12 Best AR-15 Bolt Carrier Groups (BCG) - Pew 8620 vs 9310 vs Carpenter 158 vs S7 Tool Steel �� SOF Arms

First off, full-auto BCGs are legal and dont magically make your AR-15 automatic firing. The slightly longer and heavier bolt carrier group has an additional lug at the rear of the bolt carrier group. BCG Shroud, AR15. On a full-auto AR-15 or M16, this rear lug pushes the sear release downwards which allows full auto (or burst) fire. 21 Best AR-15 Rifles - Top AR Brands Reviewed for 2021A good checklist to look for is in the material used, with 8620 steel being mid-shelf, 9310 and Carpenter 158 steel considered more top shelf, and those made of S7 tool steel the good stuff kept behind the counter. 86l20 Vs 8620 - travelusandcanada86L20 Cold Finish Bar Steel. Alro stocks 86L20 Cold Finish Bars. 8620 is the most widely used carburizing alloy. The "L" is a lead additive to improve machinability.

Their top of the range model is silver colored and comes with a nickel finish. Its carrier is made from 8620 Tool Steel and the bolt from 9310 steel. Alternate material for Carpenter 158 - Practical MachinistCarpenter 158 is just ANSI P6 steel. Perhaps look for a P6 supplier instead? Perally if I was making a new AR-15 bolt I'd go with S7 should handle the stresses of the firing cycle alittle better. But probably also more expensive. Other then BCM and DD I don't think anyone else (except for Colt) makes them using Carpenter 158 anyways. Best AR-15 Bolt Carrier Groups in 2021 - Rated BCG 8620 vs 9310 vs Carpenter 158 vs S7 Tool Steel �� SOF ArmsSteel. The main concern with a bolt carrier group is the type of steel its made out of. Carpenter 158 and 9310 steel are the best materials for the bolt. And 8620 steel will work with the carrier, though its not strong enough for the bolt.

Carpenter 158 Vs. 9310 - M4Carbine.net1 (100%) I've read about this in a few different places, the jist of it is that 9310 is easier to procure, easier to machine (as opposed to injection molded for c-158) and only something like 3% 'weaker' (as in malleable) than carpenter-158. This is strictly going off of memory and I am no SME on it so take it for whatever you think it's worth.

Enhanced Bolt Carriers - Part 1AISI/SAE E9310H is a high pitchline velocity gear steel developed during WW II, not a tool steel. It replaced AISI/SAE E3310H 'Krupp Modified' steel because it possessed higher fatigue life and strength, with lower alloy content. Carpenter 158 is a close derivative of AISI/SAE E3310H.

Faxon Gunner Ultra-Light Bolt BCG RECOIL

MIL-SPEC or improved materials are used through the complete group. The bolt carrier is 8620, fully heat-treated.

9310 is slightly stronger WHEN it's processed correctly. The M60 bolt is 9310 steel is allowed to be case hardened or nitrided. The M16 bolt is supposed to be C158 and is supposed to be case hardened. Nitriding can come close to the temper temperatures and maybe one steel is more sensitive than the other.
