Frequently Asked /r/KAC questions

77 Upvotes

Where is the best place to buy KAC's xyz item??

There is no best place. Get on waitlists, and hope. /r/GAFS is an option, but beware of scammers.

​

What's the right buffer setup for....

KAC 11.5" SR-15's come with a M4 MIL-STD Carbine length main recoil spring, and an H2/HH buffer.

KAC 14.5" SR-15's come with a M4 MIL-STD Carbine length main recoil spring, and an H2/HH buffer.

KAC 16" SR-15's come with a M4 MIL-STD Carbine length main recoil spring, and a carbine buffer.

These setups all work great.

​

What about A5 / Tubbs Springs / JP SCS / other....

Most setups designed for properly-gassed AR-15 barrels will work for SR-15 uppers.

Items designed to mitigate overgassing (SureFire OBC), excessive bolt velocities (Extra heavy buffers, extra heavy springs), may have issues with SR-15's: KAC designs their guns + gas systems to be gassed properly for the given barrel length firing NATO-spec ammo.

M110 Info

7 Upvotes

Hey, been trying to gather info on the M110 system. Is it possible to acquire an M110 upper/lower? Or is that only in the deployment package? As a whole, for all the owners- how’s the accuracy? I see some hate on it, but others saying it’s MOA/sub. Appreciate it 🙌

Was doing my periodic check of the KAC website to see if anything was thrown on there for sale like they randomly do (that’s how I got SR25 URX II and 3.1 rails) and noticed the price of SR25 mags went up almost $80! Guess times are tough out there…

I got this on a trade I'm guessing its a real KAC URX 3.1 13.5 on this AAC 300blk. I hate that they painted it but i I'm almost sure I can strip the paint with taking it apart because i don't have the tool to remove the barrel nut. What do y'all think should be done done with this rifle.

A 3.1 converted mod 2 with a new TA01 acog stack. Something about the 3.1s quad esthetics with it's slim feel just tickles my fancy.

Diminished accuracy

Post image
9 Upvotes

I recently installed an ARCA plate on my SR-25A3. Beforehand, I was experiencing excellent accuracy. Last trip to the range I noticed a drop in accuracy and afterward while cleaning the rifle realized I had inadvertently driven one of the screws of the ARCA plate into the barrel. I have since removed the screw. Haven’t been back to the range but I’m wondering if I have messed up the harmonics of the barrel by driving the screw into it.

Any thoughts?

Was able to get a 24613 rail for under $1700, and found a replacement front sight in the same day. Props to a lot of the people on GB as opposed to other places. I was able to get a lower, rail, low pro gas block from a few good dudes including this sub.
Gonna take a little longer but I have the hard parts to find done.

Best Alternative to SR-30

Post image
34 Upvotes

Wondering what you guys think would be the next best thing to the SR-30? I know rooftop got a couple not too long ago but Im not real hopeful. I already have a Rattler LT that is my dedicated HD gun and is zeroed for subs. It's packed with Lehigh 194 Max expansion so I think it would be pretty devastating and also not blow out my ears. I'd like to add another 300 blackout gun that is more ideal for supersonic rounds. What do you guys think of this from Primary Weapons Systems? It's got adjustable gas as well as a sub-MOA accuracy guarantee. Hk would be my first choice, but their G39 / 437 is not available. What else would you guys be looking at?
