    If your goal is durability, reliability, and accuracy then stick with the mil spec. Nobody puts more rounds downrange than the military. It's the most proven setup. If you really don't want the hassle of changing a worn out recoil spring then buy the springco white recoil spring and use an H1 or H2 buffer.

    I doubt your swimming with your rifle, but the springco springs are chrome silicone instead of the mil spec stainless. So in turn once the protective coating wears off of the springco one it could possibly rust in a maritime environment YMMV but I use a springco blue with an H2 and I have 100% reliability with my BCM mid length

    What if it was ejecting at 3 AM?

    1986s4, you have a Colt 14.5" SOCOM barrel which has a .0625" gas port. That is the correct size. All you need to do is run the right buffer (H, H2, A5H2, Rifle) and spring. If running a carbine size buffer (H, H2) that means either a standard carbine spring or Sprinco blue. I don't think the braided G spring (pun intended. Puns should always be intended.) offers any advantage.

    My ejection pattern is a consistent 3:00 pattern.
    Rifle details:
    Colt 14.5 SOCOM barrel
    Colt BCG
    JP enterprises captured buffer/recoil unit. The standard one which they say is a carbine buffer ? I think I read that somewhere.

    The rifle is, to this point, 100% reliable after one year of being built and used. Quality magazines and factory ammo, some steel case but very little. As originally built it had a Geissele super 42 spring and H2 buffer which was also 100% reliable. Upon installation of the JP unit I noticed slightly less recoil and disturbance to the front sight, overall just a little smoother operation. So I do like the JP unit.

    So what do you all think? Is my rifle operating in optimal fashion? My goal is durability, reliability and accuracy. So far, so good..


    Thanks
    I'm going to chime in on this and try a different tack.

    The rifle works with the JP unit and compared to other other spring and buffer combos, it delivers what you find to be a smoother recoil impulse and faster sight picture acquisition for follow up shots.

    Since the rifle as is runs to your expectations, I think what you need to do is define and focus on what you mean by durability, reliability, and accuracy.

    To me, the only questions are what are the failure points of the JP unit? What happens if it becomes 'uncaptured' while in the rifle? Would you even know it while firing? Are you counting on this rifle as your primary HD weapon?

    If I were pondering this decision, I'd rock on with the JP. But I have an SBR for HD that I only shoot to verify function and zero, then clean, lube and put away till next time. All my other rifles are toys.
