6.8/Valkyrie 9310 Superbolt
Items Remaining:out of stock

Works in the 6.8 SPC and 224 Valkyrie (except Wilson Combat) according to their tech they use a barrel extension that is smaller than mil spec extensions and the superbolt lugs being larger will not pass through cleanly.

Bolt is dark gray, mag phoshate treated(mil spec)

Our bolts are not just a normal AR15 bolt design made from 9310 like most of the others on the market.

We have taken the current AR15 bolt to the next level by redesigning the lug and cam pin area as well using a stronger 9310 Vac-ARC alloy to make this the most  durable bolt on the market that will still work will mil spec barrel extensions.  Notice the thicker web between the recess and the lugs and the larger radius at the root of the lugs.  We do not stake the cam pin hole, in 10 years we never have. I just assume anyone building a rifle should know the extractor goes on the same side as the port door.

This is a complete bolt only. It does NOT include any other parts.

3 year conditional warranty
 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 with any high pressure AR15 cartridge.
Warning: Remington does not recommend this primer for use in the 17 Remington, 222 Remington, 223 Remington, 204 Ruger, 17 Remington Fireball. Use the 7-1/2 Small Rifle Bench Rest primer in these cartridges.
This 6-1/2 Small Rifle primer is primarily designed for use in the 22 Hornet.
