Another fan of the KRG Bolt Lift here. The only time I like knobs is when I am using a chassis with a pistol grip. With standard stocks and prone/tactical stocks, they always seem to get in the way of my trigger finger because of the added length to the bolt handle. The KRG Bolt Lift can be removed when I make a stock switch... and knobs are a serious and literal pain in the back when slung the traditional way, muzzle up. Plus (and I am sure I am in the minority here) should you decide to sell your rifle later, you’ll have a wider audience… there have been quite a few rifles for sale here that I passed on just due to the knob.
