Good solid mounting - C&H Precision Weapons Walther Defense PDP 2.0 Adapter Plate

Installed without a hitch. The instructions were very clear. Using the T-nut design increases available threads for a more secure attachment of the red dot. Low "deck height" gave me good co-witness with the existing iron sights, which was a pleasant surprise as I had expected to replace both front and rear sights on my PDP. With this plate and the Osight SE I don't have to change iron sights to get a co-witness.
