The Mordax Venom is the most recent addition to the growing Western Airguns stable as a select-fire pistol. The enhanced evolution of the Mordax air pistol, it is available in .22, .25 and .30 calibers and combines precision craftsmanship with cutting-edge upgrades. This American-made lead launcher should appeal to PCP aficionados that enjoy hunting, target shooting, casual plinking as well as those tactical enthusiasts. Thanks to Airguns of Arizona for the loan of this .30 caliber Venom to review.
The Venom version grew from the short-barreled model having an underbarrel reservoir tube. Accomplished by adding the Venom Booster Plenum, a drop-block plenum that provides the extra room for a 300cc carbon fiber air tank. Rated for 300 BAR working pressure, the User Guide indicates both HPA and nitrogen can be used in these airguns. This configuration not only boosts the available air, but optimizes air delivery to increase energy output up to 76 foot-pounds of energy in the .30 caliber. The tank pressure gauge is affixed to the left side of the booster and the fill port opposite it on the right side. The regulator pressure gauge is located on the left side above the trigger and a short picatinny rail is on the bottom of the Booster. Speaking of picatinny rails, a full-length one runs along the top incorporating a non-adjustable post sight on the front and an adjustable notch-type rear sight. The Venom arrived with a Hawke Vantage 1×20 red dot already mounted. A 4.2 ounce, 2.9-inch-long optic that was an excellent choice for this pistol with the 8.5-inch American-made barrel.
It sports a 10.5-inch long aluminum side-folding stock with a QD sling point that turns it into a carbine. The OAL of the Venom with its stock folded, is only 16 inches with the 300cc carbon fiber bottle configuration and without the compact (4.5 inches) 0dB silencer it ships with. Adding the silencer back brought the OAL to 17.75 inches. Unfolding the stock brought the OAL to 27.75 inches and the Venom with the Hawke red dot and compact 0dB silencer weighed in at 4.96 pounds. The Venom is imminently portable and, AofA makes this point by delivering it in a very nice, light gray Savior backpack carrying case.
The Venom is fed by a rotary, two-piece steel magazine holding 12 rounds in .30 caliber. To load, the thin metal back plate is separated from the magazine body and pellets are dropped nose first into each opening. The back plate is replaced and held by magnets. The loaded magazine is inserted from the right side after retracting the magazine release lever, inserting the magazine into the breech, and rotating it counterclockwise slightly until the magazine release lever locks into place. A side benefit for those who already own a Western Airguns Sidewinder, your magazines will work in the Mordax as well.
The Mordax trigger is a two-stage, non-adjustable unit and the trigger pull measured an average of three pounds, 1.7 ounces across five pulls. The pull feels heavier, yet it is a new gun, and should smooth out after additional break in. To those unfamiliar with Western Airguns and their valveless construction, there is no charging handle or cocking bolt. So, extra caution is required once a loaded magazine is inserted into the gun. When the safety is off a trigger pull will discharge a round with no other action required. Conversely, there is no way to de-cock these airguns so the proper procedure to make certain it is unloaded is to remove the magazine, point the airgun in a safe direction, and dry-fire several times. Additionally, you must fully release the trigger on these SA/FA airguns in Semi-auto mode after each shot or potentially cause a misfire.
Directly behind the trigger is the Power Adjuster screw. Holding the airgun upside-down, turning it counterclockwise with a 3.5mm hex wrench increases the power and vice-versa. The User Guide recommends only adjusting the Power Adjuster knob if you have a chronograph as the gun was tuned at the factory for optimal performance. The grip is a mil-spec unit that has a nice, grippy feel, and can be swapped for your choice of grip.
Now to the “giggle switch” on the Venom. The selector is a three-position switch on the left side of the airgun. SAFE position blocks the trigger; SEMI is for discharging single rounds and rotating all the way over to FULL empties that twelve round magazine pretty quickly and is a bunch of fun! Full auto mode requires a minimum regulator pressure setting of 135 BAR and in full auto, you may get up to three full magazines before needing a top off.
This .30 barked loudly as you can imagine. Ear protection would be prudent when no sound suppression is involved. The compact 0dB did a decent job mitigating the bark, still, I wanted to play with a couple of other .30 silencers. A full-length 0dB was tried first. It added length and weight to the Venom without that much of a change in my humble opinion. Next I tried a Yokozuna by DonnyFL, which did seem to quiet the Venom a bit more at the expense of additional length and weight. As expected, the POI shifted slightly with the different silencers.
The User Guide included with the Venom actually describes the original Mordax configuration. A lot of the information within it covers both platforms with exceptions such as the ability to swap the fill nipple from one side to the other by simply pulling it out and reinserting on the opposite side and adjustment of the regulator pressure. WAG strongly suggests the user not adjust the regulator as it has been factory set for optimal performance. The warranty can be voided if done incorrectly. For the tinkerers out there who just have to squeeze out the most FPS from their gun/pellet/slug combination, the regulator adjustment screw is in the center of the bottom picatinny rail. The gun must be depressurized in order to reduce regulator pressure.
Results at 25-yards were excellent with one ragged hole groups using JSB Exact .30s at 44.75 grains. My supply of .30 pellets was limited with the JSB Hades in the same weight. Of course, they performed equally well. Regulator pressure was at 150 BAR and the chronograph showed an average of 695fps with a spread of 30fps and SD of 10.2fps. Average FPE was around 48.5 without moving the Power Adjuster from how it was shipped. In that configuration I got three full mags before needing to top off. I had no .30 caliber slugs in inventory and wondered how this short barrel would handle them. That is something a new owner will have to experiment with. Should this short barrel not be up to the task, an optional 14-inch barreled version called the Long Strike Venom is available. Happily, the Long Strike still fits nicely into the Savior backpack that come with the gun.
Made in Sheridan, WY with almost entirely U.S. supplied parts, the MSRP lists at $2396 in either the short or long barrel configuration. The Hawke optic is not included, but can be added for an MSRP of $120. Some excellent accessories are currently available for the Mordax as well, such as a stock adapter to increase the LOP about two inches; but only for models sold after February, 2025. Also available is an adjustable cheekpiece. Additionally, for the .22 and .25 models, extra barrels may be purchased and easily swapped out.
