Wilson Combat flatwire spring/Kynshot fit problem? Did WC change something?

- I've received several reports in the last few days that people are having problems fitting the Wilson Combat Carbine Flatwire spring on wide-body Kynshot hydraulic buffers. It should slide right in without any problem. I show how they should fit using my Wilson Combat springs and Kynshot buffers.
I wear ear plugs, or muffs, or both, in every shooting video.

I just ordered all of my parts for an upper yesterday including the Wilson spring and a 5015 buffer. I will put another comment here in a few days when it comes in
Let me know!
Still ongoing, I was wondering
@@aims2sadome the Wilson spring was too tight and added resistance so I swapped the spring with the flat wire from my AR-15 and it fit like it should. Can't remember what brand it was
@@ethanlomshek6778 this is my first personal AR. I wish I had a spare 😭
I ended up using a Strike Industries flat wire spring on mine with the Kynshot and it worked flawlessly. It's a Colt 635 clone build with a A5 tube and two spacers.
Strike is tight (lube the buffer!) but apparently not as tight as the new Wilsons!
Thanks for the heads-up. I'll watch your channel for your follow-up before I get my soft-shooting 9mm pcc parts.
Or just get a Tubb Lightweight, Tubb Carbine, or MidwayUSA AR Stoner flatwire. They're all good to go, but the Midway is a little noisier in the tube.
Thanks for looking into this! I’ll wait to hear back before ordering another WC spring or just going with the Stoner or Tubb lightweight option. I had ordered the WC spring to use on the 5015HD and it would not fit without a lot of effort.
Thanks for the video, I just got my parts in on Saturday, May 11 and after seeing your video, check them to find that I am also having a problem with the buffer spring fitting on a RB 5007. That is also a problem because I ordered the 5015. Thanks for your video.
Sorry to hear that! Could you let me know where you ordered the WC spring from that was too tight? Thanks!
Appreciate the info like always! Unfortunately saw this after I got my delivery today. Ordered 3 of these to swap out standard springs and not a single one fit any of the buffers
Sorry to hear that. I ordered one this week to check the diameters.
It might help to publish the exact measured buffer diameters of your buffers .
Already did! blowback9.wordpress.com/2023/05/14/kynshot-hydraulic-buffers-comparison/ And here's the springs: blowback9.wordpress.com/2023/03/03/flat-wire-spring-comparison/
@@Blowback9 wow that’s great! Thanks for the effort. Now we have a better overview than the manufacturer has 🤣
I got the RB5015HD buffer and Wilson Combat spring in today, and it is too tight. When I compress the spring after it's on the buffer, it does not return to fully relaxed. Although when it is compressed a certain amount, the spring widens and allows the buffer to slip through the coils like it should. I wonder if it would be compressed enough in the buffer tube at its longest point where it wouldn't be an issue. the only way to check would be if you take one of your buffer tubes with cuts for your slow mo video and rack the bolt slowly and watch the spring around the buffer.
Possibly, but that's not optimal. It should slip right in with very little effort. WC still hasn't gotten back to me....
@@Blowback9 just curious, on your WC springs, are the edges of the spring rounded over, Or is it a cut, square edge? Mine is rounded over.
@@ethanlomshek6778 It looks like the wire is just sheared off.
@@Blowback9 I'm willing to bet they switched to a wire that was smashed flat instead of cut and then formed into a spring. That rounded edge sticks inward just enough to be too tight. Thanks for the replies, keep up the great content!
@@ethanlomshek6778 OH, I'm sorry - I thought you meant at the ends. The outside and inside edges are indeed rounded over.
Just put my stuff together last week, and I was wondering why it was so difficult putting the buffer (5015 heavy buffer) into the flat spring
Where did you order the WC spring from?
@@Blowback9 I believe optic planet
Great video! Maybe just damage in shipping done to the spring?
5 reports so far......
Could I use a dremel to bore out the inside of a flatwire spring so it can fit over a kynshot 5015? I am from Canada where our parts availability is mediocre and the strike industries spring is the only flatwire available to me. It would only need like 0.01” removed.
I must have lucked out when i got mine
I know you've been recommending the WC spring but I was disappointed by it. It works fine but it's no quieter than a standard spring. I switched to an Armaspec braided spring which is significantly quieter, though it is a very snug fit on my KVP buffer.
Thanks for your input! I've found it to be much quieter, but I'll look into that spring.
I just received a WC flat wire spring for my kynshot RB5015HD. It slid on nice and smooth. I test fired about 5 rounds through it (flip flops off my deck.) Smacked steel at 72 yards and locked back. Springfield 9mm pcc. Maybe it was NOS?
Could be - the way the reports are coming in, I'd suspect so.
I saw this 1 day after ordering the Wilson Combat flatwire spring and Kynshot buffer. I guess we will see.
Please let me know if it works or if it's really tight.
@@Blowback9 Really tight from both ends, scratched up the Kynshot buffer getting it on.
I measured the Kynshot Buffer diameter it is .760, a standard buffer is .687 so I measured the inner diameter of the wilson flat wire spring its is .745 to .749 depending on where I measure it.
@@dave_bob That's definitely tighter than mine. Mine are around .767-.771 ID
@@Blowback9 I ordered the Tubb's Lightweight Flatwire, Thanks for all your work and efforts to further the community.
Just got my Wilson spring and it is super tight on my 5015. I tried both sides. Gonna need to get something else.
Sorry it gave you trouble - the new ones seem to be a big problem. Tubb Lightweight or MidwayUSA AR Stoner flatwires are my current picks.
@@Blowback9 Yeah I’m gonna try one of those. Have you had a better experience with one or the other?
@@mikehenry4425 The AR Stoner is a little more noisy in the tube, but less expensive. I like the Tubb Lightweight, myself.
Where did you order the WC spring from?
@@Blowback9 Midway USA earlier this may
I tried the strike and it barely fits over the Kynshot 5015 buffer. I have a Wilson coming, hope it fits.
Let me know! The Strike it tight, but based on what I'm hearing, the Wilson may now be even tighter.
@@Blowback9 my new Wilson spring fits on one side and tight on the other. Gonna go put some rds through it today to see if it feels any different from the Spikes.
Got mine in yesterday and it won't fit. Can I run just a standard AR15 round wire buffer spring with this system until I figure out an alternative? Keep in mind the round wire spring is about 3 inches shorter before being compressed.
Yes! A round wire spring should work just fine, but it may be more noisy in the tube.
@@Blowback9 Thanks for the quick reply!
Yea doesn't work.
Used the spring that came with the firearm, do not twist it on it WILL bind.
