Friggin great rifle. My thoughts on the SR-15: https://www.m4carbine.net/showthread.php?p=480528

Yeah I absolutely love mine. I feel that its an absolute great system. The only thing I feel the need to add is an optic. It shoots better than I can...as of right now:D. Just a little story when I was sighting in with just the irons, I got it dialed in and at 25 meters had a 5 shot group easily into a 3/4" group with of course a nice flyer at the end. It is very light and easy to manipulate. I'm not saying they are the best you could get, as this is my first AR, but I am absolutely satisfied. You won't be disappointed if you decide to turn the key on one.

The best DI AR-15 on the market. IMO.

I've shot a lot of ARs, but KAC makes my favorite DI one.

+1 on the KAC SR15 E3 being one of the best AR options out there. It is by far the favorite rifle in my collection.

I understand they have some proprietary parts, are they reliable enough for that not to be a worry?

The real notable proprietary part (bolt) is of such a design that it is inherently more robust than the "standard" AR design.

In the event something breaks, I'm sure KAC will be more than willing to take care of you.

I think its the best off the shelf AR you can get provided you want a spruced up AR to begin with. If all you want is a simple AR there are better options. If you want an out the box gun that is truly setup to do nearly everything then its the best out of the box choice.



Add up the features, and you cannot buy anything else for the same price or cheaper that has the same or better features.



The bolt is proprietary but you can either buy a spare or hold to KAC's 20k round guarantee of replacement.

Knight's SR15 is arguably the equal of any AR currently made. Quality and performance is top-notch and their understanding of the rifle as a system is un-matched in the industry. It is, afterall, where Eugene Stoner worked for several years before he died. They are not cheap, but I personally know several people who own the SR15; none of them are rich and all of them adore their rifles. I would recommend feeling one up in person if you can...the quality is obvious. Shooting one makes you look like a better shooter than you are. ;)

I really love mine as well. My only regret is it wasn't my first AR. I really could've saved myself quite a bit of money over the years had I bought it first. Especially nice if you're a southpaw too.

Top notch and nothing better in a DI gun. I can't wait until the Magpul SR-15 E3 is released. Anxiously awaiting.

I agree with the comments above. No squabbles whatsoever with this rifle and it has all the inherent accuracy I will ever need. I had a minor CS issue at the start and Knight's took care of it right away. Highly recommended.

I wrote an article for SWAT on a pre-production model awhile back.

I was impressed with the rifle on many levels. My main caveat is simply one of distrust and I would want a spare bolt in my possession. FWIW, the proprietary parts I'm aware of are the gas tube, barrel extension, bolt, and trigger. These could be problematic, but on the flipside one could easily change out the barrel and bolt for standard parts (and same thing for the trigger as an assembly) in a pinch or in some dire circumstance if needed.

One of the most surprising, and impressive, elements of the rifle was it's relative weight when the list of features and specs is taken into account.

Perfect timing on this thread. I fondled one of these just yesterday and the first thing I noticed was the weight. Very god wieght for what it has for sure. Also found it was well balanced, pointed well, and just "felt" good.

What is the extractor life on an SR-15? Same as any other AR? I know it is a ball park figure. I would have an extra complete bolt for mine as well if for nothing else than piece of mind. Or at minimum the "field repair kit". For those that know can you buy a spare gas tube?

Good point, thanks for reminding me. I'd want a spare extractor and springs too.

Wes @ MSTN will sell the E3 complete bolt (it uses a standard BCG). The price is 350 bucks. That said after 10,000 rounds down my SR-15 E3 IWS it's never had an issue. Just saying.

Titleist have you gone 10k on the original extractor? The extractor is claimed and I am sure no doubt to be "improved". But is it function+durability? Or just function? I have not found a thread or an article that talks of extractor life and durability.

Extractor should do 20k no problem (and springs).

We do sell spare bolt parts now, however we put a lot of rounds thru these (and the SR-16's) and several others (Chris Costa, Travis Haley etc) have TONS of round thru them, and we are pretty sure ;) of the 20k life span.

I've been waiting over a month for a fully paid for order that is available at the manufacturer, and they continually lie to me about how it's not available.

I'll never deal with Knesek again.

And back on topic: I just picked up an SR-16, but haven't had a chance to shoot it yet. Love the ambi mag safety (I'm a southpaw), even beats the KAC ambi safety I put on one of my other rifles. Very light as well.

can anyone explain what the rounded bolt lugs and barrel extension design do?

GAST
04-23-10, 12:34
I can't say what KAC's reasons were for it, but in general machining practice wherever you have a sharp fillet radius (in this case, the bottom of the bolt lug) it creates a stress riser. With KAC using a large, rounded fillet and edge break on their E3 design it'll give the bolt more strength at those points on the face. I think a smart design improvement. Gene Stoner did have a hand in these if I'm not mistaken. :)

Belmont31R
04-23-10, 14:28
Exactly. The E3 bolt is designed to strengthen the bolt above that of a normal bolt. Also the cam pin area is thicker. They have strengthened the two biggest weak points on a normal bolt....the lugs, and the cam pin hole.

I figured I would post on this thread rather than creating a whole new one. Just got a SR-15 yesterday, and when I took it apart to clean it for the first time I noticed a splotchy looking area on one of the inside walls of the receiver. It sort of looked like stains, with darker and lighter colored areas. Never seen this on any other AR, is this normal? Does anyone know what I'm talking about, or should I post a picture?

With the rounded cutouts in the barrel extension, will a standard bolt still work or does it have to be used with the KAC bolt?

My 11.5'' SR-15 E3 + QDSS-NT4 Suppressor runs like a ****in' champ.

Accurate too, out of an 11.5'' barrel I can make critical shots at 500 yards.

I like that. I like that a lot.

Hey, If I swapped out for a Noveske barrel with a switch block - -

A - Would it fit under the URX II being so thick and all?

B - Would the switchblock fit?

C - Would the barrel extension be an issue?

Are you saying that you own an 11.5" E3 SBR with an E3 barrel extension and an E3 bolt? If so, a lot of folks around here would envy you.

A- a noveske bbl will fit under a urx, either the SS or the n4 profiles will fit. However, I don't think that noveske makes an 11.5 barrel, unless they did a special run. I think your options are a 10.5" n4 or a 12.5" ss barrel.

B- switchblock will not fit under the urx

C- what do you mean by "issue"? A noveske bbl will require a standard AR bolt.

The SR-25s aren't cheap. Why the huge price difference between the 5.56 and 7.62 rifles?

KevinB
04-26-10, 12:18
Building 5.56mm and building 7.62mm guns are not the same.

The amount of effort and precision that needs to go into building parts for a 7.62mm gun is more than 2x of the 5.56mm little brother.

As a result the cost gets passed down to the comsumer, we would have closed our doors if we sold 7.62mm guns at the 5.56mm price.

I don't think dear gov would be too happy if KAC sold 7.62 rifles cheaper than they were getting them for, and as such as things are most 7.62 guns KAC is making go to dear gov for a nice sum.


So no you will not be seeing any reasonably priced 7.62 guns from KAC so long as dear gov is their primary market.

mtdawg169
04-26-10, 15:19
I Would love to know if EMCs were seeing any use in-theater. While KAC has been very good to us civvies lately, I can't imagine that they could sell enough 7.62 guns to the civi market to be worth their investment.
