War Lock Upgrade Kit – FS
Frontier Tactical introduces the War Lock Upgrade Kit – FS. Innovation and versatility combine to give your AR-15 rifle new capabilities. The War Lock™ transforms your AR platform into the Multiple Caliber System.
Unlock your AR.
The standard AR platform can already fire over 90 calibers, but requires either a dedicated upper receiver for each barrel, or the labor intensive removal and installation of a barrel. The War Lock™ forges your AR into a Multiple Caliber System. It replaces the traditional barrel nut and enables the quick installation and removal of War Lock™ equipped barrel assemblies. By installing the War Lock™ onto your AR, you gain the unmatched capability for caliber modularity. Imagine….one rifle for most calibers.
The War Lock™ is manufactured from the highest quality materials to provide the longest service life possible. We personally believe that by manufacturing high quality products any need for guarantees or warranties become largely unnecessary. It is our intent to prove that we appreciate your investment in our product. To that end, we diligently strive to provide you with solid value for your trust in us at Frontier Tactical™.
The War Lock Upgrade Kit – FS includes one Receiver Adapter Assembly; made up of one Lock Collar Assembly, one Lock Ring, and one Receiver Adapter. It also includes one Barrel Adapter Assembly – FS; made up of one Barrel Adapter Assembly – FS, one Transportation/Storage Cap, and one Installation Fixture. Additional Barrel Adapter Assembly – FS’s are available for separate purchase.
Our “Small Free Float Adapter” is designed to accommodate clamp on free float rails. The knurled section of the free float tube/rail must be able to fit our 1.360″ knurled outside diameter. All of our small free float rails and adapters are interchangeable.
**Compatible with many off the shelf free float rail systems. Picture of Midwest Industries rail is for illustration purposes. Midwest Industries rail is not included in this kit.**
With the War Lock™, you won’t need to make multiple trips to your vehicle for all the gun cases you take to the range. Simply pack up the rifle, barrel assemblies, bolts, magazines, ammo, and appropriate safety equipment into one case (or one case and additional range bag). Shoot multiple calibers all in one day without the hassle of multiple rifles.
The War Lock™ has been engineered to accept most commonly available barrels, rail systems and hand-guard assemblies. It is possible that the War Lock™ may require special fitting initially, or not be compatible with your components. As there are a multitude of manufacturers and tolerances for different AR builds, we cannot test every one. Please feel free to check our FAQ’s.
As with most AR accessory installations, Frontier Tactical recommends that the initial assembly of our kit be installed by a competent gunsmith or armorer. We recommend that headspace checks be done prior to firing for the first time. It is the responsibility of the user to ensure that appropriate safety checks have been done to their weapon PRIOR to firing with our kit. The user is responsible for compliance with all legal requirements for their area. Installation of our kit may void any manufacturer warranties. User assumes all risks and liability where applicable by law.
