SierraPapa is now offering a conversion that many of you have asked about after seeing our own modded CX4 on our home page. The Collapsible Buttstock Conversion removes your factory buttstock, adds a right/left sling mount, and prepares it for replacement with the AR-style buttstock of your choice. (Please note you must supply your own buffer tube and buttstock to us. We cannot ship firearms that do not have the new tube and stock installed.) Customers can choose from 6 different overall rifle lengths with the adjustable stock for an optimized shooting experience.
The process of conversion is as follows: Upon receiving your rifle's lower assembly, the factory stock is removed and the lower is placed in the jig of our CNC mill. The center of the lower is determined, and a cavity is milled out and then filled with a threaded aluminum plug. After a 24hr curing period, the lower is placed back on the mill for sizing and threading. Finally, the buffer tube and adapter plate (featuring two sling mounts) are installed, and the work is inspected.
Please make sure you include your buttstock, buffer tube, and accompanying lock nut in the box when you send us your rifle, or that you have it shipped to us directly from the supplier. We cannot proceed with your conversion until we receive the new stock, tube, and nut. Please call us at (503) 621-3017 if you have questions about suitable stocks and tubes.
