Buy, Sell, and Trade your Firearms and Gear.The bolt is CNC machined from heavy duty 9310 alloy steel. 9310 steel has a high core & fatigue strength rating, a high hardenability rating, and when properly treated it is actually about 7% stronger than the "mil-spec" Carpenter 158 steel. The bolt is shot peened (stress relieved) and finished with the same Nickel Boron finish as the carrier.9310 steel bolts have had a measurable reduction in bolt lug shearing vs C158 in the Grendel platform and is why its usage is almost universal in that role. In high bolt thrust applications, it has been the best option for steel bolts. ... by comparison to Carpenter 158, AISI 9310 has several elements present in its composition that are ...Bet it is cheaper too. This, c158 has to be purchased in massive quantities, while 9310 can be purchase in a quantity more reasonable for a small company. Can also hold up to the stress a bolt is put under as well as 158 with proper heat treating. better actually however, the heat treating must be done right.Quoted: As I understand it, Carpenter 158 is a case (surface) hardened steel where 8620 is through hardened. This would allow C-158 to be very hard on the outside to prevent wear and crack formation while the inside is softer and more flexible to prevent crack propagation and absorb shock loads. 8620 being through hardened can either be …The steel used is properly hardened, but I don’t think it’s technically Carpenter 158.

The bolt is Carpenter 158 steel and the carrier is 8620 steel. And it has a Mil-Spec phosphate, matte black finish. The BCG has a shrouded firing pin and works in both full-auto M16s and semi-auto AR-15s.Machined from S7 tool steel and tempered provides the superior strength when compared to MilSpec Carpenter 158. S7 provides a 75% increase in tensile strength, and nearly 60% improvement in yield strength. Rockwell Hardness HRC of 46 provides a 15% increase in hardness at the same toughness comparing to either Carpenter 158 & 9310.Stick with a C158 phosphate BCG from any reputable brand. If you want it to be slightly easier to clean then get a chrome one or an NP3 from Sionics. Avoid nitride ( especially if it comes with a 9310 bolt), NiB, TiN, and most other wiz-piss finishes.
