    I own two of these now, I got one for my T3x and T1x. I like the simplistic design of it and it is a small profile. It makes running the bolt fast really easy and offers excellent grip. It’s awesome!

    Love it. I ordered the black version with a black handle for my Tikka. It looks and feels great. Bolt manipulation feels so much smoother. Highly recommend this upgrade.
