Stew’s Ready Review- the warlock

The transition from military to civilian life varies in difficulty. For myself it was made relatively easy by the fortunate circumstance of events that slowly separated me from the brotherhood. Shortly after returning from Afghanistan, I was transferred to another platoon and over the period of 14-months, I saw each and every member of my original sniper section and scout platoon disperse to either a new unit or out of the Army and back into the civilian life.

My first sniper section leader, SSG Robert Stewart, is the only reason I was selected to be in the sniper section to begin with. He inspired me to burry my humility and proudly accept the position of ‘rear-security’ despite my lack of official sniper training. Shortly after which, he was transferred to a line company position where he would carry out the deployment as Bravo Co., 3rd PLT, 3rd Squad Leader.

Upon returning from Afghanistan, he would spend two years in a low profile position helping wounded warriors in their transition out of the military, while attending his own much needed medical screenings for service related injures that had long been neglected. You can now find him working quieting on his own personal ranch, where he continues to offer his finely honed skill set by testing the capabilities of new weapon systems.


Below you will find the official written review of Robert Stewart’s experience with the Frontier Tactical Multiple Caliber Weapon system, the WarLock.
***The following content is copy written by Robert Stewart, however he has allowed me to publish this review on his behalf.


Tactical Frontier’s War Lock multi caliber system. Weighing in at only 11.04 Oz. it’s going to be the next big thing in the AR community.

I won’t go into great detail on assembly and operational properties of the system. The guys from Frontier Tactical have great videos posted on YouTube. I’d rather detail the versatility, durability and benefits of the system.
Initial inspection


Light weight and well balanced. The War Lock seemed durable and well engineered.
This was proven on a three day stent In the woods. I wanted to see how well the system held up to the elements. Three days of rain, dirt and dust. The War Lock system  held up to the test. I thought for sure without wiping the internals down I would eventually find surface rust on the locking mechanism. The coating held up to multiple barrel changes. Showed no sign of wear on any connecting parts ( locking ring, locking collar, receiver adaptor or barrel adapter). With this being said I have no doubt that with the proper care and maintenance as outlined in the owners manual the War Lock will last the life span of the rifle.

Carrying the weapon system with a single point sling and military style kit. Proved the War Lock was able to hold up to being knocked around and rubbed against the kit without compromising the weapon. One issue that arose. The locking pin hitting the molle and occasionally snagging or spinning the locking pin out of position. It was easy to negate this by spinning the lock collar where the locking pin is facing out or under the optic at the 12 O’ clock.

      The multi caliber’s reviewed were the 300 Blackout, .556 and 264 LBC. After literally two minutes of handling the War Lock I was able to confidently switch between barrels as would any shooter who is familiar AR platform.
     My load out for this review:
3×30 round mag .556
3×20 round mag 300 BLK Out
2×10 round mag 264 LBC.
I was able to carry extra barrels with a shot gun scabbard on either side of my assault pack (barrels facing down). This allowed me to quickly ID the barrels for a faster transition.

Extra bolt was carried in an auxiliary pouch with a protective make shift container from a barrel tube I had purchased earlier.

With that in mind I knew it was crucial my load out had to be set in a manner that was easy to identify rounds/mags and barrels for both day and night.

Magazines were marked as followed:
.556 one half inch strip 100 mile hr tape bottom of magazine.
300 BLK Out 2 one half inch strip  100 mile hr tape around bottom of magazine.
264LBC no markings needed mags are different in shape and size.
This made it visible during the day and I could count the lines with my fingers at night.
Then there was the issue of marking the barrels. I realize that if indeed used in the military it’s would be tied down. So I tied one knot in the tie down line to the 300 blackout and two knots in the 264LBC. Now it was as simple as counting the knots along the tie down follow it into the scabbard and I knew exactly what barrel I was grabbing. This load out was easily carried and managed. Would’ve been practical for short missions lasting 24 hrs. I don’t see soldiers carrying more than one extra barrel. Extending  mission time a lot longer by 48 hrs. With the wide variety of calibers the military application are endless. From shorter barrels and heavy hitting rounds of 300 BLKout for room clearing. To the versatile .556 and the flat shooting 264 LBC. War Lock makes any AR 15 a combat multiplier.
Reliability and Function


I wanted to see if the structural integrity would hold with multiple round. Would this weaken the bond between barrel and receivers. So I started a round count on the barrels. I am using the same upper receiver for all barrels.
.556(55g)-350 rounds shot with one malfunction. After inspecting the round it was determined the primer was deep set. Causing a light primer strike. SI magazine used 
300 BLKout.- 160 rounds zero malfunctions. SI magazine. 
264LBC(123g) 100 rounds one miss feed. 
120g. 40 rounds zero malfunctions.
    “For anyone purchasing the War Lock. I recommend the AR Ready kit from Frontier Tactical. The Black Hole barrels outer coating is phenomenal. I would compare it to the durability of what is used to line truck beds. Absolutely no surface rust after three days of rain. The Black Hole barrels and magpul accessory complemented each other well.”
