SR15 BEAR

Very impressive. How does she run?

Ever drive a Ferrari?

Should've just got an E3 upper.

I shouldn't have anything. My money my life. If you don't like it that's fine but don't come in here telling me what I should and shouldn't do. I'm very happy with this rifle and if you don't like it you can shove it.

Jesus calm down, all you have is an SR15 lower with a triple tap and you post it in the KAC industy forum? What do you expect? There is a reason KAC went with a DI gas system over a gas piston design. I doubt you'll find a ton of love for a gas piston AR on AR15.com in general let alone here. You obviously spent a ton of money on your rifle and if you like it great, but it is what it is. Better place to 'leave your pictures" than here though.

You've got some red crap in your lower.

Pretty much. It's nice and has every tactical whiz bang accessory of the month on it. However, there's no need for the attitude.

Constructive criticism is fine I can take that. However coming here saying the work I've done and the idea I have sucks isn't. The fact that the ADCOR manual says clean every 1000 rounds has to tell you something about this system. It doesn't "suck" and neither does gas piston. Sorry if I don't subscribe to your line of thinking.

Also if it has every tacticool gadget on it where is my vertical foregrip or afg? I do agree making a whole topic for it was pretty stupid but at the time I was giddy as a school girl because I had just finished it.

When one comes in telling me what "I should have done" I consider that to be hostile and while I could have responded differently I blew up.

Good luck finding spare parts for your upper in 10-20 years.

Very nice looking setup, I like it! Congrats!

ARKAR

Here to interject yet again. Your dead wrong. A little research on ADCOR would prove this. ACDOR is responsible for 80% of the can and bottle filling capacity in North America. On top of that they make (if I remember correctly) 25 critical parts for the Navy's and Air Force's missiles systems. On top of that they also make tools for NASA as well. Now they have also brought. Now they have entered the small arms market as well.

Sorry to burst your bubble but I don't think ADCOR is going anywhere. I would love to see KAC and ADCOR offer a rifle based off this platform I think it would be a real good step forward in the AR evolution.

Too bad there is no real problem with direct impingement systems.

Ill tell you what you should have got, should have got an E3 upper.

Im very happy telling you this.

Agreed. IMHO, he ruined a perfectly good KAC lower.

Again, you're going to be fucked for spare parts one day.

If companies like Robinson Arms and Bushmaster can't/won't support legacy systems, I wouldn't expect a firearms upstart like ADCOR to either. Don't worry, you'll be in the same boat as a lot of others with piston uppers though.

This

I give up with you guys. There is obviously no reasoning with you. It's either your way or the highway it seems.

Heh –– I know we come off as a bunch of douches. :^) Let me try to explain what I see wrong with this rifle. This is in no way authoritative –– just some internet jerk's opinion:

One of the many reasons I like KAC rifles is that they have real AR-15 DNA in their design –– KAC was Eugene Stoner's last employer to my knowledge and part of this lineage is a belief in the reliability of the direct gas/internal piston system. Then there is my belief –– that isn't related to KAC –– that external piston uppers are solutions looking for a problem, etc (the age old debate).

So it seems incongruous to put a, in my opinion, useless piston upper on a Stoner Rifle lower.

Then, like your other, >$5000 build, I think this one suffers from too many "improvements" like the gapper, external piston upper, spikes buffer, triple tap brake, Geissele trigger, etc. that don't seem influenced by experience.

Still, I'd be interested to know why you purchased a brand new KAC lower and immediately swapped out the sweet KAC two stage trigger? Was this a decision informed by actual shooting? Why did you get a $500 muzzle device? Are you planning to get a KAC suppressor?

Why did you color in the roll marks and other logos?

Thank you this is the way I wish people would have come in here like earlier.

To address your questions in order;

I did try out the KAC trigger. While good I like GA triggers it's a personal preference on my part. I feel the break is much more smoother.

Secondly yes. I do plan on getting this cut down to an SBR and running an NT4. Also while I was at the range I have to say it was ridiculously fast and controllable.

I wanted to doll it up and make it look nice and put my own personal touch on it.

Regardless of what you think of how this guy spends his money, he certainly had enough KAC to post here. Hell, there are people who posted in the KAC pic thread with just a vert grip and they didn't catch this kind of hell. That lower is suhweet and I hope to get one someday to mate with my SR15 upper.

Edit: red

Cool –– well, ultimately I think a fair amount of the goodness that comes with an SR-15 is its enhanced DI system in the upper. I also think we're a more practical bunch who care more about how our gear functions than appearances. I think our aesthetic puts more weight to elegant and functional designs and not colored roll marks or accuwedges.

You guys need to lighten up, it's a nice build, he spent a lot of time and money on it and I say " to each his own ". Remember this is America .

The biggest reason why I chose to run the SR15 lower was that it is fully ambidextrous. As a lefty that is a big thing for me. The forward charging handle can be move to the left side for right handed users and I'll tell you what it makes a difference imho. If you would want to compare this rifle to anything your best bet would be an ACR. I do go for function just as much as I go for looks. If I had gotten a traditional lower I still would have had to put all the ambidextrous controls on regardless. This would have included a BAD lever. I wanted to try to keep this as sleek as possible so when I saw the SR15 lower I jumped on that like white on rice. If you really don't like this rifle then come down to Florida get in contact with me and let me change your mind. I'll take you to the range with a boat load of ammo. I guarantee you will be singing a different tune once you do.

Consider this. the HK416 or MR556 weighs practically the same as this rifle bone stock. If you look at everything I've done to this I think you can come to the conclusion that this rifle is far superior.

I like my stuff to look just as good as it runs. I think it shows that I care about my stuff and maintain it. On top of that I like my rifle to be tight so that's the only reason the "accu wedge" is in there in the first place. I don't buy into that accuracy is better with it bull shit.

Also this isn't a combat rifle and it isn't issued to me and since it's my own money well you can put two and two together.

We all have different philosophies and opinions. I think piston is better. That's me. If you don't I can understand but as others have said there is no reason to come on here and give me shit about it.

Here's what I would like. What do you think of this rifle based on it's merits, concept and execution?

I'm in N.FL and I may take you up on that offer. I'm a lefty also and the KAC lower definitely is my ultimate favorite..

I think it looks awesome
Does it have an ambidextrous charging handle in the normal area?

No. I haven't been able to find anything that I think beats out the gunfighter mod 4. If I do need to use the rear charging handle (which I don't) I tilt the rifle to the left, bring my support hand around and charge it with my support hand.

Does the op rod dove tail into the carrier or is it only attached with screws? I really like the forward charging handle/s, and how it still retains the legacy CH position.

Everything you need to know about the whole system is broken down here.

Very cool.

Very cool indeed.

That does seem pretty slick. Hopefully they will offer an SBR upper, I'd shoot the hell out of it suppressed.

Okay, I'll eat crow here. That IS pretty slick, I'm still not in the market for a gas piston AR, but thats a much better design than most I've seen out there. Still not a fan of the red and white paint though just razzin ya now.

That does look pretty slick. The charging handle design is pretty neat. Still doesn't add any legitimacy to the argument for a piston upper though.

What holds the ADCOR's lower handguard on? It looked like it just snapped into place. I hope there's something substantial retaining it. Maybe he just had it lightly attached for demonstration?

Sure it does. It's cleaner, runs longer between cleanings, doesn't burn off its lube, and much easier to clean. That's all the legitimacy you should need right there.



There is a detent which had a metal band that wraps around inside the hand guard to apply pressure. No springs.

How many rounds have you put through it so far? How are the groups?

Not much I took it to the range briefly to break it in. Probably around 80 rounds or so. I was zeroing it in but the weather turned sour real quick so I packed up. I'm going to take it out again this Saturday and hopefully the weather holds so I can zero it and start pushing it.

I need to zero in the optic still along with the laser.

Are you going to the 200m open range at Hernando on Saturday? I'll be there with a SR-15 and my SR-25's. If so, I'll check it out. Since you have a triple tap, I can bring my NT4 suppressor for you to shoot. Be neat to see how clean it stays with the suppressor on it.

Yep I should be there. Along with my brother with his new RPK and my dad with his LWRC.

Nothing wrong with trying out a new concept. Nothing wrong about that Triple Tap either - Hells Yeah! And, really, although there has been much arguing about this build, I think it is one million times better than the first one you built. So you are improving, grasshopper. Get your light setup more functional with a Surefire XT07 switch and a VFG and you'll really be getting somewhere. The VFG will help you drive this weapon to the target. I also agree that a lot of people have been pretty hard on you about these builds. As long as you learn something from them, then hopefully you'll come out better on the other end.

If I were you, I'd sell rifle #1 and buy 1.) Ammo 2.) A KAC Suppressor, and 3.) The KAC 11.5" "block three" SBR with URX and the SR-15 IWS when it comes out. Wouldn't that be somethin!
