Adapt your bolt to a standard male thread with these stainless bolt handle adapters. They are lathe spun and threaded to a Class 3 fit, and allow you to use most aftermarket bolt knobs.

These have become necessary in the last few years as action makers go to smaller stock in their bolt-making process and use female attachment points on a shorter handle.

 

NOTE: If ordering for a BigHorn TL3 please confirm that your bolt handle has a female thread in the handle. Some older TL3s have a threaded male end on the handle, which will render these adapters  incompatible.

    Completely changes how the bighorn bolt feels. Makes it feel heavier/sturdier. The bolt handle helps your hand get a good purchase manipulating the bolt. Awesome parts.

  15. Rated 2 out of 5

    Bart (verified owner) – August 18, 2022

    Fits WAY too tight! I had to apply, what I would consider, an inordinate amount of torque to thread it in completely, and this was after running it in and out several times and using grease. NOT good!
