7. Daniel Defense RIS III 12.5" M-LOK FDE – Near Mint  
Daniel Defense RIS III 12.5" M-LOK rail in FDE.

This example is in near-mint / like-new condition and has been inspected carefully. There are only two extremely minor cosmetic marks worth mentioning: one very faint mark approximately three-quarters of the way forward on the right-hand side, which is now nearly imperceptible, and one tiny mark at the base of the rail. Both are superficial and very difficult to notice unless specifically looking for them.

Otherwise, the finish is extremely clean, the rail is straight and sharp, and the overall presentation is excellent.

The RIS III is Daniel Defense’s updated free-float rail system, combining the proven bolt-up mounting system with M-LOK attachment slots and a continuous Picatinny top rail. This is the desirable 12.5" FDE configuration.

Near Mint / Scans Uploaded: Very clean example with only the two tiny cosmetic marks noted above. Please review all photographs carefully as they form part of the condition description.
