RECEIVING OF NEW WORK DELAYED UNTIL FEB. 15, 2015

It's possible to have as much of a good thing as you can manage! With the interest in the new Aluminum Trigger Housing and Flat-Top and Collapsible Buttstock Mods, and in order to complete certain research and development work, we are not able to accept new work until mid-February. We're sorry to inconvenience our customers, but in the interest of maintaining the quality and range of our products, we need a little time to catch up. Inquiries about our products and services are welcomed; please see our Contact Us page. Many thanks for your patience, and to our customers who have been keeping us so busy!

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.

OUR AIM

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.

SAFETY AND RELIABILITY ANNOUNCEMENT
