AR- adjustable stock for long range

[Jeff H]

Doing some upgrading on my M4gery and I'm wanting to maintain the adjustability of the M4 stock but I want something more stable that doesn't rattle around for shooting at distances.

Currently looking at a Magpul UBR. Any thoughts on this one or others that would work? The UBR is rather pricey, but if it is worth it, then I'll pay it.

If you want to retain the quick-adjust LOP of a carbine stock but just want it to lock up a bit tighter, magpul makes a few stocks with a secondary friction lock. I have an ACS-L that locks up fairly tight. The CTR and STR also have friction locks. The CTR also has accessory cheek risers available if you need to raise your cheek weld, but they can interfere with the charging handle.

Yes, I like magpul stuff. They make good kit for the money.

I love the UBR but it's heavy. For a carbine set up for HD, I use a CTR. For a precision AR, I use the Fixed Length Carbine stock made by MagPul

A better fitting stock is one thing, but a sniper stock on an M4 might get you comments from your buddies and casual onlookers at the range. It's done but the return on the money spent won't show you much.

Precision shooting is controlled by the barrel, ammo, and optics first, with shooter skill being good enough to take advantage being necessary. A stock is about at the bottom of the list of effective enhancements and requires fully implementing all the previous items first to deliver it's incremental improvement.

Are you handloading? If not $200 will do more in reloading equipment and you will shoot twice as much as the ammo is so cheap. That's an investment that will return more than a stock will.

I got a UBR recently. If you must have an adjustable stock and you must have a good cheekweld, it's the ticket.

But, it's heavy. I'd probably call it out of place in an M4gery because it would probably make the rifgle butt-heavy, and heavy overall...

OTOH, on a precision AR with a bull barrel, it balances well.

My thoughts exactly. An M4 is not gonna balance properly at all with the UBR on it...

OP,

Have you considered the B5 Bravo or enhanced sopmod? Probably not what you'd normally consider using on a precision rifle but they provide good cheek weld, fit snugly, and maintain pretty good balance on an M4 type carbine. There's very little wobble in mine, and the bravo is pretty light.

May be taking you away from what you want. Just food for thought.

If he's doing longer range offhand shooting (200 yard standing in across the course), a rearward weight bias isn't necessarily a bad thing.

The rear weight is supported on the shoulder in offhand shooting anyway, and in a typical high power shooting posture for standing, it offloads weight from the front, as your support hand becomes a pivot point. This effectively lightens up the front of the gun, giving you a longer time on target without shaking from fatigue. I've loaded extra batteries in the Troy stock I put on my rifle just for this very purpose... to bias the weight back, for offhand shooting.

I have a UBR stock on my 6.8. I guess I didn't notice any extra weight, maybe because it was already a 20" barrel. Lots of choices out there that are better than the mil-spec stock.

I have one on my SPR-gery and I like it a lot. Solid, adjustable LOP, looks sharp...

The Magpul PRS is what you usually see on an AR variant setup for long range. They are adjustable for cheekweld and LOP. HEAVY, but stable. Have a rail for doing a shooting pod on the stock also. You can add a rubber butt pad for even longer LOP.

I like the UBR as well, but an easy drop-in that gives a good cheek weld for me and locks up snug is the ACS-L.

 

[MrCleanOK]

Tirod is right on. Get it if you want it, but don't fool yourself into thinking that a non-wobbly stock will make your rifle significantly more accurate. Accuracy lives in the upper receiver. If stock wobble is causing you to miss shots, you need to work on how you hold the rifle. I have shot enough perfect qualifications with Uncle Sam's rifles to know that stock and receiver wobbles aren't the primary issue.

If you don't take Tirod's advice and you're setting up a SPR/DMR rifle consider using a LUTH-AR stock. I'm using their MBR-1. Adjustable length of pull, adjustable cheek rise and lighter than the Magpul PRS. Not quick adjustable but neither is the Magpul PRS. A good fitting stock makes shooting much more comfortable.
