Long range accuracy AR pistols?

[Malamute]

No harm, no foul Walt. Likely we've all missed things when posting now and then. I certainly have.


I am curious to hear what the guy thats done long range (1000 yards) AR pistol shooing was using for gun setup and loads.

Dogmush, I missed post no 18, that was good, thanks.

I have an complete custom Seekins AR-pistol with two uppers: A 7" barrel and 15.5" barrel. I don't use any arm braces, and I don't use the buffer tube as a buttstock on my shoulder with either set-up. Speer Gold Dot 64 grain Ammo.

Not going to comment on practicality/weight on either set-up, but rather this is what I wanted so I got it. Both barrels are a Rock 7T.

With the short barrel set-up and a Trij optic it is a close quarter self-defense set-up.
NOT LR! Pic is with a different optic - Sightron optic


The 15.5" set-up I have used for LR out to 1100 yards prone with a Harris BR bi-pod with swivel/Notched legs/Pod-Loc and a small field bag under the grip. 69 grain Smacks/TAC/Lapua brass and a rifle scope. Yes it has a solid bottomed muzzle brake. This set-up was used this past July in a 3-day roving LR Tac match engaging 4", 5", and 10" targets out to 500 yards with bonus targets being further. This is a sub 1/2 Minute AR-Pistol. Dan, my partner used this for the Carbine targets and I used a bolt specialty pistol for the LR out to 1K with bonus targets being longer.
Dan went prairie dog shooting before the shoot this summer with this set-up to just get some trigger time in with and took a prairie dog at 640 with it.
This is the way I have chosen to "skin the cat" for distance shooting with an AR-Pistol.

Hope this answers some questions about what can be done.

Excellent, thank you! Yes, thats exactly what I had in mind.

I switch the muzzle brake when going from short to long mode.

This is a earlier picture at a yearly church steel shoot I put on for my congregation. Leupold VX-3 LR/T with Holland's ART Reticle

Good picture, with the XP pistol in the background.

Glad you like it.
That is a 6.5x47 Lapua XP, shooting 130 grain Berger's

 

[Malamute]

Do you have any experience with the 6x45 in AR's or XP's? The 6.5 Grendel could be useful also, though I dont know a lot about them at this point.

 

[xphunter]

Nope

I have a 6x45 center-grip XP, but have never shot it yet.
Will probably sell it though.

I had a 16" 6.5 Grendel upper that was an easy 3/4 MOA with handloads. I don't see any reason 2" less barrel would do much to the accuracy. You can always get surprised by the unseen, but it ought to work well. I sold the 6.5 in an ill considered attempt at caliber consolidation.

XPhunter do you shoot that with your cheek on the buffer to get the right eye relief for the rifle scope? Kinda hunched up behind it? Looks like it would be fun, if challenging.

Wasn't shooting in that pic.
