidity, or a single centered cross-bolt when space is limited, delivering fast operation, durability, and repeatable performance. |
