I was doing some research on it and the whole idea has started to grip my mind. With proper twist, ammo and optic it really truly does extend the authority of the AR to 500 yards and perhaps more.
Anybody here deploy active duty with one in the sand box or know anybody that did? Where and how were they more effective?
As I understand it the unique aspect is the 18" 1/7twist, 77grain smk's and a good variable optic up to 10x.
Anybody doing the 3gun thing with a MK12/SPR style set up?
My only experience is with a 16" and xm193.
My only thoughts are that if you cannot keep the weight down might as well go 308, and also; how are the fellows retaining the ability to do close quarters with the MK12?

I think the SPR as a whole was abandoned by those that wanted it. They figured a 16" precision gun saved weight and accomplished the same thing.
I have a Noveske SPR and a Noveske 16" light weight built as a Rogue hunter. The 16" weighs a pound less, gives up about 50fps and is just as accurate.

I've currently got a heavy 18" barrel for competition, mainly for a smoother recoil impulse and it works fine for what I need. IME in competition an 18" barrel really doesn't give up anything to the shorter barrels on close and fast targets. Actual use in a vehicle and indoors a shorter barrel wins though, IME.
I've seen a guy regularly hit torso sized steel at 400 yards, offhand, with a 16" barrel. So I'm not convinced that an 18" is needed to make an AR useful at 500.

Tom, a 1-7 twisted 16 inch pencil barrel from DD and Colt on my two carbines shoots the 75 grain Swift bullets over 23 grains of TAC really good. The heavy bullets are very good against 150-200 pound game animals. Shooting 500 yards I don't see much, I hunt in Northeast GA and the deer ranges are close to you 99% of the time.

I've never built a MK12 replica but the 18" SPR contour when fluted makes a very nice setup. Excellent ballance and still very light. I've owned a couple SPR's that weren't fluted and didn't really like them as well.

The main problem that I cannot solve in my mind is:
If you go full tilt with a 3.5x10 scope what is the best option sight/redot/irons for close in?

The main reason I have guns setup for different purposes. My SPR complete with a 3.5-10 MK-4 is best at medium to longish range.
My 16" RECCEish gun has a VX-6 1-6 on it. Good enough for close range and good enough for medium range. Though it has the Fire dot reticle that makes it faster than most up close, the reticle is a little too thick for extreme accuracy out far.
My close up house gun is a 16" Colt light weight and wears an Aimpoint Micro red dot on it. Nothing is faster up close but it sucks with small targets past 100 yards.
Given one gun to do all, I'd take the RECCEish gun with the 1-6.

Do you use a compensator on the SPR?
At first I laughed at the idea of using one on an AR but after thinking about it I can see the wisdom of it when you are trying to call your own shots without a spotter... I assume they all but eliminate recoil.
There are 3 million options these days for comps.

TAK, do you know how the BCM comp compares to anything else, specifically the battlecomp? I had trouble on a 16" Middy with the BC overcomping and creating muzzle dip. I wondered if the BCM or Griffin might be a better option.

Issued MK12 MOD1 The SPR has probably accounted for more direct kills in Iraq and Afghanistan than all other individual weapons combined. It was an awesome rifle, but I and those I know realized that we could do the same things with 16in Recce's setup similarly. That has evolved in realizing that a 14.5in free-floated M4 with a 1-6x, 1-8x, or a 2.5-10x (or similer) with offset red dot and good ammo will take the M4 and 5.56mm to its practical limit.

Got any pictures and sources and specs on the offset red-dot set up?
Thanks...
Cool picture

There has been a bunch of different setups. Mostly using 45 degree mounts off the right side of the receiver. The best probably being an AimPoint Micro and Larue combo.
I'll try to get some pics up later....

MARSOC is running the Aimpoint Micros on Daniel Defense offset "one-o'clock" mounts IIRC. They like it with their ACOG's.

SPRs are fantastic, and the MK12 was sweet and relatively advanced for its time -- but as it sits, obsolete. Regardless, I'd love to put together an 18" AR with a Bushnell Elite 3200 up top, and an offset RMR. If you can ruck the weight, it'd do just about everything.

I've put together a bunch of SPRs and SPR uppers for individuals, as well as run them at various ranges and time constraints.
They are truly an excellent platform, and if I was in a static position such as on an embassy detail, where I knew I was going to be doing mostly roof top shots, I would take it in a heartbeat.
That being said, said for an all around weapon, I find that a 16" gun with match grade tube, free floated barrel/handguard setup and a proper trigger such as a Geissele Dynamic to ideal.
Top it off with a low powered variable such a 1.5-5 or 2.5-8 Leupold, or a Nightforce 2.5-10x24 and call it good.

I wondered if the BCM or Griffin might be a better option. All I know about the battle comp is what others have said. A friend replaces an A2 comp on his 11.5in gun and said his shot-to-shot splits got a lot faster. Hope that helps. The BCM is a little over half the price of the Battle Comp and it looks like about half as long, if that matters to you.

I was at the range the other day with some competition shooters and played with several comps and it was an excellent place to learn. I heard the comment about overgassed comps that will dip the muzzle and some liked it because they are counting on shooting from a bipod or hard rest that made no difference. I tried a battle comp, spikes, griffith(not sure which one it was, lots of little holes), Troy claymore, PSA pigsticker, JP tank and the Kaw valley.
I think they all did a pretty good job of cutting the recoil and noticed a big difference in shooter comfort. Behind some of them I could not shut off my blink reflex and cannot imagine deploying one in a confined se. I think my favorite was the kaw valley, not the greatest on recoil reduction but I really like the way it pushes everything out front and makes it quieter for the shooter.
Hunt hard, kill clean, waste nothing and offer no apologies.

I ran a Gill brake/compensator once on an AR. It did what it said it would do but also like every other one I've ever run, it was loud as hell.
Fine for a rifle that you will always use hearing protection with but for one you that you may take hunting etc. I would pass.

I have one I put together with a Compass Lake/MSTN barrel years ago that has been my favorite AR ever since. I have never found the SPR contour barrel to be heavy at all. That rifle shoots like crazy but has recently been replaced as my favorite by a 16" match-barrel-equipped rifle that fits what most are calling the "Recce" description. Mine wears an Apex tubular handguard that's my current favorite and shoots tiny groups with 75-77gr match ammo and shoots 1 MOA with ball ammo.
If I think I'll need to go beyond 400yards or so, I'll grab my 16" .308 AR.
