Is there anything that tops the prs these days? I’ve mostly been looking at the prs but I know seekins and xlr hace precision ar stocks. I have a luth ar mba 1 I’m finally gonna upgrade, I just don’t like the kinda flimsy cheekpiece and less than secure thumb screws. It’ll be going on my 24” varmint ar that I use for paper steel and prairie dogs out to 650 or so. I’m 6’4 so long length of pull is only a good thing.
 
Primary arms has a real good deal on the seekins stock right now- $120. At 1/2 the price and 1/2 the weight of the magpul, it is very tempting. That said, it doesn't look 1/2 as easy to adjust. With the seekins name, I have to assume it's well built.

I've been eyeing the xlr stocks for a while, but haven't brought myself to pull the trigger. For some reason I can't wrap my head around them clamping to a round receiver extension. My bias says it will slip or rotate precisely when I don't want it to. But, this may be my next stock. It looks to be much more adjustable than the magpul, but not as convenient to adjust. I think they're lighter too. Not inexpensive.

I've got magpul PRS stocks on three rifles, so I guess I've made my choice. But, I've got a receiver set lacking a stock too and the PRS stocks are heavy and expensive, and while easily adjustable are not widely adjustable.

When you say "tops the PRS" I think you need to specify in what categories. I'd say the magpul PRS sets the bar for a "composite goodness factor" that would average all of the above, though that doesn't mean there are not "better." And, "better" for me may not be better for you. When I scratch together the cash, I think I'm going to try out an XLR...

It won’t slip.

Thanks for the reply. I should have been more specific with what I want and what I want to avoid. I want the length of pull to lock up solid and I want a thinner and stable cheekpiece, the luth ar cheekpiece is very wide/round and flimsy. I also like the adjustable buttpad height on the prs and xlr. Weight is a non issue, I pretty much just carry this thing from the case to the shooting mat or bench. The price is definitely attractive on the seekins, but I think it’s mostly between the prs and xlr. I’ll think it over for a bit, thanks all
 
The LMT DMR 308 has intrigued me as an alternative, but I can find ZERO information about it. It looks to be a little shorter than the PRS, but there are no specs to speak of.
 
I've yet to have a tube clamping type stock slip on me. I have a Tacmod on my precision AR, its similar to the XLR, and one of my favorite features that no one mentions and other stocks aren't capable of is buttpad cant. Once you get used to really fitting a stock to your geometry its hard to go back.
 
The seekins is really solid at 120 thats a steal. I run them on 2 bolt and 2 gas guns. Awesome stock! Im 6'2 and have a fairly long length of pull as well and dont use the spacers provided.

Does anyone know of the LOP on the Seekins is less that that of the Magpul? Also can the LOP on the PRS Gen 3 be reduced simply by putting leveraging Carbine length tube? If so, will that require a special spring specific to a .308 AR10 build?
 
The seekins needs a rifle length tube and the magpul can accommodate both with the provided spacer. You would need that clearance for the charging handle on a 308 gas gun anyway. Any standard large frame rifle length buffer and spring assembly will work. I use the dpms kit - tube, spring & buffer on my gas guns.
 
I have the Gen3 PRS with rifle length tube on my AR10. Too heavy and minimum LOP is too long. Minimum LOP on my Gen 2 PRS is one inch shorter than the Gen 3 (10" vs 11"). Does anyone know what the minimum LOP is for the Seekins?
 
I have several of the PRS stocks and an XLR chassis.
If you plan on frequently adjusting the LOP and cheek riser the PRS is nice for that but I personally set it and forget it.
The XLR is infinitely more adjustable in my opinion and has the benefit of adding weight if you prefer as well as a bag rider.
And regarding the clamp slipping, it's not going to happen unless you want it to.
When I was initially setting mine up I just lightly tighten some of the screws on the clamp and left some loose while fine tuning it and there was zero slippage under recoil.
 
Thanks N.Parish! Yes I was measuring just the stock. I was just messing around with the Gen 3 recoil pad. Easy enough just to make thin rubber replacement and keep the original for prone adjustability. Back to the XLR. A roughly 10oz weight savings is significant and with it on sale might be worth it. Still pondering over this one.

I hope this helps.

Sorry for the crudity, I didn't feel like pulling up AutoCAD or Creo to do it in. Please note that all dimensions are in inches and +- .010.

Edited: I should have clarified that this is a 308 DMR Buttstock. I do not know the differences in the 5.56 DMR Buttstock.

LMT DMR stock is the best precision gas gun stock there is IMO.
I've been considering an aftermarket stock for 2 years. Looked at Magpul PRS, Luth, LMT, and Seekins . Decided on the Seekins and took advantage of the Primary Arms sale. The Seekins was easy to install and everything fit perfectly. The cheek piece is easy to adjust. I set the LOP using 1 "Shim" and it seems about right on initial view through my scope.

I have a Seekins. It’s easy to set it up. One interesting thing is tha pulling the charging handle all the way to the back hits the front of the cheek price. Not a big deal but something I noticed. I like it because it’s light. PRS is good not sure the extra weight is needed for me.
 
I was excited about the FAB Defense RAPS when I first saw it, until I read the specs that the shortest LOP on an AR10 was 14.8", a full 0.5" longer than the PRS Gen 3.
