    Looks good in the dessert color. These are tempting.

    Looks like a lot of rifle for the $. If ca wasn't so restrictive I'd snap one up. No need but I've only had great experiences with Bill's products.

    Super duty is superior to the LE version.

    The Civilian version has better rail, trigger, charging handle, muzzle device, and barrel.

    The LE one is a mil-spec rifle in which Geissele made all the parts.

    I ordered one of the Super Duty Rifles since they were on sale with a great price reduction. It has a lot of upgrades over the LE version, primarily a CHF barrel instead a button rifle on the LE, muzzle device, and trigger.

    Selling an AR in my “war chest” which upgrades me to a Super Duty for no additional cost The wait begins to see how long it will take them to ship.

    Did you mean to say that the pin through the bottom of the gasblock is for alignment?

    Did you ever decide on either the 10.3 vs 11.5 Kac? I have the 11.5 cqb sr15 and debating if I should get the 10.3 super duty now as well....TIA

    Yeah I’m in the 11.5” camp now for sure. The extra 1” of barrel gives roughly a 40% increase in dwell time (per BCM founder Paul Buffoni). This results in much less wear/tear on bolt carrier group. As well as smoother operation.

    The problem, just like with 10.3” barrels, is that the overwhelming majority of barrel makers over gas their barrels to accommodate cheap/crap ammo and allow the weapon to cycle. The max gas port on a 11.5” should be around .069/070”...and that’s for mostly unsuppressed shooting. .065” (give or take) is the starting point for a dedicated/mostly suppressed rifle.

    Thanks I really appreciate the feedback. Though tempting , I will stick with my 11.5” CQB and 11.5’’ as the minimal barrel length on future purchases. I plan to run these suppressed and un suppressed equally.

    10.3” guns are fine if the gas port is no more then .070” and you want the shortest/most reliable combo in 5.56. But if you don’t mind the extra inch of barrel, there is an advantage in the guns mechanics.

    Thanks so much again, while I am tempted to try a 10.3/10.5 I will stick to 11.5 and just only an 1” or so more. Really appreciate the feedback.
