Questions & Answers
Will this fit my CZ scorpion + 3? Expert Answer

To mount the A3 Tactical Skelestock Skeleton Stock to your CZ Scorpion, you will need to use a picatinny (1913) rear interface adapter or a 2-bolt hinge adapter. Both styles of adapters can be found linked below, Sku# RSA030 (2-Bolt) and Sku# RSA031 (1913). Depending on what adapter you decide to use, you will need to select the stock that corresponds with the mounting method (either 1913 or 2-Bolt).

Does not fit by Curt, Verified Owner, January 27, 2024
Advertised that it fits most picatinny rails but it doesn't fit mine. It slides over the rail but there's no way to tighten it to the rail. Will be returning it.
