In one sentence. - perfect cheek weld.
But for those that would like more detail:
If you are looking for a drop in, precision-adjustable butt stock for AR rifles with A1/A2 fixed stocks I'd not hesitate to recommend this one based on my experience with one I purchased 2 years ago. There are a lot of different accessories for the AR15 series firearms, and though I wasn't wanting to put together "frankengun", I did want a stock that had a means of adjusting the length of stuck as well as comb height for the perfect alignment of my site choice, which was an EOTech.
Every shooter is physically built differently, male or female. I'm as tall as many guys, but my arm length doesn't compare and my shoulders show my more delicate bone structure. So adding something like the Magpul PRS is well worth it if you have other than normal length arms, neck or sighting requirements. Compared to the A2 stock, the PRS can shorten LOP (length of pull) by .25" or extend it by .75" as well as provide three-quarters of an inch of comb height adjustment.(the height so that when you plant your cheek onto the stock, your eye is lined up just where it needs to be to line up with the reticle.)
I couldn't say that this was intended for "close quarters" use, but for "sniper style" range practice for proficiency, this is an excellent addition.
Aesthetics - there's no getting around it, this just looks cool, and it's built like a tank, with aluminum butt-plate and alloy steel adjustment shafts that will withstand a lot of impact abuse (all aluminum components finished with MIL-A-8625F, Type III, Class 2 hard anodizing). But looking good and being strong will only get you so far, it's got to FUNCTION well as designed. The unit will fit most AR/M-4 designs and I've personally used one on a Bushmaster as well as my Wilson Combat Tactical AR-15 (otherwise known as "Vera"), which is what is pictured here.
I have the gunsmithing skills of Barney Fife and I could do it. The hardest part was removing the OLD stock As a direct replacement for an A1 or A2 fixed stock, you simply loosen a couple of screws on the Magpul and slide it over the existing buffer housing, pop off the rubber recoil pad to put the screw back into the end of the buffer housing and there you are!

Adjustments - The adjustments are machined aluminum a knobs with positive-locking click detents so they stay where you wanted them to under recoil as well as allow tool free adjustments by simply rotating the knobs. In my early days of small plane flying there was one manufacturer that replaced their airplane engine control knobs with these brightly colored plastic knobs. We'd say "Acme Aircraft, now with deluxe C.P.S." (cheap plastic S&#t). When one of those broke off in my hand at full throttle, I was less than impressed. So I'm NOT a big fan of cheap plastic anything when it comes to something that may or may not keep my alive.
I'm sorry, but I can't read "Butt Padd" without thinking of those Frederick's of Hollywood ads which were in the women's magazines when I was a kid, which is just wrong.
There's also Front/Rear - 1.25" aluminum sling loops (left-right reversible). For myself, I think I'd just add a good quality monopad to the provided bottom Picatinny-type rail to it. Whatever you do, you're going to see some good off the bench groupings.
