If you had said you were running a med. or SPR profile barrel I'd of said UBR, but with an HBAR I think the PRS will suit better.

I have a UBR on my 18" LaRue, and I couldn't be happier.

If your rifle mission is essentially as a precision rifle shot mostly from prone or other supported positions, then the PRS is a good choice.
If it's an all-purpose/multi-purpose rifle then the UBR will be more adaptable and usable. |

But i can't carry both rifles at the same time now can i? So I like to keep versatility at all times. I think I am definitely leaning towards the UBR now. |

On 18" you could go either way. I have the PRS on my 20". I would lean toward getting the
UBR on an 18" especially if you want adjustable length stock and want to keep it compact. |

Disclaimer: I don't own either stock ... yet. 
That said, if I were looking to put a stock on an 18" setup the choice would be between the UBR and the Vltor A5. |

Ok...
So you PRS users... is the length of pull you set for prone workable offhand? And vice-versa? Im thinking that if i am going to be switching back and forth between prone and offhand its going to be a pain in the ass to keep on adjusting the stock. Thoughts? And how about cheek weld on either? My EMOD and IMOD have spoiled me in the cheekweld department... my EMOD is like a big fluffy pillow that yanks my facial hair from time to time  I don't mind the loss of hair because of the fantastic cheekweld. So how does the UBR and PRS compare to each other in the cheekweld department?

I have handled both extensively. i puchased a UBR about 6 months ago for a carbine and really like it. I just have not convinced myself to do a PRS..

My two favorite stocks are the Vltor Imod for lightweight / regular carbines and the UBR for anything with any amount of weight on the front of the rifle.
For my 18" I went UBR and couldn't be happier:

We have similar ideas. I have a 18" Saber Defense fluted stainless upper I am changing around. I have a FDE 13" Troy TRX in the mail as well as a FDE PRS on it's way. I have 2 UBR's on other guns and was debating on the UBR or PRS on this. I figure I would give the PRS a try as I am mainly planning on making this a bench or prone shooting gun. If I were going to be carrying the gun around a lot I would have chose the UBR. I expect to get the rail tomorrow(I hope) and the stock should be here Monday. I will get some pics and put them up so you can at least see what the setup would look like.
I could also note that I swapped the UBR and a red dot from this gun to another gun to make the above setup. |

Add some weight to the storage compartments of the EMod, and save yourself a couple hundred bucks.
Batteries work, or if you really want more weight, use lead.

I couldn't be happier with my PRS. I installed it on my 24" stainless bull barrel with a hogue free float tube. I like the adjustable cheek weld, and butt plate.

I've got an 18" Sabre barreled AR and I have an old A1 stock on it. I've had a PRS on there and an ACS, the A1 just works well for this gun.

Call me crazy, but I prefer the A2. Thats my problem on my SPR. I really like the features and such on my buddies SPR with the PRS but have no issue with my A2 stocks and cheekweld. My issue is more with the cost than weight. If they were $100 i would likely have one. I can afford it, its just the fact that I really like my A2 on a full size rifle and im cheap. |

UBR is a full pound heavier than a regular type. This is totally un-needed weight.

On an 18 I'd go URB.
The fact that it is an 18 and not a 20 means length was an issue some where. The URB is shorter. Bill |

Both are too damn heavy for a rifle intended for serious use. I think people that say this typically have never actually owned and shot carbines with the UBR or the PRS. A lot of competitive shooters, run carbines and rifles with UBRs and PRS stocks and are incredibly fast getting hits, if they were too heavy and slowed them down they wouldn't use them, similarly the modern carbine with a UBR is still a much lighter weapon than the battle rifles generation the M16 replaced, and the next Gen 7.62 battle rifles that are in demand today. I used to carry and hunt with an Lithgow L1A1 (wood furniture and 21" barrel about 9lbs) when I was a 13yr old. I find the UBR balances nicely when used on carbines and equipped as i prefer with longer rails. I have used many stocks, M4 standard, Vltor Emod, Magpul CTR/ACS/UBR, LMT SOPMOD and I prefer the UBR for balance and cheek weld on most of my ARs.

Be careful with batteries, as they may leak. Find a reloader and bum some .45 caliber lead bullets. You should be able to get around 12-20 bullets in the battery compartments and add roughly 1/2 pound of weight. If you're so inclined, find a machine shop to turn some tungsten rod for you. That will minimize empty space in the compartments and it'll be heavier than lead. |

The UBR compliments an 18" rifle well. I specifically got one for my Noveske SPR to balance it out (it was really front heavy). The PRS would have been too heavy and not as useful IMO.

My personal preference is for the PRS on 18" barrels, especially if they are of the heavy profile type to balance things out. Plus you have the added benefit of adjusting for LOP and check weld in more detail with the PRS stock.
