Just received a stripped lower and LPK for a precision build. Need to decide which stock I want for a 20" 6.5 Grendel. Definitely want fixed or a UBR that allows a good, solid cheek weld. I'm trying to decide between the aforementioned UBR, A1 length fixed, A2, or the now shipping PRS Gen 3.

What do you recommend and why?

If its a long range AR with a nice optic I would spend a little more and get the PRS. Not having a consistent cheek weld can be a pain.

I have a 18" grendel with an A2.
Why? Because I'm poor.
I was gonna get the luth-ar at a later date but now I don't think I will.

Magpul MOE Rifle Stock is my favorite.

I'm in the process of assembling what I hope, will be my first AR built for precision. I'm holding out for Magpul 's Gen II UBR. Why?
Can get a solid cheek weld, ability to use the A5 buffer, will be adjustable so I can teach the kids, accommodate different clothing depending on the weather and lastly.....I think the UBR looks good.
I've considered other routes but the A5 system is something I want to try.

Colt CS stock.  A2 goodness in A1 length.

My A2 clone and Mk12 both have CS stocks.

Which the UBR provides.

The adjustable cheek piece of the PRS is just for looks. NTCH is the correct way to shoot and I've never felt the need for a riser anyway.

A2 or A1 - depending on how big you are as a person.

Adjustable cheek pieces allow you to get your eye directly behind the scope. I wouldn't have a precision gun without one.

NTCH on a precision gun sounds like a great way to scope ring yourself.

Op I just built this 20 inch precision rifle for a friend. I am building a similar rifle for myself with a different rail and an A2 stock.

I ordered one some time ago and am still waiting. I think it was from Brownells. Hoping they start shipping soon. I'll post up some pics and thoughts after it shows up.

My .308 is a pig for a number of reasons but one was the PRS. 

I had to put it on a diet and switched the PRS for a SOPMOD, I still have the cheek weld to use my ST-10 and saved a goodly amount of weight.

SOPMOD 4 Lyfe

If it helps you OP, I'm soon adding a PRS Gen 3 to my LaRue PtOBR 7.62 and a UBR Gen 2 to my LaRue OBR 5.56
Ditching the CTR and RAT stocks.

Uhh, cantilevered mounts exist. KAC, SPUHR, etc. Never had a problem with "eye height" getting right behind the objective in a perfect sweet spot for the eyebox.

My SR-25s came with SOPMODs and I think they are terrible for use with a rear bag. I think the STR is a good replacement if you like the SOPMOD cheekweld but want to be able to use a bag in the prone.

Magpul keeps delaying the PRS Gen 3 so who knows when it will be out.

The PRS is an excellent stock. In addition to being adjustable, it helps to properly balance an AR with a heavy barrel.

Everybody's different, but for lots of people, including me, a standard AR stock is too low to obtain a proper cheek weld and keep your eye centered in the scope tube. I use both the length of pull and the riser adjustments on my PRS.

Now I will say I find it weird based on pictures posted here how many people buy a PRS only to keep the buttplate and riser dialed all they way in.

I'm not using a cantilevered mount on something like a 6-24. YMMV.

If you can get setup up on your scope using a nice solid cheek weld with your eyes closed and then open them up to be perfectly centered on your reticle, you must be a unicorn. It doesn't work that way for most people hence the existence of adjustable comb heights.

I know plenty of people using cantilever mounts with larger 5-25, 6-24 type stuff though I personally would never scope an AR with something like that. My current "precision" 20" rifle is wearing a Kahles k312i in a cantilever KAC mount. Eyebox is yuuuge and I have a huge head, its very easy for me to get behind.

Some of the bigger scopes had reticles I really would like to try with this rifle (SR-25 APR) but for my uses I value FOV, eyebox, and the like in a semiauto platform while maximum magnification rates very low.

Don't overlook Luth AR stocks.

Much cheaper than PRS and it does pretty much the same thing.

I would go with the PRS myself. Oh wait, I did. <img src=http://www.ar15.com/images/smilies/icon_smile_cool.gif border=0 align=middle>




Then again, I like the UBR as well.

Link Posted: 12/16/2016 6:29:26 PM EST

I actually like the Luth-AR stock better then the PRS and I have both. My 6.5 build has the Luth-AR stock on it.
