Spuhr a-0029 works great with the vortex impact 4000 - Spuhr Wilcox Raptar Adapter

I mounted the Spuhr A-0029: RAPTAR Adapter to my Spuhr Ideal Scope Mount System Scope Mount utilizing the two srews that were provided with the product and properly torqued the screws to recommended setting. Then mounted The Vortex Impact 4000 to the Mount and torqued the 1/2 inch mounting screws to 45 inch lbs. This setup still allows plenty of room to rotate the Elevation Turret on my Nightforce NXS 8-32x56 .25 MOA Zero Stop MOAR C437 Rifle Scope. It's hard to beat a Spuhr Product. I love their ingenuity.
