Limbsaver recently released a pre-fit recoil pad for Magpul stocks. Using the same NAVCOM material found in other recoil pads in Limbsaver’s lineup, they fit both the Magpul MOE and CTR rifle stocks. Limbsaver claims their recoil pad reduces felt recoil by up to 70% and helps maintain target acquisition. MSRP is $42. They’re also available on Amazon for $40 with free shipping.
While it doesn’t reduce felt recoil nearly as much as the Limbsaver, Magpul’s own recoil pad goes for $17 and does help reduce recoil a tad.
