Knights Armament

I really like KAC lowers and the uppers are fine except they are not as accurate as some of the aftermarket barrels. Even the LPR is only fair. All of my AR stuff started out as KAC.

Really? My LPR shoots so well that I'm awestruck half of the damn time. It's like when you ride a rollercoaster and literally can't stop from smiling awestruck.
 
Great. You have the best of all worlds.

I have never had a bad one. All were from 1 MOA to 2 MOA. That is over about 20 or so rifles. The 5.56 rifles were on the most accurate of course. None of my large frames would beat 1.5 MOA. This for average of 5 10 shot groups.

Some of the better aftermarket barrels will cut that in half.

I've heard of some KAC rifles that weren't shooters (never seen one), but everyone puts out some duds. I've had no less than a dozen KAC rifles and they were all shooters. Only a couple SR25's but they were both 3/4moa or better rifles with FGMM. I've had numerous SR15's, one MOD 1 I had with the regular 16" CL barrel would routinely shoot in the .3's with cheap federal american eagle 50gr varmint ammo that cost like $.30/rd.

LPR's come with Krieger cut rifled hand lapped barrels which are among the best barrels that money can buy. I had two LP Mod 1's and they were both 1/2moa guns. One started shooting like shit around the 500 rounds mark and it went back to KAC and that's when I learned that they had gotten a bad batch of barrels from Krieger, there were several other accounts of people having the same thing happen around the same time. KAC replaced the barrel and the new barrel shot 1/2moa again.

Most of the KAC accuracy complaints stem around their can that mounts back on the barrel. It's a shit design and unless you get a batch of rifles and cans and swap them around to see which one works best on which rifle then chances are you're going to have less than stellar results.
 
I had 5 or 6 LPR's. They form the basis of my present rifles. I simply changed the barrels, gas blocks, bolts of course and went to JP captured buffers.
The Kreiger barrels shot slow and only fair for accuracy. I now use Proof barrels, or Douglas Mk 12 barrels as set up by Alan Brown from Crane.
YMMV.

Are you referring to the reflex cans (Mk11 mod 0 and M110)? If so, were the complaints you reference pertaining to loss of repeatable precision or POI shift vs unsuppressed? If both, wonder if the can didn’t fit tight onto the attachment points for those rifles in question...

IIRC, KAC would have to try different M110 cans on each M110 rifle before issuance to keep within the POI requirements the Army/USMC specified in those respective contracts as different cans had varying measured POI shift on the same rifle.

I haven’t heard the M110 or Mk11 mod 0 cans made the gun less precise and hasn’t been my experience with my Mk11 mod 0 suppressor on my SR25 or Mk13.
 
There's a reason the mil went away with the kac m110s. Go HK.
 
Is the KAC 2 stage trigger worth the extra money? Or the Super Semi-Automatic Enhanced (SSA-E) Trigger? Or others for SR16?

Definitely the Geissele.
The stock trigger in my SR-15 is nice enough that I wouldn’t replace it with a Geissele, but if I’m buying a trigger, I would absolutely go with the SSA-E.

I guess I’m the only one who prefers the KAC 2 stage trigger over the geissele. The Geissele has too much travel on the first stage. The KAC first stage is super short and has good feedback for fast splits.

My KACs are the only rifles I have not swapped out with Larues. I really like them too and using them keeps my form solid when using the lighter pulling Larue. Kind of like when I was using an M16 with milspec trigger for a living I was very proficient with it-then the first time I pulled a Geissele it was like butter. Well you need one to feel the other.
 
I guess its what you get use too. Delta operators always told us you had to know your trigger. How much play/travel in trigger and execute shot on target. Your sight/barrel only stays on target for a split second execute shots on to next threat.

The stock KAC triggers are very good, but for a precision rifle, I like something a little better so I've changed the one on my LPR to a Geiselle, the others are stock & will remain so.

Recent 5 shot group with some Magtech 77gr OTM ammo I just got in-LPR

Atlas bipod and rear bag on concrete bench-

This is good shooting for me-because for all this "1/2 moa all day" talk requires not only a gun but a shooter capable of that-which is rare.

Bone stock LPR.

The mod 2 gas system also. The LMT comes close but you trade into a barrel that isn’t hammered, has a drilled pin, short gas system and weighs more.
LMTs are all on the heavy side no doubt. The New Zealand Ref rifle has a mid-length gas system and is a pretty smooth shooter but not KAC smooth. As far as LMT barrels-I have 308 ss, 308 cl, 6.5cm ss, and 556 cl-all shooters. My 6.5cm and 308 ss are sub moa and the 556 is new but looks very promising. I have not spent a lot of time with my 308 cl so no data there. That being said my KAC LPR with Krieger barrel shoots laser beams.
I agree with all of this. I just got a New Zealand ref rifle and it's actually a pretty smooth shooter-which I attribute to the weight and mid-length gas system. Not KAC smooth though o_O
I have an 11.5 SR16, love it. Paid about 1425 I think for it, maybe 13 something I can't exactly recall.
The URX3.1 is probably one of the best rails ever made imo, and the URX4 on the SR15's is also excellent.
The SR16 has the MOD 1 gas system, as opposed to the newer MOD2 on the SR15s. Still very soft shooting, much more so than my .070 ported 10.3 MK18. But I would say that the SR15 MOD2 is still the superior upper because of the MOD2 gas system.

The E3 bolt is realistically not a problem imo, as it will likely never break even on heavy auto firing schedules (I have never heard of an E3 bolt breaking, neither has any of my KAC owning friends, but obviously it hypothetically could after an absurd amount of rounds). Rebarreling can be done at any certified KAC armorer last time I checked, but even so, if you are a person who feels the need to do everything yourself that proprietary design may be an issue for you. If you get the Sandcutter carrier it is designed with channels to help break up and shift away dust, but the LMT carrier (as well as any other carrier) also works.

We can get into the discussion of whether "if you pay KAC prices, you can afford a new barrel", etc is true, but everyone will have their own opinion and situation regarding that.

KAC in my experience also has great customer service, their reps that are on FB and ARFCOM and have always been helpful and knowledgeable, and they have a record of improvement and development of new tech that is attractive to me.

The Mod2 gas system on my LPR makes it a really nice and soft shooter. I have an LMT MRP rifle and find it to be too heavy and not up to my KAC LPR goodness. The new KAC Mod2 SR-15's may not get a lot of good press coverage but, they are a top choice for a premium AR-15 style rifle.
 
Honestly, most will never put the KAC, LMT or BCM through the ringer. If you want a SR-15 go for it and enjoy it, same goes for the others I mentioned. I have use Stag, BCM, Robinson XCR and POF 415 for classes and none of them let me down. Shit the one that dealt best with manufactured jams was the XCR, couldn’t jam the Mfer for shit. That said for SHTF I’ll grab my BCMs all day long. Just pick a good rifle and shoot the fuck out of it .
 
Show me a broken Sr15 bolt and then you can complain about proprietary. Also, do you realize that you can run a non-sr15 bolt in an emergency situation?

Oh i'm not complaining at all as they are good rifles .. just saying if it hits the fan I want options that are more universal

from my understanding direct from KAC you can't reliability run a non KAC bolt as its risky.. unless it's changed from their original versions
 
Kac overrated. BCM will do everything KAC will do. Its definitely the Harley mentality to try to be part of a club.
they are not overrated at all.. BCM make good stuff also but make no mistake that KAC is not overrated

BCM is barely above PSA. Paul Buffoni relies on Celebrity endorsers and Grant Timberlake’s forum. What has BCM done to earn the top tier status? Where have they been proven? “Cause XXXX said so” and “you’ll get banned for bad mouthing the forum sponsor” doesn’t really prove much.
 
LOL BCM isn’t shit, but it is not on the same level as KAC.

There’s people that will swear their $300 Anderson build is as good as KAC too though, so I guess it could be worse. Still have to feel sorry for the sad folk that can’t see the difference.

I put a Geissele hi-speed in my SR25 because I wanted it a certain way but the factory KAC trigger is on par with the SSA (and maybe the SSA-E) IMO.

I put the KAC trigger back in another KAC lower though to use in another high end rifle... Had the rifle not been the 20" version and more of a battle rifle I'd probably have just left it.
 
Thanks for all the info/replies. Seen some Sr-15 Model ones for sale but model 2 is current. Does it matter?
 
I wouldn't turn down a SR-15 if someone gave me one but when I can assemble 2 quality rifles for the same price of 1 SR-15.....
