    I assume means the SF one.

    They were in stock yesterday earlier and when I posted. Not sure if it was just yesterday or they had been there for a bit but they definitely had some.

    How much does the SF BCG weigh comparative to the other BCG?

    God Bless,

    I'm talking about the Surefire OBC (Optimized Bolt Carrier), not the LMT EBCG. Finding the latter isn't an issue, the former not so much.

    Seconded.

    With modern manufacturing process, is it possible to build a better bolt that lasts ~50Kish (same ammo as what .mil is using) while still being cheap enough to justify(around $100-$150)?

    Feels like that's what we need.

    I tested the OBC in a select-fire rifle and found that it did reduce the rate of fire significantly. I figure this was due mostly to the increased travel afforded by the design. Unlikely that I will find my notes but my mind is telling me from 875 ish to 720 ish. I mean you could clearly tell the dif just shooting it but the PACT timer gave the real numbers.

    Interesting. I can't remember what Sullivan and SF claimed during the initial hubub regard ROF, but that's a significant reduction.

    Thanks Ned.

    Ran across my data yesterday.

    Rates of fire on auto. 20" bbl, rifle gas, XM193 ammo, carbine lower, indoor range, Pact timer set to give rate of fire.

    895 standard BCG, standard buffer, suppressed
    816 change to H3 buffer, suppressed
    810 change to Surefire BCG which includes their buffer, suppressed. Note says "maybe less gas in face". (All are 5-6 rounds bursts so maybe not the best for detecting this)
    612 back to standard BCG, unsuppressed. Buffer not noted but I suspect still H3
    559 Surefire BCG / buffer, unsuppressed
