Post PICs of your SPR style rifles

[n4p226r 105]

Since i just looked and see that it would cost me $4700 or more to build an SPR out of a stripped lower lower parts kit installed, its safe to say that it wont happen anytime soon.  post pictures and specs of your current 16"+ magnified optic ARs!!!!

[papercutninja 24]

Honestly, the optic is what really kills the pricing on these. If you're willing to sacrifice and get consumer-grade rather than "operator-grade", you can certainly do it for under $2500. I built mine a couple of years ago, but i haven't shot it all that much because the Black Hills Mk262 was so expensive that i wanted to get my reloading setup in order. Then Sandy Hook happened and ruined everything for a while. Now i'm looking for a new optic before i shoot it again.

Built it last spring out of parts in the bin. Shoots pretty well for a standard non-accurized upper/barrel.

Wilson has one for about 2400....

Other than that.... To me, SPR tag is a little vague.

I have the LWRC M6 but it's not their SPR model....

So what is it that makes on SPR and another not? Any defining features to special purpose?

[High Exposure 5,661]

The key word is purpose.

 

It is all about what role the rifle was intended to fill. Generally it is an accurized "lighter" caliber (5.56/.223) rifle with a magnified optic designed to engage targets at medium range with precision.

[bhunted 887]

Should have mentioned that the LWRC SPR version of mine has the spiral barrel to lighten the weight a bit which also supposedly helps the barrel cool off faster. Rather than try reinvent the wheel and remember everything, here is their descript..

 

"The new LWRC International Special Purpose Rifle (SPR) is the epitome of a well-balanced and fast pointing tactical carbine. The rifle uses a lightweight sculpted rail derived from our REPR platform. The SPR-MOD rail, at 12” in length, is 33% longer than our Mark II-B rail, but incredibly is still 5% lighter. The cold hammer forged barrel is spiral fluted prior to being treated with our NiCorr surface conversion process. The spiral fluting shaves 20% of the weight off the barrel and relieves the longitudinal stresses that can cause the stringing seen in conventionally fluted barrels. The weight reduction in the front end and the svelte wrist of the user configurable rail, make for an incredibly well balanced rifle.

 

The SPR features our enhanced fire control group. The fire control group and the bolt carrier are coated in our proprietary nickel coating that promotes permanent lubricity and allows the operator to run the gun nearly dry when the situation requires it. The piston system is our mid-length system, which provides a more direct recoil impulse for faster follow-up shots."

Yeah... my SPR-ish build WOULD have been "reasonable"... until I went optic shopping.

Thats ok.... You don't go too cheap on optics. Especially if gun is accurate and no cheap.

you guys are picky with your terminology.  

 

lets rename the thread to SPR/mk12 clone/ Designated marksman style rifle/ etc

 

pretty much narrow it down to an AR 16"-20", magnified optic, and a bipod that you would consider using for longer range engagements than something normally used with a red-dot.  aimed more at precision than fast target acquisition but not a dedicated sniper/benchrest style gun

definitely.  i kinda listed everything on paper without totally thinking it out.  In my $4500 i had $1700 for optics, $230 for a mount, and another $600 for an offset red dot (id probably never do this)  so really i'd be closer to $2500 out the door on the rifle.  

[Pizza Bob 1,488]

Does this qualify? Admittedly, I cheaped-out on the optics, but for all the use it gets, it works fine.

This thread is making me want to build another AR.  Maybe ill just get a 2nd upper and use the same lower...

bull barrel may disqualify you.  judges????

I decided that girth was better than length

[High Exposure 5,661]

Why would a bull barrel DQ PB?

 

Oh, and Bob, I have resorted to that same argument quite a few times before I was married

I recently put the TA11 on her and today was my first chance to get to the range since swapping optics.  I really like it, was shooting just under MOA at 200yds which for me is damn good.  The SSA trigger is helping tremendously with my accuracy.

I don't know. That's why I asked for judges. To me, it would seem a bull Barrel would be suited more to the bench rest side as opposed to the lightweight mid range rifle I picture a SPR/DMR to be

Any reason you went with the kns and geissele ssa? I remember reading his opinion like 4 different times not to use them with his triggers when I installed my SSA

 

That's a real nice rifle though. I'm hoping to get a stainless 18" noveske with NSR on mine.

[Shane45 807]

IMO heavier barrels are a hallmark of an SPR because it aids in retaining accuracy when sustained accurate fire is needed.

I went with the ssa trigger bc I had one in another ar and the pull worked the best for me out of all the triggers I have tried.  I decided to put them in all my ar's.  As far as the kns pins the rifle had them installed already so I reused them when I put the trigger in.  I had not really looked into any ill effects.  Was there a reason stated not to use them?  

[bhunted 887]

According to LWRC, they say the spiral barrel weighing 20% less, aids in quicker movement to get on target.

IIRC some have had reset issues when not using the pins suplied with the trigger.

Hmm, well I will see what happens in the future.  I still have the pins that came with it.  Put about 100rds through it today with no issues.

not to drive the thread off topic.. but I just never understood this.. 

what is "medium" range? and don't "most" mid to upper end ARs perform pretty well in that "medium" range (assuming decent operator and glass)?

[High Exposure 5,661]

It is a classification of AR designated by the military (I actually think the Navy pushed the concept for their NSW folks) to fulfill a requirement that they specified. Basically designed to perform at ranges between a designated sniper rifle and a carbine. Ammo, glass, barrel, glass, stock all designed to fill that role.

 

As far as other carbines remember that the mil-spec TDP is 4-5MOA accuracy. The SPR is spec'ed for significantly greater accuracy standards.

 

The concept was then taken by recreational shooters and applied according to their designs.

[Shane45 807]

Just to break it down a bit further, SPR's were a secondary role for a rifelman should the need arise for somewhat better accuracy requirements in combat. But not a sniper role. Then it seems you have the DMR rifle which is a step up the ladder filling the gap above the SPR rifle and below the dedicated sniper. IMO the DMR steps out of the 5.56 caliber but not exclusively.
