Ok let me begin with my intent...Im building an SPR clone for use in the 200yd plus arena...basically an accurized AR with 18" barrel.. I already have a shorter AR which is my run-n-gun tactical baby....Im basically following the Mk12 SPR build sheet (but modified as much as possible to my budget)..I don't have the cheddar to build a true Mk12 but looking forward to using the vast AR parts market to build my own.. so fire off any advice you may have for anyone that has built one or did some research..time is not a big factor as I probably won't be able to pay for everything up front...Here's what I have so far (with my preliminary budget price next to it)

 

LOWER- already have a Spikes Punisher lower ready

 

LPK -thinking CMMG LPK $60

 

TRIGGER- thinking Geisselle Super two-stage. $210

 

UPPER - BCM? only going by reputation would consider other quality ones $100

 

BCG - toss up with BCM/LMT/DD $160

 

BARREL 18" SPR profile looking at Beragara/White Oak / BCM $300

 

MUZZLE DEV. AND GAS BLOCK - PRI OR YHM Gas block with integrate flip up sight

Haven't really looked into muzz devices yet $200 for both

 

HANDGUARDS- only specs I have are round free float modular...I've seen PRI/KAC and MI $250

 

STOCK - Magpul PRS or fixed rifle stock, will also consider regular A2 stock $70 - $200 for PRS

 

CHARGING HANDLE - like the PRI gasbuster but would probably be happy with BCM GF $45 -$100

 

BUIS - not sold on any one yet... $80

 

OPTIC - here's where I know crap about nothing ... Probably would like to be in the less than $400 range

 

shoot away folks with comments,criticisms, recommendations etc..I only have the lower right now and haven't committed to anything else yet...Thanks NJGF-ers

Bump....nobodys rocking an SPR?...

LOWER- already have a Spikes Punisher lower ready

 

LPK -thinking CMMG LPK $60  I have loads Want one?

 

TRIGGER- thinking Geisselle Super two-stage. $210  Nice but not necessary for starters

 

UPPER - BCM? only going by reputation would consider other quality ones $100

 

BCG - toss up with BCM/LMT/DD $160  Wait! maybe you don't need a bolt

 

BARREL 18" SPR profile looking at Beragara/White Oak / BCM $300  Shilen Match w/ a matched bolt about same price

 

MUZZLE DEV. AND GAS BLOCK - PRI OR YHM Gas block with integrate flip up sight  Go crowned barrel!

HANDGUARDS- only specs I have are round free float modular...I've seen PRI/KAC and MI $250  Too much money.  Can get cheaper aluminum floaters

Here's the deal...I got the tee shirt, can set you up on lots of stuff and probably save you some $  here's my rifle and I may be convinced to let it go for a reasonable price.

BARREL 18" SPR profile looking at Beragara/White Oak / BCM $300........WOA..RAINIER....WHY BCM IF YOU WANT ACCURACY?

in the above

Thanks Rutgers and Old School..great stuff guys and I will look into each suggestion..do you guys recommend going with the .223 Wylde chamber or will Regular mil spec work fine?

 

Ps Old School I will PM ya about those items when I finalize my specs..thanks!

Regarding chamber... do you intend on hand loading and do you require pin point accuracy?  If so standard .223 Rem.

Regarding chamber... do you intend on hand loading and do you require pin point accuracy?  If so standard .223 Rem.

I only plan on using factory ammo at this point and don't require hyper accuracy.

Which model MK12, Mod 1 or Mod 0, very different on the upper. I have a brand new Geisselle SSA I would part with for $190. Ww can meet at CJ if you like. If you are building on a budget and you can't shoot suppressed save money on the charging handle, no need for a PRI. Wilson Combat has milspec BGG's on sale for under $100 and also had some barrels on sale last week check their site. 

There are a million ways to skin this cat.

 

 

BCM 16" upper with standard midlength barrel, FAC556, BCM GF CH, and standard BCM BCG ~ $600

DD Omega 9 FF rail ~ $200

Defensive edge lower with STAG LPK, MIAD, and Geisselle SDE trigger (trigger added after photo was taken) ~ $325

Magpul PRS stock ~ $200

TD bipod ~ $100

Trijicon TA01NSN 4x ACOG in a LaRue mount ~ $400 (bought it used)

 

 

 

Photo is 10 rounds of Federal TRU HS SP 64gr from 100 yards, prone while sighting in. I have gotten used to the rifle and it shoots a bit tighter now.

 

I would love to swap the upper for a LaRue Stealth 18" upper but this shoots better than I can, so I don't see any reason to switch right now.

fine shooting!  my bcms' like the heavier than 55gr as well

Nice HE!..does that FSB interfere with optics in anyway?..i was gonna go with an integrated gas block/flip up ala YHM...also realizing I got a little cute with some of my specs and could probably trim some..

The FSB completely disappears under magnification. You may get a slight shadow in the tube in bright sunlight, but I don't even notice it.

Here is the link to the Wilson Combat bolt carrier assy.

On sale for $99.

 

Hope that helps.

Thanks for th info boys..keep it coming..wish I had the $chadols to put it together quick but 3 kids and inquisitive wife force a longer build

LOWER- already have a Spikes Punisher lower ready

LPK -thinking CMMG LPK $60 Check out Palmetto state armory. Their lower parts kits a g2g, and you could get them with geissele trigger, but they are currently out of stock

TRIGGER- thinking Geisselle Super two-stage. $210 I would go with the ssa-e its a little lighter 3.5lbs and has a more crisp trigger break. Candy cane vs carrot breaking is how Geissele describes it. They go for 230 but i got it for $205

UPPER - BCM? only going by reputation would consider other quality ones $100 Any upper from a reputable company. ex BCM, cmt/stag, mega, novekse, seekins....

BCG - toss up with BCM/LMT/DD $160 Any of those are g2g add rainier arms to the list also

BARREL 18" SPR profile looking at Beragara/White Oak / BCM $300  All 3 are g2g.  WOA seem to be hard to get though. Rainier arms also has their own line of barrels that are suppose to be really good.

MUZZLE DEV. AND GAS BLOCK - PRI OR YHM Gas block with integrate flip up sight  Both of those seem g2g. Or you could get a low profile gas block and run a front Buis on top of the handguard
Haven't really looked into muzz devices yet $200 for both I have the fsc556 it works well.

HANDGUARDS- only specs I have are round free float modular...I've seen PRI/KAC and MI $250  ​Personal preference get what ever looks and feels the best to you.  I have a Noveske NSR 13" its very light and pretty small i really like it.  Bcm just came out with a new rail the kmr (key mod rail) pretty much the same thing as the noveske nsr but is suppose to be even lighter.

STOCK - Magpul PRS or fixed rifle stock, will also consider regular A2 stock $70 - $200 for PRS  I had the Prs and it just wasn't for me.  I just run a Fixed carbine stock on my spr type rifle

CHARGING HANDLE - like the PRI gasbuster but would probably be happy with BCM GF $45 -$100 I have the bcm charging handle and I like it. Another option is the rainier arms raptor charging handle.

BUIS - not sold on any one yet... $80  The magpul pro buis look pretty nice. Also bcm is coming out with a new buis that looks nice

OPTIC - here's where I know crap about nothing ... Probably would like to be in the less than $400 range   I have the vortex viper pst 2.5-10x32 first focal plane.  Great scope for the money, ($799 can get it closer to 700 if you shop around) has alot of features.  They also have a 2.5-10x44 that isn't first focal plane that goes  for 599 and has all the same features.  Vortex has a bunch of different lines of scopes that are more in your price range also.  They also have a really good warranty definitely worth taking a look at

Ok moving along nicely...I quickly realized that building a true copy of the MK12 SPR Mod 0 would cost ALOT of cheddar....$350 for PRI FF handguard...$180 for front sight gasblock...$150 for PRI rail...$200 for ops inc brake..$350 Douglas Barrel....Sooooo...here is what my budget allowed..

 

BCM Upper

Rainier 18" SPR Match barrel

YHM Gas block with flip up sight

Spikes Lower

Geissele SSA

YHM semi smooth FF handguard

 

Now onto the stock

 

Originally wanted plain Jane A2 stock but found I am not a fan of the A2 LOP

 

So my options are: (staying in the sub $100 price point)

 

A1 Style stock...finding a good milsurp or go with a new A1 from Fulton

http://www.fulton-armory.com/buttstockassemblygroupa1newblack.aspx

Ive heard some rumors that these were actually Cav Arms stocks with new hardware but cant verify

 

Other option is the B5 Sopmod Bravo...like the cheekweld...like the price point...mostly great reviews...don't need the battery storage in the Enhanced.

 

Any suggestions or experience with these stocks??

I'm looking at slowly building a SPR. Wanted to go 308 put my pockets do not go that deep at this time. I haven't spec out much but I like the luth-ar stock.
