These bolts are not made from normal 9310 steel like most others on the market. AR-15 Performance has taken the current AR-15 bolt to the next level by redesigning the lug and cam pin area as well as using a stronger 9310 Vac-ARC alloy to make this one of the most durable bolts on the market. Notice the thicker web between the recess and the lugs and the larger radius at the root of the lugs.
Caliber – 6.8
Finish – Nickel Boron coated by fail zero- Only the bolt is coated. The other small parts (extractor, ejector)are not.
Includes complete assembled bolt only.
3 year conditional warranty from AR-15 Performance
The complete firearm upper half and cartridge fired must be sent in for inspection. Receivers that are unsquare will cause the bolt to carry the load unevenly on the lugs which will cause early failure. Square the receiver face or use Mega brand receivers. Overgassed systems will also cause early failure. Adjust the gas to eject the cases at 3-4 O’clock. Bolt face and firing pin hole erosion due to gases leaking around the primer or primer piercing voids the warranty. Bolts should be replaced around 5000 rounds.
Do not use Remington 6 1/2, CCI 400, Fed 205 primers.
