    M4 feed ramps, mid length gas system, .750 gas block

    These barrels have 5/8-24 thread for use with suppressor adapters.
    Melonite treated barrels have proven to last 30% longer than chromelined barrels and are more accurate.  Hi perf. chamber and barrel allow for ANY factory ammo to be used or gain more  with  handloads.

    Barrel is a lightweight profile 5.56 (1lb 11oz). Steel is 4150 11595-e milspec CMV alloy, Melonite treated barrels have shown to last 30% longer than chromelined barrels and twice as long as stainless while being more corrosion resistant. 

    16" 1 in 8 twist Hybrid 5R rifling, 1/2-28 threaded muzzle(standard for 5.56), mid length gas system, uses a standard .750 gas block like all of our barrels.

    Wylde chamber shoots 223 and 556 ammo and is more accurate
    All barrels have M4 feed ramps
    All barrels use .750 gas blocks
    Barrel  .700- under the guard. .700 from the gas block forward.
    These are lightweight combat type barrels not target barrels. Like all barrels with 1/2-28 threaded muzzles they will not be as accurate as a barrel with a target crown or 5/8-24 thread. Common accuracy with decent ammo is 3/4-1.5" at 100yds, 55gr and 62gr  FMJ can be worse but 69gr SMks can be much better.

    This is a barrel only, it does not include any other parts.

    This is a barrel only, it does not include any other parts.

    NOTICE*** THIS BARREL HAS 5/8-24 threads to keep the bore at the muzzle from swelling like most barrels threaded 1/2-28. The tighter bore at the crown gives better accuracy. Do not use Armalite 308 crush washers, YHM or DPMS 5/8 or 308 crush washers work better.

The  final finish meets or exceeds stainless steel corrosion resistance.  416 stainless barrels .980" in diameter do not meet the 2:1 burst/hoop strength safety ratio required by the firearms industry standards in anything larger than the 5.56.

    These barrels were rifled with another companies button design.  They are very accurate but, the lands are thinner (width not height) than what I wanted and may not last as  long due to thin lands. If you only shoot 30-40 rounds a year hunting they may last a lifetime. No returns

    We have discontinued the 264LBC/Grendel to make what we believe is a better mousetrap. By trimming the 6.8 case back to 1.620-1.625  the Hornady 123 Amax and SST, Barnes 100 and 120 TTSX, 120 TSX. Nosler 100 and 120 NBT and Lapua 100 Scenar can be loaded to the cannelure in a 41mm long 6.8 case to 2.3"and fit in unmodified Magpul pmags or PRI 6.8 mags. Still there is enough full diameter bullet to properly align the bullet in the freebore. Some other 6.5x6.8 versions on the market are full length cases 43mm long and require cutting out the front of the mag to properly load long bullets into the case.
    The SIX5 is the best of both worlds. It has the high BC 6.5 bullets but uses stronger 6.8 bolts, better mags and plentiful 6.8 brass. Performance duplicates the 264LBC/Grendel.

    4150 CMV 11595E barrel steel. Barrels have a Hybrid 5R rifling with 1 in  8.5 twist .
      Barrels have M4 feed ramps, mid length gas system, .800 under the guard, .750 gas block dia. .700 dia from gas block to muzzle.  5/8-24 thread muzzle.

    6.8 bushing dies with a .288-.290 bushing and trimming the case to 1.620" is all that is needed. The chamber has a .297 neck 1.5 degree throat angle for better accuracy and to prevent splitting the case necks from over working the brass. 
    Barrels are headspaced using 6.8 headspace gauges. 6.8 Bushing dies are used to resize the brass, a special die is NOT needed. I will provide loading information with pressure data when the production barrels arrive.

    Due to overwhelming request we are producing 18 and 20" premium barrels, capable of 1/2" groups.

    These barrels shoot either the 6.5 Grendel or 264LBC ammo. The chamber we used was designed specifically to get the best accuracy from Hornady's 123gr SST and AMAX ammo. The Hornady 123 Amax and SST touch the lands in our chamber at 2.310". This chamber will allow loading most bullets (100 Amax, 100TTSX, 100 Nosler, 120 Nosler) to 2.28-2.3" to gain case capacity but not have a huge jump to the lands like the 264LBC chamber. The freebore is very close to a mid spec Grendel chamber. Accuracy is always our #1 priority.

    4150 CMV mid profile barrel. Hybrid 5R rifling with 1 in  8.5 twist . Helical fluting.
    M4 feed ramps, mid length gas system, .800 under the guard, .750 gas block dia. .700 dia from gas block to muzzle
    2lb-0oz,    5/8-24 thread muzzle.

    The 4150 11595E steel Melonite(QPQ) treated barrels we sell will last twice as long as stainless barrels-  60 rockwell VS 28-30 of the stainless. The  final finish meets or exceeds stainless steel corrosion resistance.  Some say 416 stainless barrels .980" in diameter do not meet the 2:1 burst/hoop strength safety ratio required by the firearms industry standards in anything larger than the 5.56. In all of our barrels we only use the stronger 4150 11595 E barrel steel which can have twice the yield strength of common stainless used in making barrels.

    There is a long history of 7.62x39 and 6.5 Grendel bolts breaking. They are without a doubt the weakest link.
    To combat the problem we have done 2 things. 1-Our 9310 alloy bolts have a larger radius at the root of the lugs and the lugs are .002 wider than mil spec. This extra attachment adds apx 24% strength to the lugs.
    2- for those that want the ultimate in bolt strength these barrels will be available with an optional 800 series bolt and extension. The 800 series bolts are the strongest 264LBC/Grendel bolts made. With a design strength of 35720 lbs they are more than twice as strong as most 6.5 Grendel bolts. They have proven since 2009 they can withstand the 6BRX run at 60,000psi. 
    The Lapua Grendl case will rupture before the bolt breaks as long as the receivers are square and all lugs carry the thrust evenly. 
    A hi performance 9310 alloy Grendel bolts calculated strength is apx 16,000 PSI.   If ordering a bolt choose 9310 alloy or 800 series not both.

    Due to overwhelming request we are producing 18 and 20" barrels.

    These barrels shoot either the 6.5 Grendel or 264LBC ammo. The chamber we use should be compared to a .223 Wylde where the SAAMI Grendel chamber is more like a 5.56 NATO.  The chamber we use does not have a "Grendel" type compound throat.
    The chamber we used was designed specifically to get the best accuracy from Hornady's 123gr SST and AMAX ammo. The Hornady 123 Amax and SST touch the lands in our chamber at 2.310".

     -An AR15  full power wildcat based on the 6.5x47 Lapua. Great terminal performance for hunting deer & hogs, possibly the best available on the AR15 platform. The 270AR is a hunting cartridge, mainly designed to get an AR15 shooting the wide 130gr range of .277 bullets. 270 bullets are some of the best hunting bullets considering the balance of weight and BC. 

    A 130gr bullet can reach  2750-2800fps out of the 20" barrel using 8208 and CFE powder. That is equal to factory 260 Rem velocity!   The Berger has a BC of .452 or .492 depending on model, it should make for a great long distance load for those that like to combine target shooting with their hunting rifle.
     

    4150 CMV 11.25 twist, 5R rifling, Target crown, they are not threaded.
    M4 feed ramps, rifle length gas system, .750 gas block
    Melonite treated barrels have proven to near twice as long as stainless barrels and are just as  accurate. 

    270 AR  barrels are only sold with a matching 9310 alloy .800 series bolt, shipping is included.

    Modified 6.5x47 bushing or Custom Whidden 270AR dies are used to form the shortened brass, no fireforming required. Lapua brass will last longer but requires a little neck turning. We recommend using Hornady Creedmoor brass, it is less expensive,  apx half the cost of the Lapua and no neck turning is needed.

    Complete forming instruction and some load data is available on 68forums.com.
