Awesome Accessory
I purchased these spikes for my new KSG 410ga shotgun. Great quality & they are sharp!!
Unfortunately these didn't fit the 410ga & the website didn't state otherwise. I paid for the return shipping, but didn't have to pay for the restocking fee.
Just wish it was stated before hand.
Very cool
These things just look so cool on the KSG. Are they practical? Maybe, maybe not. But I will say that these make an already mean looking firearm look even meaner. HUZZAH to mcarbo!!!!
Nice Addition to the KSG
Great Product with very fast shipping. Adds function, and style to the KSG. It was very easy to add them to the firearm.
Great quality! Makes my KSG look sick!
Bad ass addiction to my rig!
Being a retired fighter jet mechanic and firearms enthusiast, I'm always finding ways to tinker and modify my firearms. I found MCARBO searching the web for KSG upgrades and I was hooked. The bayonet spikes were extremely simple to install and look mean! The material is extremely well crafted and finished flawlessly. HIGHLY RECOMMEND THESE!

Good fit and functionality. Not too heavy and keeps the gun short!
Great product
They arrived super quick the only thing is I haven't installed them because I didn't realize the tools I need that would be beneficial to installing them. I will buy piece by piece till I can install them.
Great Product!
Product is as described and makes my KSG look mean. I definitely recommend the product.
Besides the spikes what else do I need to properly install this product? The video is super confusing and goes into other stuff that I’m not sure I need to do to install these spikes.
M*CARBO Buttstock Spikes Kit and Phillips or Torx screwdriver (depending on your stock hardware)
explain the purpose of the jam nut ??
Please contact our Customer Service at help@mcarbo.com to discuss this.
Will these work on the . 410 model?
No – the KSG Bayonet Spikes are not compatible with the KSG .410. - the KSG .410 has a smaller barrel and different barrel lug spacing
Will these fit a Smith & Wesson M&P 12 ?
No – the KEL-TEC KSG Bayonet Spikes are not compatible with the Smith & Wesson M&P 12. - The spike kit is specifically designed to mount to the KSG’s front sling loop bolt pattern and muzzle cap interface.

Will something like this be available for the KS7? Maybe modified magazine cover. ;)
We do not currently have anything in the pipeline for this, but are actively researching options
Repeating Nicks question, do these screw directly into the KSG410 as well?
No – the KSG Bayonet Spikes are not compatible with the KSG .410. - the KSG .410 has a smaller barrel and different barrel lug spacing
Is anything else required to install these on the DP12?
But in the description, it says they fit the Dp-12.
the KEL-TEC KSG Bayonet Spikes will not directly fit the DP-12. - The DP-12 uses a different barrel nut and magazine tube layout, with non-threaded end caps that are not cross-compatible with KSG hardware.
Will this item fit on the new KSG 410?
No – the KSG Bayonet Spikes are not compatible with the KSG .410. - the KSG .410 has a smaller barrel and different barrel lug spacing
Is the breacher barrel not available? I can’t find it to add to my cart

What is the effective length of these spikes when installed? I'm considering the Hi-tech short "Crusher" muzzle, which is 0.9" from the end of the thread, and I'm trying to figure out if that muzzle will be short enough.
Will this fit my smith and Wesson m&p12 ?
can you just screw in the spikes and not do the whole other process on the video?
For the installation of the ksg bayonet spikes, is there anything additional that I need to purchase to install them or do they just screw in?
We recomend doing it it as the video show
How come they don’t make the exstensions for the spikes anymore? Every ware I looke they where out of stock or discontinued I asked customer device at several different companies and they where very unhappy two they said people were always looking for them and it was a good selling product to go along with the spikes to get beyond the surpressor or muzzle device now we have nothing it really is a great loss!
We are sorry for the inconvenience, but the extensions were discontinued a while back due to very low sales combined with the cost to maintain inventory.
Will this work on the ks7 with the keltec barrel extension?
KSG Bayonet Spikes only function on the KSG firearm.
Does MCARBO still make the extensions for the bayonet spikes?
What can I do to get two of them? Thank you.

No Sir, unfortunately we discontinued the extensions due to low overall demand. Not something we expect to make in the future.
