Wyatt's Extended Magazine Box Complete Kit - PRC Specific

Work great. I've used several on customer rifles, give opertunity seat bullets out over factory box

2nd one of these that I purchased. First was for the 6.5PRC; most recently for the 300PRC. Works flawlessly. Just make certain that your receiver is milled to accommodate the longer box and that the bolt stop is far enough back to allow enough bolt travel to pick a round up out of the longer magazine.

After struggling to get the OAL needed for my 300PRC from a detachable magazine I went this route. I also prefer a flush fit bottom metal and this paired nicely with the oberndorf bottom metal. It was a fantastic fit in my M5 inlet grayboe terrain stock and required no gunsmith modification for the stock or my Bergara Premier rifle in 300PRC. There are 2 small modifications I plan to make after installing this. The cut on top of the aluminum follower is quite sharp and scratches brass. I will knock the edge off of with some light grit sandpaper. Also my long berger 245gr rounds take a little force to chamber overcoming the feed ramp. I will be polishing the feed ramp. Very happy and gives the OAL advertised!

1st - very fast shipping by RHR. 2nd - works flawlessly in the Defiance Deviant Hunter SA Mag that I built a 6.5PRC on. Minor note - stocks inletted for standard SA BDL magazine will need a little bit of re-inletting. Not much - aasy to do with a hand file.
