The Signature Series features one-of-a-kind rifles designed, built, and backed by the most trusted names in firearms.  We handpick partners – many of whom you have come to know and trust – who share our passion and values to design their signature firearm.  From barrel to buttstock, to optics, lights, slings, triggers, Cerakote and more – they dream it, we build it.  For you. 

The WPSM4A1 was designed by John Lovell of Warrior Poet Society to be your go-to, do-it-all rifle - chambered in 5.56mm NATO.

This completely custom build features our cutting-edge and heavy-duty RIS III rail. Known for its SOCOM legacy and rock-solid 6-bolt System, the RIS III makes the WPSM4A1 the perfect do-it-all rifle.

Paired with the Holosun 515 GM atop the Unity FAST Micro Mount and a pinned and welded Surefire Warcomp. Owners can quickly acquire and keep shots on target time after time.

The Radian Raptor charging handle, Radian Talon safety and Railscales components make for comfortable and familiar ergonomics, while the first-time-ever OD Green Cerakote sets the WPSM4A1 apart from any DD currently in the market.  And finally, the Geissele SSA trigger makes every shot crisp and consistent. 

Shipping with the WPS Rifle sling, a signed copy of the Warrior Poet Way, a custom challenge coin, and a matching hard case, this kit includes everything you need to hit the range.

These rifles are built-to-order and selling fast so, order now because delivery times may vary based on demand.

  1. Highly recommended, if in your price range.
    I put 200-250 rounds through the WPSM4 and the weapon performed flawlessly, the Holosun is a great optic and the unity mount is a major game changer. The surefire warcomp does make a difference to the recoil mitigation compared to the standard A2, the radian charging handle and safety selector make the weapon feel smooth even more high quality. The Giessele trigger says as promised every shot being crisp, railscales components are great especially the little hand stop. The WPS sling is by far the best sling i’ve had out of 3 i’ve been previously running, easy to adjust length and tightness. The appearance of the M4 is very appealing and overall just great looking, was a little skeptical about the OD green cerakote but was very pleased when i saw it in person great color.
    The WPS M4 overall is a great Weapon and comes with very premium attachments that would take otherwise time to order and ship and put them on yourself. Overall very satisfied with the WPS M4 and was worth the price in my opinion. Although 1 issues, i have to tighten the pistol grip because it has become a bit loose.

  3. WPS M4A1
    Awesome rifle, first time at range 200 plus rounds through it, not one misfire or issue. The picture doesn’t do the green Cerakote justice, the OD green and awesome. Holosun 515 is crystal clear. 10/10 …. It’s a DD need I say more
