    Bought these for my Ruger RPR in .338 Lapua and these extensions slide on and fit excellent. They fit the accurate mag 99% spot on. Only gripe is that when you depress the mag spring all the way into the extension, the follower fits snugly and will get caught. It only gives my rifle 5+1 but aesthetically improves the rifles presence if that matters. I’m sure their long action extensions for smaller calibers will give +2-3. Build quality is excellent and the piece itself feels robust. Overall wish it would give me +2 rounds but nonetheless I am completely satisfied.
