First shots with my KAC SR15 MOD2

AR/M4 AR General Discussion
1

Took out my SR15 MOD2 this weekend with my old man and some other guns. Contrary to what I am usually shooting this was a different kind of day. We had out our Benelli M4s, a Springfield TRP, HKVP9, G21 and the MOD2. Had an awesome time.

I set up my sr15 with a Aimpoint T2 with LaRue LT660 QD and put on a SureFire SFMB556K muzzle brake.

Recoil? Whats that??

I am completely blown away by how wonderful this rifle shoots. How smooth it cycles and how there is so little recoil its unfair. Also how comfortable it is. My other AR is a MR556A1 and while I love that rifle and its been flawless…its a pig.

Long story short I fired 400 flawless rounds on day one. They went so fast I thought I had only fired a couple mags. And Ive placed an order for another SR15. (Im a huge believer in 2 is 1 and 1 is none)

For an HK fanboy, KAC SR15 is definitely IMO the BEST DI AR out there and unless youre going to be diving with an AR… The SR15 is the better choice between it and the MR.

Very nice! I love that setup. Thanks for the review.

Thanks man!

Trying to decide what light I want on it and then shes done!

Nice way to spend the weekend. Wish I could still shoot with my old man. We had some great times… :slight_smile: Your KAC seems like a winner. Enjoy the hell out of it!!

Thanks for that honest review!

I was in the same boat and went with the HK MR556 myself. I got a barely used one for $2200 shipped with some HK mags and the bag. Already have a Geissele rail/trigger ordered and a Magpul CTR, enhanced trigger guard, regular takedown pins, K2+, and MBUS Pro sights swapped onto it. Now just waiting for the tax stamp to send it off to fat camp to be a 10.4" HK416 clone.

But your review rekindled my interest in owning a KAC SR15. I think I’ll wait for the MLOK railed versions to arrive before I decide. What made you decide on the 16" rifle length for both KAC?

What’s the Aimpoint T2 like?? And are you using the rail panels?

7

Aimpont T2 is very nice. Super lightweight and glass is very clear. The QD mount is what makes it so nice. And no grip panels

Thanks for sharing, and looks like you a great time. I love my Mod 2, and I went with a T-2 as well. The dot clarity is definitely noticeable over the two T-1’s I’ve had, for me anyway. I am getting tired of waiting on a 5.56 MAMS though.

Enjoy.

I think you’re giving the SR-15 more credit than is due. I have a Mod 2 upper as well, and while it’s a nice feeling system, it’s not noticeably nicer than my tuned BCM middy.

I think your “lack of recoil” experience can be more attributed to your muzzle brake than the intermediate gas system.

When I got my Mod 2 I put it on an A5 buffer system equipped lower and played with buffer weights and springs (milspec spring and springco green, A5H1-A5H3 buffers) till I found what kept the gun the flattest and softest. I then compared it side by side with my BCM middy gun that runs a springco green and A5H3. Both rifles have 16" barrels and both have Griffin Flash Comps on them. The difference between them was very slight such that you wouldn’t notice the difference unless you were specifically thinking about it. I can’t imagine the stock setup with milspec carbine spring and CAR buffer would be any better.

That said, I agree with you that it’s an excellent handling rifle (only my LW rifles handle better).

I find that the lack of recoil is directly attributed to the gas system. Mine has an A2 flash hider and it shoots like a dream

11

You’re missing half the rifle. The complete system is where the magic happens.

12

Same here. Mine shoots extremely soft. Only modification is the charging handle and I updated my rail to the URX4.

13

The gas system on the SR15 mod1/mod2 makes it an incredibly soft shooting rifle out of the box. Adding the surefire break and you have a rifle that virtually won’t move when being shot. My Mod 1 with a MAMS is amazing.

14

Not at all. I have had two SR-15s and tried a variety of brakes between the two, and it has been by far the smoothest and softest shooting rifle I’ve ever owned. I constantly am kicking myself for getting rid of them.

15

And what magic would that be? Short of some special RE/ buffer/spring combo (pretty sure it’s carbine buffer and spring), the lower does nothing for recoil characteristics.

16

An SR15 with an A5 stock kit and an efficient muzzle device is pretty amazing. Add weak .223 ammo and it’s like shooting an air rifle.

17

Any problems with running weak .223 in an SR-15 with A5 setup? I heard to stay away from weak ammo for SR-15’s, but at the same time this was from people that don’t have the A5 set up in their SR-15’s. Does the A5 add anymore reliability?

I know the SR-15 has a slightly elongated gas system, so I was unsure of how this would pair with the A5

18

I have put several mags of .223 through my SR-15A5 with no problem, but I haven’t tried every flavor of .223 in it, though. Definitely try a few boxes before you make a large bulk purchase of .223 if that’s your plan.

19

I shot some AE .223 through mine with no issues (worked with Springco Green and A5H3). I can try some MFS steel cased stuff next time I go out and post back.

I’ll also try throwing it on a lower with milspec carbine action spring and CAR buffer, but I’m still skeptical it’ll be any better than with the A5 setup and BCM middy + A5 combo…

20

I can’t comment on running weak 223 through my SR15, but I can say, I swapped the upper to one of my A5 equipped lowers and tried every A5 buffer weight and noticed no difference from the stock buffer and spring. This was with 855 62 grn ammo.
