SierraPapa now offers the flat top conversion we performed on our own CX4 (pictured on the Home page and to the right), in response to the demand from so many customers.

This modification includes removal of the "ears" and milling of the upper surface completely flat and smooth. During this process, the cavities that lie under the ears are exposed, and filled at the front cavity with a milled aluminum block, to provide a sturdy anchor for one of the two added rail screws, and at the back with a milled black nylon block, to blend with the rifle body. The front aluminum block is covered by the extended flat top rail, and the rear black nylon block remains visible. The stock white nylon block under the front ear, present in your rifle as you received it from Beretta, will be exposed and remain partly visible after this modification is performed. Part of it will be obscured by the rail-- please see the pictures on this page.

Included in the cost of conversion is the black-anodized aluminum, 14" picatinny rail we designed and custom-machine specifically for the CX4. Its groove accommodates the seams of the CX4, and the longer length (14" as opposed to the stock 10 7/8") permits the shooter to affix a diverse range of accessories.

Price for complete Flat Top Modification and 14" Top Rail: $390.00*

We do NOT need your lower to perform this mod.
