View Full Version : Magpul PRS or UBR?

02-22-2011, 10:39 PM
Ive narrowed it down to 2 stocks. I will be putting it on a 20" AR shooting a 5.56 and its going to be a bench gun primarily. Ive read that the UBR may balance the heavier front of the rifle because of its weight but using a bag in the rear is nearl impossible with it. It also has a longer adjustment which I like.

The PRS has a adjustable cheek weld like everyone knows, but to me it looks like its placed too far back and may cause eye relief problems. I do like the PRS has the option for a monopod as well.

I've had the CTR stock previously with an Eotech and I had no problems with the standard cheek weld. But never used a scope on an AR....

So any input? Which one would you prefer and why? Im not asking for you to choose for me, im just looking for pros and cons of each.

A2 stock is really nice as well.

For a bench/ precision gun I would go with the PRS. It has the adjustments for the cheek and shoulder plus you can also get the monopod for the bottom rail. I have a couple of them on my .223 and .308 rifles and can't complain about them at all.

I would definitely go for the PRS. I have one on my rifle and LOVE it. I had a Magpul CTR and have an A2 on my M16A4 with an RCO (ACOG) so I have lots of rounds with different stocks and the PRS is freaking awesome. I wouldn't even have the UBR as a possibility for a bench gun, go with the PRS or a standard A2, the PRS is a work of art and works great and you can never go wrong with an A2.

I'm leaning to the PRS as well. I'm just wondering about the distance of the cheek riser. Or if I'll even need it

I have both. I keep the UBR on my 20" AR-15 and PRS on my 20" AR-10. The PRS cheek riser is positioned far back to allow clearance for the charging handle. I don't find it to be a problem while benched but it is different from my usual cheek weld closer to the receiver. I have an ARMS SIR handguard on my PRS AR-10 so I adjust the cheekweld to meet the higher vertical position of the scope. Shooting from a standing position is definitely awkward. I like my UBR better for adjusting a desirable length of pull depending on how I'm shooting and have found it more versatile for my uses. If I had a monopod or had a need to utilize the PRS adjustments more I would probably have a different opinion. For dedicated precision/bench shooting I think the PRS would fit your needs best.

The press is great I put one on my fall. It does add some weight tho

I've used both, but ended up going with a UBR because I do not use my AR primarily as a bench gun. It's extremely solid, but I do think the PRS is much better suited for a bench gun. The adjustable cheek and LOP are awesome!

good to know...i'm also debating which to use for my next build

funny I was going to post a similar thread. I'm stuck between the two as well. same thing, 20" set up....

I say get the best of both worlds!

A CTR stock, Riser,and Larue POD combo will have the benefits of both the UBR and the PRS stocks.

Cheapest Monopod I can find is $100. Thats pretty expensive

Ya what the heck! They are so much for what they are it seems...

I think i've decided on the PRS due to the great price I found. I think ill be happier with it since its what I originally wanted. I just figured the UBR would be a nice balance...

Since I wont be buying a monopod any time soon so ill just still with some bags.

02-23-2011, 6:09 PM
I've been trying to find the lowest price on both. what did you come up with?

02-23-2011, 6:48 PM
I've owned a PRS stock, sold it and got a UBR stock.
I've owned a UBR stock, sold it and got an A2 stock and a ton of ammo.

They are good stocks but in all practicality there isn't to much of an upgrade from an A2 to justify the price.

Thats probably true, yet I dont have a stock at this moment anyway.

I have a PRS on my .308 and as nice as it is, I would say save your cash and stick with the A2. As much adjustability as it has, I don't use almost any of the features that it boasts...

Now infant find a 100% answer to see if the PRS is Considered an evil feature? I dont really care Im just curious to know since i have a stupid evil feature on my rifle.
