SierraPapa now has our 07 FFL
SierraPapa is now legally able to receive your CX4s and perform a variety of gunsmithing work, including our new Flat Top and Collapsible Buttstock mods. As always, we do NOT need your gun or even your lower to install our Hammer/Trigger/Spring Kit-- just send in your housing as per these instructions.
At SierraPapa we provide the aftermarket parts that make the Beretta Storm CX4 into the carbine it deserves to be. Since our aim is to "improve the breed" we only supply CX4 Storm parts and accessories of superior design and the highest manufacturing quality. We welcome suggestions from users for the improvement of our present products and any recommendations for new Beretta CX4 accessories that you may wish us to introduce.
