Shorter LOP on AR-10?

Hi All,
I've just started in NRA high power with my AR-10 rifle and have found the A2 stock to be too long for off-hand and sitting positions. (I have a small build.) I'd like a "fixed" stock with adjustable LOP (i.e. not a carbine style stock), but I can't find anything short enough (at least 0.5" shorter than A2). (The Magpul PRS goes .25" shorter.) Ideally, I'd like an A1 stock with an adjustable butt plate, but all the plates I've found actually make the A1 longer than an A2 even when collapsed. Any suggestions? The KAC stock is uber over-priced, IMHO, and I'm not sure I can/want to use a "space gun" style stock...
Thanks for the help!

How about a RRA entry stock and ad an adjustable butt plate? You will need to use another buffer/spring since it is designed for the AR15. I think you may run into issues with the length of the bolt and bolt travel of the AR10 with a shorter stock and buffer system that is designed for the AR15.

+1! Da rules is da rules. Once you decide from there...I'd go with the UBR and not think twice. It gives you a much more flexible stock platform that provides the stability of a fixed stock with the adjustment range of a collapsible. See here:

He has already stated that the PRS cannot adjust as far down as he would like. </div></div>

guess i should have read that a little closer then.

Re: Shorter LOP on AR-10?

Yeah... currently I'm in match rifle. My understanding is that an AR-10 must conform to the standard issue m-110 furniture (mine doesn't), and I'm not sure if it also must have an adjustable gas block (mine also doesn't). The M-110 has an adjustable A2 stock (I think) so the UBR/PRS/A1 or anything else would probably not be legal. That said, I'm not really concerned about being competitive - I just want to learn to shoot better and NRA matches are fun! I'll check out the UBR...
Thanks!

Re: Shorter LOP on AR-10?

So, the UBR stock and most other collapsible stocks require a carbine buffer and spring. How would this change affect cycling, recoil, or accuracy in an AR-10? Or maybe a better question is: why do rifle length buffers/tubes even exist if the carbine length would work for all AR-10 applications? Seems that a shorter buffer stroke would cycle faster, increase recoil, and degrade accuracy somewhat...?

The carbine buffer I use weighs more than the factory rifle buffer and actually improves cycling. Some people claim reduced muzzle rise, felt recoil, etc with heavier buffers but it all feels the same to me and I've used one as much as 7.2oz.

Then get a MATCH RIFLE stock. Everything you posted past the part I bolded is irrelevant for Match Rifle.

Look at the Elisio and Holliger (WOP) stocks. When you lower the butt for correct offhand shooting, both can become very very short in LOP with the buffer tube actually over your shoulder.

You might also want to start hanging out on the right web site for the sport - usrifleteams.com - much more useful info there.

+1. With the UBR and one of Slash's Heavy Buffers (he makes 2 different weights for the AR-10/LR-308...one heavy and one extra heavy for use with a suppressor), the AR-10 will function as reliably and arguably smoother than a standard rifle buffer. Accuracy between carbine and rifle-length stocks should be the same...the only difference is the shooter and how the stock "fits" the shooter best between the two. Recoil is such a matter of perception that I won't be so bold as to tell you it will feel like more or less than a rifle length buffer. Recoil is in the shoulder of the beholder.

Well... I hesitate to go with a full-on match rifle stock as they seem too application-specific. I'm competing to primarily improve my shooting skills, and I'd like to use this gun for other types of shooting & maybe hunting. What are the disadvantages of using "space gun" stocks in the field? Weight? Fragility? If I had the money, I would buy/build a dedicated rifle for high power, but for now, I have only this one rifle... Thanks for the link, btw.

You are three screws and 2 minutes from switching between your field stock and your match stock.

I'd be looking at that one closely.

Those are nice stocks! I've seen them on quite a few of the match rifles at our club.

You are better off working out your short comings for offhand with the A2 stock. if you really work your position you will find you will want the stock longer for sit position anyway. and you will need the stock longer for prone. remember 50% of the game is belly work. only 25% is standing, sit and prone is where will will develop most of your skills with natural point of aim and trigger control. remember jrs are shooting A2s and they aren't have to many problems with the LOP.

Re: Shorter LOP on AR-10?

I had exactly the same problem. I solved it by buying one of the older A1 butt stocks. They are one inch shorter.

The problem is caused because the larger receiver of the 7.62x51 rifles is longer. Getting one of the older, shorter stocks will fix it up. They can be had for around $10 from Numrich arms, or whatever that company is called now.
