My SPR(ish) Build with PICS

Post by Arch » Sun Dec 06, 2009 4:20 pm

I'm not a "precision shooter", but can see where the ability to make 400 yard Zed-Head shots would be a tactical advantage. Hence, my SPR(ish) build.

Image

This started life as a standard Rock River AR15A3 (non-chromed lined Hbar and standard buttstock). Here's the spec's now:

* RRA Lower (factory assembled with 2-stage trigger).
* MagPul PRS Buttstock.
* MagPul MOE Pistol Grip.
* RRA National Match Upper with 1/8 (Wylde Chamber) Wilson Air-Gauged Triple Lapped Heavy Barrel.
* Free Float National Match Tube (looks like regular handguards but barrel actually free-floats under the HG's).
* RRA Bolt Carrier (gas key restaked with my MOACKS).
* BCM HPT/MPI Bolt
* GG&G Riser Block
* ARMS #40 BUIS
* Harris #5 Bipod Adapter
* Harris "L" Bipod

The glass is a Leupold VX2 4-12x40mm with AO. I have Warne QD rings on order.

Image

I haven't decided on what type of sling a rifle like this needs. Comments are welcome.

After I get the optic mounted, I need find a factory load that performs well. Advanced accuracy is out of my standard area of interest / expertise ( :oops: ) so recommendations are needed.

Here are a few pics of how the FF tube works....

I think every rifle ever needs a Viking Tactics VTAC II Sling, wide & padded version. Preferably in MultiCam. But, I pretty much just think so because Dave recommended 'em for the carbine, and I haven't even tried mine yet, so there could be something totally better for a precision rifle, I don't know.

But yeah, all else being equal, I'd go with a VTAC.

If you want a factory round that'll do decently at long ranges, check out PRVI's 75 grain match (http://www.midwayusa.com/viewProduct/?p ... ber=790565). It's what I and a friend run through our DCM guns when we're not loading 77 grain handloads.

Thanks!

I'll definitely try the round out. I'm also going to try Hornady's 75gr BTHP Match.

Another vote for the 75gr PRVI match. That's what I shoot in Service Rifle matches.

Looks like PRVI is the poison of choice.

Question...

I researched a little and keep finding people selling WOLF as PRVI....for example...

http://www.ammoman.com/webstore_223.htm" onclick="window.open(this.href);return false;

http://www.ammoman.com/images2/Privi/PRIVI223-1.jpg" onclick="window.open(this.href);return false;
http://www.ammoman.com/images2/Privi/PRIVI223-2.jpg" onclick="window.open(this.href);return false;
http://www.ammoman.com/images2/Privi/PRIVI223-3.jpg" onclick="window.open(this.href);return false;

Wolf is not a manufacturer, they are an importer/distributor.

Is this the same stuff you're recommending?

The Wolf Gold Match is PRVI; not only the same headstamps but the same inspection tags inside.

People look at me funny when I get a box of Wolf out at a match. :lol:

$12 / box is the best I've found so far.

If anyone has a less expensive source - please share!

Very nice rifle, Arch. :)

And I've shot a bunch of PPU 75gn OTM too and it's GTG stuff at a decent price (in my area, anyway).

I thought about taking some pic's around the Christmas tree for my "Arsenal" thread. However, to facilitate fitting all 21 of the firearms in the frame I would have had to move the a lot of furniture :lol: .

The best deal BY FAR is to get 75 gr projectiles from PPU and reload em yourself.

Cost half of what 77 gr SMKs cost and 75 gr Hornady projectiles... but deliver 90% of the accuracy. Way popular with multi-gun/3-gun competition shooters, and I ran them back to back against 77 gr SMKs. While they were definitely not as accurate as the Sierra Match Kings, the price is right.

And they've been shown to be extremely effective in terminal ballistics testing, never mind you can get WAYYYYY faster velocities with handloading. The factory loaded stuff is pretty slow.

Hey Arch, does a non-free float 12" quad rail fit over the free-float tube thats on there? or just standard rifle handguards?

There isn't enough "lip" at the front of the FF Tube for anything other than the purpose built thermoset handguards to work.

I thought a lot about using a quad rial on this build, but decided against it because I have no plans on mounting a light or laser. Additionally, the cost to mount a bipod would have been more than the $10 I paid for the Harris #5 adapter.

LOL!!! How could you give up your Dillon man!

A Dillon press is the most important tool for a dedicated shooter IMHO. I'm still gimping along on my RCBS single stage kit, but I do borrow time on a buddy's 550b whenever I can.

Anyway, factory PPU 75 grain ammo used to be cheap, i bought 1K at $380 in Feb. However, my specific loading has shit accuracy, it's getting 2-3 MOA out of precision rifles that have gotten 0.5 MOA or less with handloaded ammo. Just slightly better than M-193 performance. My batch of factory ammo is dated January, 2009. When hand loading the same projectiles, groups shrunk significantly.

All other reports on the factory PPU from credible sources have shown it be capable of 0.75 to 1.25 MOA depending on the rifle though, so I'll assume because my batch was made during post election rush, consistency suffered.
