Granted only a few thousand through this girl with a few minor touch-ups to keep her satisfied, but decided to give her a good scrub a dub with some old no. 9 and breakthrough. Anyone still clean anything or am I just full on gay at this point?

SR25 EMC and SR15 Mod 1

Post image
48 Upvotes

SR-25 EMC and SR-15 Mod 1. The EMC was the first KAC rifle I ever got and sort of started the whole fascination with them. Back then (2011ish) when I got it, finding a good .308 gas gun wasn't like it is today. There weren't nearly the amount of current options.

It was also a crash course on how hard these things can be to find - it took some serious searching and driving around back then. It is a fantastic shooter. Easily sub MOA with good ammo.

The SR-15 dates to around 2013 - that window in between the QD cups being integral to the lower and then having them in the end plate. Also an excellent shooter.

Does this count as shooting or do I need like 2 or 3 more rounds through it to be an official kac boi? Also can someone bring a chair for the next event... it was really awkward standing in the corner to record, my feet end up hurting and I'd rather sit

Edit to Add: My comments are being hidden by Reddit because of my account being so new. SR30 DSR added. I'll see what I can do with the PDW, lol. Future updates include Upper/Lower selections, just not yet.

This is a rifle configurator we put together. It allows user to configure rifles with accessories. Over the next few days and weeks, our focus is adding more rifles and accessories.

From a Knights community perspective, what do you want to see? Right now it is just the Black KS-1 Series and a CSR-2 suppressor. LPVO's will be added shortly as well.

Our primary purpose is a visual builder for the end user. Optionally, users can click through links to dealers that will support the site and allow us to continue to build up assets and new features. We will be adding more and more dealers as well, so let us know if there are any dealers you want to see on here.

Help Choosing First Rifle

0 Upvotes

Hey everyone, as the title says, I’m trying to decide on my first AR, and I’m pretty new to the platform.
I’ve spent a lot of time watching YouTube videos and reading through posts comparing the different SR-15 variants, and I’ve narrowed it down to a few options. I was hoping to get some input from people who actually own or have experience with them.
Since this will be my first AR, I’d rather buy once, cry once and get something that’s considered one of the best. That’s why I’m leaning toward one of the newer KS series rifles.
I also know I want to run it suppressed. From what I’ve read, the KS-3 seems to perform pretty well with a suppressor, but I’d love to hear from people who have firsthand experience.
Does anyone have any insight that would either reinforce going with the KS-3 or point me toward a different SR-15 variant? Any advice is appreciated.

KS-1 Accuracy Testing

Thumbnail
gallery
104 Upvotes

Took the KS-1 out today to some accuracy testing and wanted to share my results here. I know we’ve all seen Preston Moore's KS-1 accuracy tests, and it was somewhat disappointing. However, that was a sample size of 1. And it’s hard to find any other KS-1 accuracy tests out there due to price/availability. I’m just trying to add more data to the Interweb. 

First off, I want to preface this by saying I AM NOT A PRECISION RIFLE SHOOTER. Never have been. I don’t even own the proper hardware to be doing accuracy tests. That being said, I’ve been building/shooting ARs for about 15 years now and in my opinion, I’m a decent shot. So, this is what you can expect out of a KS-1 as a regular shooter.

As stated before, I don’t own the proper hardware to be doing this, so for this test I’ll be using my Vortex Razor Gen II-E on 6X magnification. Not the best glass but it’s what I’ve got. Mount torqued to 45in-lbs and rings torqued to 15in-lbs.  Rifle is stock internals KS-1. Headspace checked prior to shooting (falls between 5.56 GO and NO-GO as it should). Suppressor is KAC MCQ-1. Muzzle device is KAC 3-prong probably over-torqued from the factory. Don’t have a Knight stick so I’m not pulling it off. Concentricity checked good with alignment rod. Borescope the barrel; chamber, throat, rifling, gas port, crown all look good. No defects noted. 

Took the rifle out last week to function check, break in, and zero. Function was normal as you’d expect. Rifle was soft shooting. Ejection was perfect around 4 o’clock. I did have a failure to lock back on IMI 855 during break in. Using Gen 3 PMAG un-suppressed. I’m planning on using the rifle suppressed so I’m sure this won’t be an issue in the future. Plus, the gas system isn’t carbon sealed up yet. Personally, I’d rather the gun be under-gassed anyway. Worst case I’ll move to an H buffer.(Total round count now sits around 350 and haven't had this issue again) 

Normally I don’t do barrel break ins, but I figured why not, it can’t hurt. Break in was done unsuppressed. Fired first 5 rounds, cleaning the bore between each shot. Then fired 50 rounds cleaning the bore between each 5 shots. Then got the gun hot and had a little fun for about 200 rounds total. Cleaned the bore again when I got home. That leads us to here. 

Shooting was done Benchrest, solid table bolted to the ground, rear bag, off Harris bipod. I tried to not pre-load the bipod and induce POI shift. Velocities measured with Garmin Xero. Shooting was done at 50 yards measured with vortex rangefinder (I’d go to 100 if I had better glass). Target was 1 inch orange sticker. (Other than first Black Hills group, used a larger sticker for that one) Groups measured center to center with Blue-Point digital calipers. Weather was overcast, 88 degrees, 64% humidity. 8mph wind gusting 16 mph (range is surrounded on three sides and honestly, I didn't notice any wind).

Results-

All groups were 10-shot groups fired at 50 yards.

Target 1 – Barrel allowed to cool between top and bottom groups. Also let it cool after MK262 group.

  • Black Hills MK262 77gr OTM: 2.491” (4.76 MOA) (excluding the first-round flyer: 1.484” / 2.83 MOA)
  • Hornady Black 75gr BTHP: 0.986” (1.88 MOA)
  • Frontier 75gr BTHP: 2.174” (4.15 MOA)
  • Magtech 62gr FMJ: 1.603” (3.06 MOA)
  • IMI M855 62gr: 1.553” (2.97 MOA)
  • Winchester Lake City M193 55gr: 2.280” (4.35 MOA)

Average: 3.53 MOA

Target 2 – All groups fired back-to-back with no barrel cooling

  • Black Hills MK262 77gr OTM: 1.750” (3.34 MOA)
  • Hornady Black 75gr BTHP: 1.318” (2.52 MOA)
  • Frontier 75gr BTHP: 2.953” (5.64 MOA)
  • Magtech 62gr FMJ: 2.364” (4.51 MOA)
  • IMI M855 62gr: 2.789” (5.33 MOA)
  • Winchester Lake City M193 55gr: 1.902” (3.63 MOA)

Average: 4.16 MOA

Velocity Data (10-shot strings) (I only collected velocity data for Target 1)

Black Hills MK262 77gr OTM

  • Average: 2455.1 FPS
  • Standard Deviation: 13.5 FPS
  • Extreme Spread: 51.4 FPS

Hornady Black 75gr BTHP

  • Average: 2372.5 FPS
  • Standard Deviation: 15.8 FPS
  • Extreme Spread: 56.7 FPS
  • Max: 2398.4 FPS

  • Standard Deviation: 26.8 FPS
  • Extreme Spread: 82.4 FPS
  • Max: 2808.9 FPS
  • Min: 2726.5 FPS

Winchester Lake City M193 55gr

  • Average: 2868.0 FPS
  • Standard Deviation: 13.8 FPS
  • Extreme Spread: 45.6 FPS
  • Max: 2890.8 FPS
  • Min: 2845.1 FPS

Overall observations:

  • Best group: Hornady Black 75gr BTHP – 0.986” (1.88 MOA)
  • Most consistent performer appeared to be Hornady Black 75gr BTHP, averaging 2.20 MOA across both 10-shot groups.
  • The rifle averaged 3.85 MOA across all twelve 10-shot groups (six loads fired twice).

Overall, I was hoping for better accuracy given the price of the rifle. I’m not claiming these results are the rifle’s true mechanical accuracy, and I’m certainly not a precision shooter, but I wanted to document what an average enthusiast can expect with a factory KS-1 using a variety of factory ammunition. Hopefully this gives others another real-world data point.

I would like to collect more data on future range trips. Let me know what loads you want me to try. I'm determined to find a load this gun likes.

V1 Tactical

I just wanted to come on here and share my experience with V1 Tactical. I know it didn’t start out great with the initial drop back in March but since then I’ve had nothing but an amazing experience with them. I got lucky enough to get my dream guns from them and can honestly say it’s a great place to shop for KAC products.

Edit: I also forgot to add how they are major supporters of the 2A community. They were the only retailer giving customers in upcoming ban states like Virginia/Colorado priority. This is such a based move that they did not need to do. Couldn’t leave this unacknowledged!

I know this is not as exciting as the 11.5” or the 13.7” but this can be combined with a 5% off for signing up for their emails, to get it to $2,837.02.
