    Before I put the 9mm in my 10.5, the standard one ran fine. But, it doesn't hurt to lesson the wear and tear by adding key parts!

    On a side note, when are you adding the Sabre uppers?

    Glad I could help.

    I have spec'd out Sabre uppers and complete weapons which are different from what they normally make so it is taking me awhile longer to get what I want.

    I hope to have uppers and complete weapon in a couple weeks.

    Complete weapons will have the following:

    M4 Barrel extension
    M4 flattop receiver
    M16 BCG (properly staked with black insert and Crane O-Ring)
    Mil-Spec Receiver Extension
    H buffer
    ISMI CS Spring

    A lot of these items are small, but no other company builds complete weapons to these specs (not even Colt).

    I will also offer a variety of triggers, rails, stock, etc, etc on them.

    Advise when a complete upper is available, full fsb and standard hg's-the stash is growing mold!

    Has anyone found ammunition to be a variable in reliability when using an ISMI buffer spring? I am using a 10.5" LMT upper with a H3 buffer and ISMI spring, when using Winchester white box or South African ammo it turns into a single shot. Change the spring out with a stock part and it works perfectly. Unfortunately, I didn't have any hotter ammo with me to try out.

    It does not surprise me.

    10.5”-11.5” AR's are hands down more finicky to ammo, lubrication, set-up, and end user maintenance problems. That being said, they can be very reliable for a "Switched On" end user.

    How well lubricated is the weapon? Have you tried it yet with other ammo? How many rounds the weapon fired?

    FYI- I've had great luck with my ISMI spring.

    This is a new upper with less than 100 rds thru it. Haven't used any other ammo yet and lubrication was on the wet side. Haven't shot enough ammo yet to make any real observations just wondered if anyone had a similar experience.

    I may be the sole voice of dissension.. but I ran a standard weight Buffer for well over 12 years in a 16" HBAR Carbine with well over 14K and never had a problem or felt the need to change to a heavier buffer. Heres what it looks like.



    When I finally picked up a new Upper and lower it came with a H buffer. To be honest. After a few hundred rds... I can not tell any difference. and because I switched from a 16" HBAR to a 14.5" M4 profile.. The muzzle jump and recoil feel a little more severe due to the loss of the extra barrel weight I'm sure.

    So, I can't say as I'm sold on the heavier buffers for the 16" and 14.5" carbines. I know the shorter SBRS seem to run better with them. Just my take on it.

    In my carbines I have the following:

    16" middy 3-gun AR = standard CAR buffer
    16" Colt .625 bbl = H buffer
    10.3" LMT SBR = H3 buffer
    13.7" Noveske = H2 buffer
    both 11.5" SBRs = CAR Enidines

    All have ISMI chrome silicon buffer springs (except for my 3gun AR) and all work 100%. My 3-gun rifle now has a standard spring and CAR buffer because I want it to cycle very fast and recoil flat. I run a Colt unshrouded 1/2 circle carrier in this gun and with it's light weight and a AK Concepts DNTC Comp (muzzle brake) it doesn't recoil hard at all. I was running a rifle length buffer and an ACE stock but I'm finding the stock too long so I just installed a Sully stock on it. I wish the coyote brown ones were available so it would match my Gucci 3-gun rifle.
