Re: AR stock.
I finished this 6.5 Grendel build (pics below) not to long ago and the PRS works nice but it depends what your going to use it for.
Im starting another Grendel build (6.5 GDMR Clone build). They want $3,600.00 for one at Alexander Arms w/ no scope, mount or bi-pod. I figured I could build one thats less than half the price with the same parts. All I need is the barrel, Larue rail and gas block and its finished.
The bottom pic is the AA GDMR, When mine is finished it will look exactly like that one.
Sorry about tthe pics they were taken with my phone. Need to take some better ones soon. I upgraded the Harris bi-pod to a Atlas, Added a Accushot Uni-mount for the PRS, changed the Gill brake to a Smith ent. Vortex, added a FDE Magpul AFG Grip and swapped the Rock River trigger for a Geisselle SSA trigger. Like I said, I need to get some updated and better pics.
You asked if there is any other good stocks. Yes, there are many. Everybody has their own opinion on what they like. I like the PRS for bench and prone but I like the LMT Crane stock and Magpul CTR on my lighter AR's.
The 6.5 Grendel is a very good caliber and very accurate for a AR-platform. I love mine.
