What is the length-of-pull (LOP) on the SpecOps?
The SpecOps is adjustable from a minimum of 11.25 inches to a maximum of 15.25 inches by pressing a lever and pulling or pushing the stock to the desired length. If the rubber butt pad is removed, the minimum is 11.25 inches with a maximum of 15.25 inches. The rubber pad can be removed with a Phillips screwdriver and the removal of two screws. The butt plate of the stock is highly textured to improve shooter control.
Can I use an oversized safety or extended safety with the SpecOps?
Unlike the SpecOps Stock, oversized safeties can be used with SpecOps. Recommended oversized safeties can be found in the accessory section of the Knoxx website.
Why is the SpecOps suited for law enforcement and military applications?
The issue of length of pull (LOP) and recoil has long plagued military and law enforcement personnel. The military’s solution is the M4-style stock on the current issue M-16 and the SpecOps brings that solution to the pump shotgun platform. Now a 5’4” 120 pound soldier or officer can use the same shotgun as their 6’4” 220 pound partner. Proper fit of the shotgun to the shooter is crucial in ensuring firearm control and accuracy.
Is the SpecOps just for police and the military?
No, The SpecOps is perfect for:
Recreational Shooters – The ability to properly fit the stock to each shooter makes the SpecOps a smart choice for families and for target and competitive shooting.
Hunters – The same features that make the SpecOps ideal for law enforcement apply to hunters of all types. With a properly fit shotgun hunters will enjoy better control of their shotgun and will find pre-season practice much more enjoyable, making them better shooters and resulting in more game for the freezer. Turkey hunters will love the shape and angle of the pistol grip that will make the hours of turkey calling and waiting much more comfortable.
Home Defense – Experts in home defense all agree that the most important aspect of keeping a shotgun for home defense is user familiarity (that means practice.) With the SpecOps, the shotgun is one size fits all. A SpecOps equipped shotgun can be stored in the collapsed position for easy placement and extended to the correct length, even in the dark.
According to the factory:
Doesn’t this make my shotgun an assault weapon?
No. Pump shotguns are not regulated as “assault weapons”, they are only regulated by federal and state regulations with regards to minimum barrel length, and overall length. The SpecOps even at its shortest length, still complies with federal and state laws.
Is there a way to attach a sling?
Yes. The SpecOps stock comes with a sling swivel stud installed at the toe of the butt. In addition, there are two alternate mounting locations along with a slot through the stock to install a web sling. All sling mounting methods gives the shooter full utility with the stock mounted.
Is it strong and durable?
The SpecOps is made from high strength fiberglass-reinforced polymers for service in the most extreme environments. While ideal for civilian use, it has been designed and built for military and law enforcement professionals in the most demanding situations.
Is it legal? Yes. It is legal to install the SpecOps on any pump shotgun in all 50 states.
Can I replace the butt stock portion of the stock?
The SpecOps butt stock is not compatible with other M4-style stocks. The increased recoil energy generated by a shotgun requires the use of a heavier, sturdier tube than is found in standard M4-style stocks.
Is it difficult to install and use?
Once your factory stock is removed, the SpecOps installs by tightening one pre-installed bolt. Using the stock is intuitive and takes only seconds to figure out. Just squeeze the lever and set it to the LOP that works for you. There are five different settings available.
