    KAC SR-15 E3

    So I've been hit with the bug to drop a pretty penny on a nice 5.56 rifle. I already own a DDM4V1 LW, which I love and love the fact I can pretty much swap out any parts that I may need to with milspec parts, so now I'm looking for something a little different. I've been up in the air with what I want, along with the KAC SR-15 E3 I've been considering a SCAR 16s (I have a 17s), LWRC SPR (with ambi controls), Noveske w/switchblock or possibly LMT MRP.

    LMT MRP & Noveske are pretty much only honorable mentions as the weight and balance turns me off, both are probably the most accurate of the bunch but I'm looking for lightweight. I currently own no NFA toys, but in the not too distant future can see myself setting up a trust and purchasing a supressor (something to consider which rifles would run the best suppressed).

    The SCAR, LWRC & KAC were pretty much at the top of my list and all have the proprietary parts. At this point I'm leaning towards the KAC as it felt great in my hands when I picked it up at the LGS a few weeks ago. It lacked the rear ambi sling attachment, but from what I read this was a KAC goof up that has since been corrected.

    So my questions regarding the KAC:

    1. I understand the E3 bolt has a life of 20,000 rounds and replacement bolts are very expenisve (like $350), but is the BCG also proprietary or is it milspec?

    2. Is there any known issue with KACs & Pmags? This is one of the things that turned me off about the SCAR 16 is pmag issues.

    3. Does KAC sell SR-15 E3 Mod 1s with Giessele trigger installed or is the only option the KAC trigger? Reading some of the reports on this forum and others about the lack of durability w/ the KAC trigger would be the main reason I'd be looking to replace it.

    Carrier is normal, my KAC lower has no problems with pmags, and they only use their own trigger. And that trigger is almost as good as a SSA and it's much better than a new LMT 2 stage. I don't know about durability though.

    Have owned both the SR and the SCAR. They bring different things to the table, but the SR remains my preferred solution to any problem requiring the punching of holes therein. No issues with the bolt. No issues with PMAGs. No issues with the trigger.

    To clarify, I've tried USGI aluminum mags, Gen M2 and 3 pmags, and Lancer AWM mags and all drop free on empty.

    I've owned and used a bunch of rifles including the SCAR 16 and LWRC M6A2 and I prefer the KAC SR-15 E3.

    I have both an SR15 E3 and a SCAR 16s.

    The SR15 E3 is by all means "the" AR15 to own. The trigger is above average, the lower is above average, hell, everything is above average.

    I prefer it to my SCAR and I really like my SCAR.

    This summation is above average.

    My thoughts are reflected here as well. Out of the box there is not another rifle that brings to the table as much as the Sr15. Just buy it and you will not regret it.

    I have a SCAR-16 and a few SR15s.

    The SR15 strikes the best balance between weight, bulk, and a system that takes recoil out of the equation for multiple shots.

    As said, it's really the AR to own. Also, when you add up all the things you get with it, I always felt it was a cost effective package.

    FWIW, I think the 2 stage trigger is very good. I have never heard anything about it not being robust or durable.

    I own 2 BCMs, 2 LWRCs, and 1 DD. All are awesome guns. If I could pick one rifle today, though, it wouldn't be any of them. It would be an SR-15. They're just an all-around superb rifle.

    And if you're worried about parts commonality (I am too), don't when it comes to the KAC. Despite the bolt being proprietary and requiring a special chamber, the KAC chamber is also compatible with mil-spec bolts, so you always could put one in if needed. Everything else that matters (carrier, buffer, FCG, etc.) is also mil-spec compatible.

    With regards to the trigger, I prefer an SSA. If you do too, buy one from Midway or Brownell's, put it in the gun (easy to do), and sell the KAC trigger in the EE.

    There. All your problems are solved. Buy one. Now.

    Having owned or still own all the rifles you listed, I agree with what everyone else is suggesting and would put the SR15 at the top of the list out of the choices.

    Also, I would give the KAC trigger a shot before you consider swapping it out to a Geissele, it may just surprise you a little bit. If I were to compare to it any of the Geissele's, it would compare to the SSA from my personal opinion and use of both.
