I’ve NEVER heard ANY other person talk about the amount of engineering that’s gone into the gas system and I’ve watched a bunch of videos on this rifle. Just another reason that makes me want this rifle even more. I learned a lot of knew information I hadn’t learned anywhere else thanks solely to your video. Awesome content and in depth video. Thanks for making the video and dropping the knowledge on us.
And people say you need a piston system to make the AR reliable. Imo it's just an elaborate way to make the gun heavier, recoil harder and more expensive to make.
You got a good thing going on this channel. Your tastes mirror mine almost exactly, and far moreso than any other channel I've seen. I'm confident this is a worthwhile endeavor for you and will pay off at some point.
@@gunsnmammons Whatever your motivation may be, it works out all the same to me: I get to watch cool videos on guns I'm actually interested in. I certainly do hope you continue full steam and make as many videos as possible.
I have the 16inch Mod 2 and I scored a 14.5 SR-16 E3 upper. Have yet to fire either one of them but like you said in the video, I 100% understand why they are the price they are. This is not your standard, run of the mill, AR-15. This is something different. Thanks for the video as well. Good info! Brett
Noice. What buffer system are you running with the Law folder? Standard H2 that comes with the CQB? I have mine backordered and plan on using a Law folder as well.
Unfortunately the reality with KAC is the enthusiasts want them but the guys using them for work get a degree of priority. That being said when they are available you have to move quickly. The mod2 14.5 is a heck of a rifle
@@gunsnmammons oh for sure. Same thing with lmt rn. Their new zeland and eastonia contracts take priority and they just switched facilities. Good news is that I was able to track down a 16” rifle but kinda on the fence. Think I may just hold out for the 14.5 upper I really want rather than break the bank on a 16” rifle
I dig this setup a lot, especially the optic setup, are your buis standard height overbore as say an a2 front post. And does the magnifier mount get in the way of seeing your buis through the window? Thinking about doing a mk18 mod 0 clone and using the high rise mount, aimpoint t2, g43 magnifier, a2 front post, lmt fixed rear sight. Not sure if they would all work in harmony. Feedback is appreciated
You definitely would be able to use the irons with the skyscraper and that setup. But that being said with a clone you could go different routes with risers such as LaRue. But the skyscraper would work with your build.
It is slightly less than a standard DI ar15. I’ve learned a trick to reduce gas to the face and it is some silicon on the charging handle to better seal between the upper. Works really well
I currently have a 16”. Obviously since the barrel is longer it shoots smooth. Do you think it’s a huge change going from a 16” to a 11” CQB? Or should I go for a 14.5”? Just want a shorter barrel I think.
If you want a do it all go 14.5. If you want a good carbine that is decently compact with a suppressor go 11.5. For 16” and above I would assume it to a SPR/recce role
Couple of questions if you don't mind: Does the handguard have any anti-rotation features build in? Also, total weight of the rifle as seen in the video?
Honestly I am not well versed in the design of the URX 4. I do know that it threads on the receiver threads and the gas tube goes through it somehow. I am not sure about anti rotation features though. And on the note of weight it is most likely around 10 lbs or so. I am not exactly sure I am sorry..
@@gunsnmammons No worries man. Thanks for taking the time to reply. Love the suppressor test-to-failure vids! You’re truly contributing something new to the community
Great video! I’m new to this as I got my firearm license last week. Would you mind letting me know (or send links) what optics you have on your ar15? One of them is EOTECH magnifier G33 but I can’t find the other one. Thank you, Bart
Thanks man. The optic itself is an Aimpoint T1 4MOA red dot. The optic is sitting on a Knights Armament Skyscraper mount. The G33 magnifier is sitting on the back railed portion of the skyscraper.
Why the optic riser + cheek riser. Couldn’t you just use neither to the same effect? Also can you pull the charging handle all the way back with that cheek riser? Not trying to be a dick it’s an awesome build. Genuine questions.
I would try to explain it but Mark Smith does it much more eloquently. Check out JBS Training Group on RUclips. Basically the riser is for a heads up position and the cheek riser provides a cheek weld versus a chin weld. The elevated optic gives the heads up stance which is more comfortable imo. It is a user preference thing that you really cant put into words unless you shoot it. I get this question a lot because it does seem counterintuitive.
Hey I’m thinking in getting a kac but I’m stuck between a 14.5 or 11.5. Mostly towards a 11.5 but at that point I’m not taking advantage of the gas length kac is known for so I wanna ask how smooth is the 11.5 is it gassy?
It’s not terribly gassy, the MOD2 system overall is very well tuned. But if you’re looking for a smooth shooter, the 14.5” is awesome. I went with the CQB because I wanted a more compact rifle.
Haha i didn’t mean to advertise my gloves but yes. I really love them. Pretty comfy and allow for quite a bit of dexterity. They’ve held up pretty well against hard use
Absolutely. I would not advise to use the CTN warcomp for a suppressor host. Works great as a stand alone. I will likely go back to a 4 or 3 prong flash hider. This thing gets stuck so bad
@@gunsnmammons I have the Scalarworks 1.57 LEAP on my 11.5 and it’s a high quality Mount. The fact that it only needs to be hand tight and it locks itself in is amazing.
@@samculpepper7289 The Unity is 2”. ScalarWorks makes several LEAP mounts in different heights. 1.42, 1.57 and 1.93. I’m running a Primary Arms 1x Cyclops on my 11.5. So I decided to go with the Scalarworks LEAP 1.57 and I love the height of it. I wanted a bomb proof SHTF optic that could run regardless of battery’s and the Primary Arms 1x Cyclops is basically a budget friendly ACOG but with a WAY better reticle (ACSS) with almost the same built like a tank properties. There are some wild ass torture tests on RUclips. One where a guy takes a PA 1x Cyclops Gen 1 and lights it of fire. Smacks it with a bat a bunch. Leaves it in his pool over night several times.

@@gunsnmammons there's no point in a 1.93" (which it looks to be) red dot riser if you're just gonna throw a riser on the stock too. Defeats the purpose. Might as well just go with an absolute or 1/3 cowitness mount. The iron sights are kind of sketch to me, the one in the front is on backwards to save rail space and is just kind of.... out there, when folded down. Looks like it would interfere with a suppressor being mounted, or even be prone to breaking off after a hard impact. The rear irons are equally wonky, it appears that you wouldn't be able to flip it up without first folding the magnifier to the side, and i simply dislike that. I don't think those iron sights are even visible through that optic because of the height of the mount. Other than that just simple stuff, like moving the grip stop up a little ways
@@gunsnmammons also how you gonna drop 2.5k on a rifle, then another grand and a half on accessories and still run an A2 grip lol No hate tho, love the video
Haha i appreciate the feedback. I get a lot of negative feedback on my riser and RISR. The reason for it is just shooting position, it’s something that you have to be on the gun to really feel. The iron sights I promise will not break, and they don’t interfere with the suppressor.
It goes against our self-interest as civilians to be propping up and cosigning for companies that treat us as "Garbage Tier consumers." Companies like H&K, and Knights Armament cater heavily to government contracts and occasionally give us the left over scraps. Often times the leftovers we get are manufacturer blems or contract overruns..... We don't have to give our business to these companies, and we shouldn't. Glock, Sig, Geissele, FN, Aimpoint, and Eotech are some of several companies That make sure the civilian market is well taken care of, despite catering to well-funded government contracts. These companies are the example of what is expected of companies we choose to support with our money.
Knights is definitely expensive but I would say to the end user looking for innovative features that push the line of the platform the cost is justifiable. But I am also satisfied with my BCM rifles.

Yes sir it is the standard buffer that comes with it. So far no complaints from unsuppressed and suppressed firing
Lol I wish they’d produce a lot of them. I want a 14.5 or 16” upper so bad

Another nice collection and great review. Keep these coming as long as your wallet allows 😀
Ain’t that the truth 🥴 thanks!

Great video! Quick question, does the KAC SR-15 CQB use a 6 position or 4 position receiver extension? Thanks
6 position if I am not mistaken
Is the shoulder past the hand guard? Would a surefire suppressor and muzzle device have enough room?
I run a surefire suppressor on this rifle, it is close but it fits.
Did u change anything in the buffer assembly when u added the law folder? Or is it all OEM knights parts
The buffer and spring are still the same. The Law folder comes with a little plug that basically acts as a spacer between the bcg and the buffer

Did the rifle/upper come with that muzzle device and did it come with a pin and welded muzzle device?
No, this is an 11.5" upper, so no sense in p/w. This came with a QDC style 3 prong flash hider.
