I recently picked up a 34mm 25 MOA P-ROM L-Model from Rifles Only.
First of all, I want to thank and applaud Marco and Kate at GDI and Lisa at Rifles Only for customer service that is second to none. Truly outstanding people behind this product.
Second, this mount is impressively beefy, yet not chunky. You get the sense that it has only the material necessary to get the job done, but it leaves you with no doubt that it will withstand whatever you can dish out. It came in at 10.5 ounces on my Zieis scale, as pictured:
Finally, I was not previously aware of the particular ring design employed on the P-ROM L-Model. The rings do not form a circle per se. As seen here:
Marco was kind enough to provide a detailed explanation of this design. He gave me permission to post it on Sniper's Hide as I felt that others might find it useful. His comments follow below the line.
To better orientate you to our mount's design features, I will define the details of the geometry:
Please let us know if we can assist you in any way going forward; thank you for your interest in our

To better orientate you to our mount's design features, I will define the details of the geometry:
- Our P-ROM L-Model Ring Caps are engineered to not "sit flush" with the inner aspect of the mount's Lower Yoke / base; this is by design. Most ring caps approximate 180⁰ of maintube coverage, with the (lower) ring yoke covering the remaining 180⁰. That said, you will typically see standard ring sets sit flush on the inner contact area (when the ring caps are assembled w/o the scope mounted).
- Our mount's Lower Yoke / base is designed to cradle the scope's maintube over a greater degree of area (past 180⁰); this is also by design. The additional degrees of Lower Yoke proves to better stabilize and support the scope under vibrational and in-line shock impulses during live-fire. As a result, the upper Ring Cap and Lower Yoke do not sit flush on the inner contact area w/o the scope mounted).
- The non-flush design feature allows for variances in dimensional tolerances of the scope's maintube. A spec deviation in the maintube's diameter of as little as .0005 per side, (.001 (one thousandth) total), will significantly effect the lockdown capabilities of the ring cap, thereby causing the scope's maintube to remain loose within the rings, and not torqued to spec., (while the ring cap screws themselves may be torqued to spec). Our design allows for any deviations that may occur from one scope manufacturer to the next.
NOTE: For reference, please note images below of three different industry examples that also utilize this design feature.
- The flat "gap" that you have referenced on the Lower Yoke is also engineered into the mount's design, as it allows for relief on the scope's maintube, in addition to positioning the Ring Cap in the proper location for torquing in the event of an undersized maintube. NOTE: For reference, please note images above of three different industry examples that also utilize this design feature.
