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.

Purchased these to try on MDT mags running in a Seekins PH3 7PRC that I have been using for NRL hunter. They are compatible with the mag body and gave and additional 2 rounds. One thing of note, you do have to retune the spring significantly, and one of my mags had a spring that seemed to be somewhat weaker than the others and had to be retuned by the end of a match. Overall, the extensions themselves are very well designed and perform exactly as advertised, I plan on purchasing some SA extensions for my 6.5 Creed as soon as it arrives from LRI.
