Sub2000 has a fairly stiff recoil spring. It’s location and the short charging handle make racking the bolt a bit awkward for me. Enter the solution.
The replacement handle from Twisted industries (scroll down to see it) allows a much better grip on the bolt handle. It still locks into the bolt lock notch, and reduces the pressure on the fingers to make loading and unloading a Sub2000 much easier. I highly recommend this item! Erin does too.
