This bolt-on thumb rest provides a comfortable and repeatable thumb position on the strong side of the grip without permanent modifications to the chassis or plastic stock skins.  The thumb rests are manufactured from composite Nylon II material, resulting in a strong, thin, and perfectly textured interface.

Please note that the “locking” stock capture on the folding AX rifles is deleted in order to install the thumb rest.  The butt stock will still fold 100% closed, but it will no longer be captured in the plastic retaining piece.

Available in the following configurations:

  •  Low – similar in angle and placement to the Masterpiece Arms (MPA) EVG.

Compatible Rifles (Rifle Families):

NOTE: PLEASE SPECIFY THE CORRECT RIFLE FAMILY AND CONFIGURATION WHEN ORDERING.  AE, AW, legacy AICS, and most fixed stock variants are NOT compatible with the thumb rest.

Version “AT,” which requires a special metal threaded insert.

  • Factory AIAT – folding stock only 
  • ATAICS – all folding stock variants, fixed stock variants in 300WM and 338LM ONLY
  • Pre-14’ factory AIAX – folding stock only
  • Pre-14’ AXAICS – folding stock only

Version “AX”

  • Post-14’ factory AX, AXMC – folding stock only
  • Post-14’ AXAICS – folding stock only

    This thumb rest provides an excellent and more importantly a repeatable location for your thumb. Highly recommended!

    Great product, super easy install. Makes for very rapid and repeated indexing for proper hand position every time. Only minor suggestion I have is to possibly find a way to reuse the folding stock detent on the rear attachment point of the thumb rest. I’m sure for average shooters it’s not an issue but when deploying all the time having the stock secured is necessary for storage and fielding in low profile environments. My suggestion only applies for people that run a gun for a living other than that it’s a great add on. Great product, fast shipping, great company.

    Wasn't sure if I'd like this and I wasn't sure about up 3-D printed part but after receiving it and trying it out I liked it enough to buy 2 more.

  • Great Addition
