A professional grade 5.56 rifle with all the right stuff and a lifetime warranty
We aren't just going to settle for producing another M4 carbine, we are striving to build a rifle that is more combat reliable and durable. The mid gas system allows more time for the pressure in the chamber to lower making extraction easier, easier extraction means less stress on the bolt, carrier and extractor. The extractor may be the single most broken part, if the extractor breaks the rifle stops running. The mid length gas system also softens the recoil impulse felt by the operator.
We are using a heavier profile barrel similar to the Socom (mil replacement of the M4 barrel), the nitro-carburized surfaces are more corrosion resistant than chrome and since it is not a coating it does not reduce accuracy like a chrome lining can. This chart shows the QPQ/Melonite is superior to chrome or nickle coated for corrosion resistance.
We also designed our own low land to groove ratio hybrid 5 groove rifling just like in our 6.8s to maximize the bore area and used a 1:8" twist ratio to handle all but the heaviest 90gr bullets. The narrow lands in our barrels deform the bullets less which leads to greater accuracy. We have taken extra steps to minimize muzzle swelling found on most 5.56 barrels with 1/2-28 thread, preventing the bore from swelling leads to better accuracy. These barrels were designed for extreme use and are as accurate as any on the market including the high dollar hammer forged barrels. 24gr of RE15 with 69 gr Sierra bullets commonly print 1/2" groups at 100yds with a good scope, trigger and shooter.
We recommend the use of Black Hills ammo 69gr SMK in our 5.56 rifles.
The 6.8
The 6.8X43 was developed as an improved CQB cartridge by the 5th Group Special Forces, it is now very popular with hog hunters because of the devastating performance combined with the AR15 platform.
It has apx 80% of the performance of the 308 in a much lighter platform.
We have designed a 5 groove hybrid rifling similar to 5R with a low land to groove ratio to increase the bore area and lessen bullet deformation which leads to better accuracy, we have found that our 5R Nitro and S Carb. barrels consistently produce 60-90fps more than most SPCII 10 and 11 twist 4 groove barrels with the same loads. Hornady's 110gr HPBTs reach 2600fps from our 16" barrels and normally shoot under 3/4" groups at 100yds, with better shooters groups are 1/2" so they shoot better than some high dollar stainless barrels and most match grade 5.56s . The Melonite(QPQ) treated barrels we sell will last twice as long as stainless barrels and the final finish meets or exceeds stainless steel corrosion resistance.
The 6.8SPCII and 6.8x43 use the same ammo including SSAs Tac loads and Wilson Combats ammo
uses the same size dies, only the throat in the chamber is different.
In order to be more competitive price wise with Stag, Dpms, Bushmaster, RRA and others we now offer a lower cost ER Shaw 6.8 SPC II 11tw/4gr 16" stainless barrel similar to the Wilson Combat match barrel and Bison. All uppers shown here are complete with a charge handle, bolt, carrier and muzzle device.
Pricing on these complete "SPCII Stainless Hunter" uppers start at $550 including shipping, barrels $175 including shipping.
