10 rouns single stack mag will not fit 300 wm rpr - Accuracy International MAGAZINE 10 SHOT

The 300 wm 10 round magazine is shorter mag-well wise compared to the two 5 round mags that come with the 300 wm Ruger Precision Rifle. You can wiggle it off because it is loose, and you can also push the magazine all the way up to the upper wall of the rifle receiver because the mag stopper in the magwell is too far forward to stop the magazine. Other than that, it’s a solid magazine. I just welded a piece of metal spacer to the magazine to make it fit perfectly into the RPR magwell. I dont think these 10 round 300 wm magazines were made for the RPRs.
