What special operations unit uses a 5.56 KAC?
These are excellent points. Kevin Boland has been very responsive to the questions I've asked. I've read that the KAC bolt will last a minimum of 20K rounds. Pretty good. Won't I outshoot a barrel by that round count? In an e-mail from him, he said that they last closer to 30-40K. Wow, that's a long time. Still sooner or later it will need to be replaced. It's my style to have a back up, so I asked Kevin what the cost is of a spare stripped bolt. He said it's about $250!!That's just the stripped bolt, mind you. No carrier or field kit parts included!!
What I really need to ask myself here is. Is the modified KAC extractor more effective, and the tougher bolt more reliable and durable that it is worth the extra$. The efficacy of these parts, if they are really more reliable, will be difficult to determine. I mean, whose really done a big study/test on it. However, i don't doubt their longevity. If I only need one spare bolt for the life of the rifle, maybe it's not a bad deal.
Another concern I had was the gas block. however, I understand that it is press fit, and they put rocksett on the screws. Should stay in place. A bear to get off.
I think that it's pretty cool that the whole piston thing (SCAR) isn't regarded as necessary for a hard use gun. I have a piston kit on one of SBRs, and I would not say that it is more reliable than my DI ARs. The only advantage is that it is easier to clean.

I'd like to know this too. In fact, the only active KAC rifle in use (that I know of) is the 7.62mm SR-25, and even then, it's standard issue, not a Special Forces-exclusive item. The 7.62mm rifles do not see the same firing regimens as their 5.56mm counterparts, as they are used primarily in sniper applications. Therefore, the use of the SR-25 does not correlate into the SR-15 being "equal" in terms of using it for active duty.

im sure there are some KACs in use... look hard enough, and you'll find some special procurement of just about anything hiding in the shadows.
however... how many colts are there in special operation's hands compared to however many KACs? just because some unit has a particular weapon in their arsenal doesn't mean jack shit, when we're presenting evidence to support our purchases. personally, i don't give a flying truck what "SpecOps" does or uses- not only am i not SpecOps, but we must remember that special operators have do not by default have any kind of expertise in weapon design or manufacture. how many combat arms soldiers have you heard say things to the effect that the AR platform in general is worthless, and that the AK is some kind of masterpiece of ballistic engineering, and similar such ignorant bullshit?
I'd pick the SR15, but you said "hard use" which implies a certain preference for durability over smooth and efficient function. While the SR15 is a fine rifle, the SCAR is built like a brick. The carrier assembly, extra-simple charging handle, etc. seem to make a very robust package.
The SR15, while enhanced in comparison to other AR's, is still bound by the limits of the DI platform (which are minimal for anyone but the most maintenance-free end user, but still, you said 'hard use') when it comes to lubrication, parts breakage, etc.
So, given your criteria which implied a use schedule with an emphasis on reliability, I chose the SCAR. Not my pick over a DI AR, but I certainly would think the odds of one running off-the-shelf for a few thousand rounds without a parts breakage is better than DI guns that can break bolts after 5-10k rounds. Not an issue for me personally, but again, its your criteria, not mine.![]()

From the recent posts it appears my last post was provocative. I do not know of any SpecOps "Units" that use a 5.56 KAC. My posting states SpecOps personnel. SpecOps personnel have used KAC 5.56 rifles. If you want names either ask KAC (good luck) or hope someone who served since KAC 5.56 rifles became available makes a posting regarding his personal use of the rifle. It has been a long time since I spent anytime near Smoke Bomb Hill but one thing remains the same: SpecOps personnel sometimes use non-standard issue weapons and they influence the decisions made on adoption of new weapons technology. I think this will all be OBE in a few years if the AR platform remains standard issue because the E3 system or something very much like it will probably become standard.
Not that I have any legitimate experience to base my vote on, but it's the one I would want most of the three; KAC.
This is interesting:

And that sums up why it doesn't matter. I can find photos of "personnel" using DPMS', that doesn't make them good rifles. Proprietary parts are a killer for general issue weapons as they are next to impossible to service without a good supply chain from the manufacturer. Just look at the MP5 and hate many have for it because of "proprietary parts and supply."
Though it's not by any means a golden rule, wide-spread adoption of a system ensures its serviceability as the weapon system will most likely be supported at least until the end of the contract for that weapon. Conversely, a non-issued weapon that uses proprietary parts is an added liability, as there's no guarantee the company or the support for it will be around in the next decade (or the next year, for that matter).
Nothing against the SR-15, but that's just the nature of things.

Here's another interesting thread.

I think the gas port issue has been addressed. I don't put wolf in any 5.56/.223 I won. One thing that caught my eye was No.6's post. He was having trouble with some Pmags fitting and functioning. He goes on to say
"Contacted KAC, no response.Tried to buy a spare bolt and carrier assembly and other spares, again met with a lack of response from KAC. As in no response to several emails and phone calls."
Every manufacturer is bound to have a problem or lemon. That isn't an issue to me. What is an issue is how they handle it. Kevein Boland has been very responsive to my questions. however, if this is how I would be treated by the main office in Florida, they can forget it! I won't spend $2K on any gun to be ignored when I have factory warranty issues! I can buy an HK for that.
