The new #1 deer and hog cartridge
AR Performance as a parts manufacturer selling direct to the public is committed to providing the best practical performance in the AR15 platform at a decent price. Better exterior ballistics, terminal performance, accuracy, velocity and long life are all possible with redesigned chambers and high performance hybrid 5R rifling in Melonite treated 4150 CMV barrels. We machine the strongest AR15 bolts made and several efficient muzzle devices.
Nexgen MSR 308/260
The next generation of 308 sized platforms. Finally an option for those too heavy to carry DPMS LR rifles sitting in the back of the safe. For years many have said they wish there was an AR12. A rifle bigger than an AR15 but without the weight of the AR10. In 2009 I designed a "12" more or less. A 7lb 16" barrel 308 rifle is possible. Standard 308 Pmags can be used in DPMS style 308 lowers. These Nexgen uppers can be built to fire any 308 based cartridges or cartridges based on the 6.5 Carcano (.450" dia case). The 6.5 x 45mm and 6.8 x 45mm wildcats may make a decent GPC for the military.
We will sell kits which include an upper receiver, carrier, bolt and barrel. In addition to that you will need an AR10 charge handle, your choice of any AR15 handguard/rail, gas block, gas tube, AR10 firing pin, AR15 cam pin and cotter, flash hider or comp.
308 and 260 versions avail. fall 2014. Rifle above weighs 7lbs 10oz as shown with a fluted 20" 6.5x47 barrel.
We will produce the billet receivers, carriers(BCGs), bolts, barrel extensions and barrels. All of those parts are specific to the Nexgen and will be sold in the beginning as sets, other caliber barrels later. All of those parts should run around 900-$950. That is apx what you can buy the same DPMS LR308 parts for. You should be able to buy the rest of the upper parts including a $180 rail and have a complete upper for $1200. A complete rifle should cost apx 16-1800, considerably less than any LMT, Larue, POF, LWRC or Knight some of which sell for almost $4000.
Available in limited quantities for the AR15, a .277 caliber cartridge capable of propelling 120 gr bullets over 2900fps and 130gr 270 bullets to 2800fps out of AR15 20" barrels. It is apx 200 fps faster than the 6.8 making it a full power hunting cartridge usable in the AR15. It is based on the 308 case. Shortened Hornady 6.5 Creedmoor cases, Win 308 cases or 6.5x47 Lapua cases work best.
Whidden Gunworks is making custom dies for the 270AR, avail through our store.
We have discontinued the 264LBC/Grendel to make what we believe is a better cartridge. LWRC has developed a new lower receiver that uses Magpul pmags and allows loading to a 2.3" COAL. This has allowed us to design a chamber 41mm long based on the 6.8SPC. 6.8 bushing dies are used to neck down the case then the cases are trimmed to 1.620". That lets the popular 6.5mm 123gr Amax and SST to be loaded to the cannelure. I believe this combination corrects all the problems with the wider PPC case used in the Grendel/264. The bolts are stronger, extractors are stronger and easier to find, Magpul mags feed better than any others. Hornady, Federal, SSA/Nosler and Remington makes brass. There is no need to hold the max pressure down to 52,000 PSI to keep bolts from breaking. The hoop stress around the chamber is less due to the cartridge being smaller diameter than the Grendel. In addition we use only 4150 11595E gunbarrel steel to increase the strength around the chamber over the weaker 416R stainless. A normal AR15 lower receiver may be used, some steel mags like PRI allow loading to the same length as the Magpul mags. The performance will be apx the same as the Grendel/264. Coming mid 2014
The 6.8X43 was developed as an improved CQB cartridge by the 5th Group Special Forces. The devasting performance combined with the AR15 makes it the #1 choice of hog and deer hunters .
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 Melonite QPQ 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 near 1/2" so they shoot better than some high dollar stainless barrels and most match grade 5.56s . Hornady's 120gr SST and Federal's Fusion 115gr work very well on deer and hogs. With handloads it is possible to push a 100gr Nosler to 3000fps from a 16" barrel, nothing else with a 16" barrel comes close to the performance of a 6.8.
The 4150 11595E steel 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. 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. We only use the stronger 4150 11595 E barrel steel in all of our barrels.
The 6.8SPCII and 6.8x43 we use shoot the same ammo including SSAs Tac loads and Wilson Combats ammo uses the same size dies, only the throat in the chamber is different.
