n4p226r 105 Posted January 14, 2014 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 Posted January 14, 2014 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.

JoeTK37 8 Posted January 15, 2014 So what is it that makes on SPR and another not? Any defining features to special purpose? Quote Share this post Link to post Share on other sites
High Exposure 5,661 Posted January 15, 2014 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 Posted January 15, 2014 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."

n4p226r 105 Posted January 15, 2014 So what is it that makes on SPR and another not? Any defining features to special purpose? 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 Quote Share this post Link to post Share on other sites

If you're willing to sacrifice and get consumer-grade rather than "operator-grade", you can certainly do it for under $2500. 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.

Shane45 807 Posted January 16, 2014 IMO heavier barrels are a hallmark of an SPR because it aids in retaining accuracy when sustained accurate fire is needed. Quote Share this post Link to post Share on other sites

I'm hoping to get a stainless 18" noveske with NSR on mine. 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? Quote Share this post Link to post Share on other sites

Generally it is an accurized "lighter" caliber (5.56/.223) rifle with a magnified optic designed to engage targets at medium range with precision. 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 Posted January 17, 2014 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. Quote Share this post Link to post Share on other sites
Shane45 807 Posted January 17, 2014 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. Quote Share this post Link to post Share on other sites
