KIDD supergrade Charger or slipfit Charger barrels



Log in to see fewer ads
So, I have been looking at 10/22 receivers for the past couple months, due in large part to the fact that I can’t find the elusive 8 inch 10/22 charger with picatiny stock mount Ruger now makes. They seem to have been out of stock for months now.

All of the cheaper examples are sold out, Specifically BROWNELLS BRN22 receivers for $90. Any other receiver of any repute are going for at least $200.

So if I was going to potentially spend that much, then I think I would go with my ultimate build and create a Kidd Supergrade premium Charger.

I like the quick change barrel system for the supergrade recievers and if I’m going to spend the money, I might as well get everything I want.

Unfortunately, KIDD does not currently make their Shorter barrels for the Supergrade premium receiver

Would anyone else be interested in a KIDD 6 or 8 inch barrel or a supergrade Charger?

Just curious if I am the only one. I wonder what it would take to put together a group buy?

Kidd does make .920" pistol barrels in 6" and 10" .lengths that work with any standard 10/22 or charger receiver. They come in stainless and black with a polished or bead blasted finish. If by slip fit you mean classic/standard receivers vs a takedown or supergrade then those will work for you.

I would like it personally if they offered their supergrade barrels in pistol lengths because I would SBR my supergrade in a heartbeat.

I think by "slip fit" the OP means that there will be no fitting required to either part to mate them together properly and easily.

Joining my Brownells BRN-22R receiver with a KIDD 6" blued barrel required fitting; I chose to open the diameter of the receiver bore vs. reducing the diameter of the KIDD barrel tenon for the proper interference fit, then used heat (on the receiver bore) and cold (on the barrel) to join the two effortlessly by hand, with no hammer or mallet required.

I don't have a tremendous amount of experience with different 10/22 aftermarket receivers/barrels, so other brands of receiver and barrel may not require fitting. A simply Google search will reveal the experiences of others who have travelled down this path with every possible variation of parts, so do your homework before deciding on what components to purchase so you won't be surprised when it comes time to assemble them.

I was a little confused by the op's post as well. I can only assume that he was referring to the fact that they don't make a Supergrade Charger barrel because obviously they do make slip fit charger barrels.

As far as putting them together there is no need to remove any material from the receiver or the barrel no matter how much it seems like they're not going to fit together. I've assembled dozens of 10/22 style barrels with pretty much every barrel/receiver combination out there and I've never had one not go together after freezing the barrel and heating the receiver. And I've had some that were extremely tight before adding heat to them.

Well originally Kidd had two different receivers they offered, the “Classic Slip Fit” and their “Threaded”. Those just differed in the way the barrel attached to the receiver. Now the Supergrade has replaced the threaded version but that term “slip fit” they still use on their classic standard 10/22 receivers. The fact that they used an oversized barrel shank and that it requires fitting is not uncommon with 10/22 barrels.

Kidd used to offer a Charger in their old style thread in Supergrade?

They do use an oversized barrel shank, but it does not require "fitting". At least not in the way of removing any material from the barrel or receiver.

That may be so when installing a KIDD barrel into a KIDD receiver, but when I measured the OD of my 6" KIDD barrel tenon and compared that dimension to the ID of the receiver bore of my Brownells BRN-22R receiver, the difference in dimension was simply too great for an interference fit, so I enlarged the receiver bore to be .0005" smaller than the barrel tenon.

To visualize my point, here were the dimensions of each component:

Brownells BRN-22R receiver bore ID = 0.6835"
KIDD 6" blued barrel tenon OD = 0.6865"

The maths 0.6865 - 0.6835 = 0.003

The receiver bore was 0.003" smaller in diameter than the OD of the KIDD barrel tenon, so there was no way I was going to attempt hammering my new receiver over the barrel; it's my opinion that the receiver would have cracked or broken, and I much prefer working like a gentleman and not a caveman

If you felt the need to do it then by all means. But I've fit OEM Ruger barrels into Kidd receivers just using heat. Not sure what the sizes are but an OEM Ruger barrel tenon is about .002 larger than a Kidd barrel tenon, and the Kidd receiver hole is smaller than a Kidd barrel tenon.

The hardest one I ever did was an OEM Ruger barrel in a Feddersen receiver. I honestly didn't think there was even a chance they were going to fit. But I was able to finally get them together using just a cheap hair dryer and some anti-seize.

Correction

Well dang it. That’s my fault for being unclear (And uniformed)

What I was trying to ask about was Supergrade premium compatible barrels in 6, 8 or 10 inch lengths.

Before the ATF proposed tighter regulation on Arm Braces, I was really liking the idea of building my ultimate Charger, a Kidd Supergrade Charger.

Unfortunately Kidd does not make short barrels for the Supergrade premium receiver.

I was wondering if anyone else would be interested.

What? No, I didn't say they offered a Charger just that they used to offer a different receivers the slip-fit and the old threaded supegrade.

If I felt the need? As I stated, the receiver bore of my Brownells BRN-22R receiver was 0.003" smaller than the barrel tenon of the KIDD barrel, which by normal engineering standards is too great of a difference for a proper interference fit, even moreso considering they were dissimilar materials; the standard interference fit is 5 ten thousandths (0.0005"), or half a thousandth of an inch in diameter. I have a background in manufacturing, and I prefer using proper methods when it comes to fitting parts together in lieu of brute force and lubricants.

The dimensional difference I was able to obtain between parts along with the application of heat and cold allowed me to install the barrel by hand using absolutely no force whatsoever. And even after the parts cooled and I realized that the alignment of the extractor cut was slightly off, the application of some extra heat to the receiver bore area allowed the barrel to be rotated, again by hand, using no tools.

If someone wants to hammer their receiver over their barrel that's their choice. The fact that Tony KIDD does it in his installation video didn't sway me from taking the steps I did for what I consider to be an easier and more correct method of installation that requires no force whatsoever and doesn't produce any galling of materials...just a dry and proper interference fit.

Below is an image of the receiver bore prior to barrel installation:


I suppose I could have left the receiver alone and heated it up enough without melting it and froze the barrel with LN2 at -320F before assembling the two, but I'm fairly confident that when both reached ambiant temperature the aluminum receiver would have cracked from the stresses of the steel barrel tenon pushing outwards radially against it.

It's well known that there can be major differences in 10/22 reciever bore and barrel tenon dimensions between manufacturers, with each combination requiring a different course of action when it came time to fit these two components together. If during my Charger build I'd found the difference between receiver bore and barrel tenon to be within recommended tolerances I would have proceeded differently, but such was not the case.

A 'couple things worth mentioning...before I'd received the 6" KIDD barrel I found a used 16" OEM Ruger 10/22 barrel during a pawn shop visit, so I purchased it to have around just in case I one day decided to put together a simple rifle. When I got home with it I was curious to see if it would fit into the Brownells receiver; well, it fit alright...it literally dropped into the receiver with absolutely no effort whatsoever; by comparison, the KIDD barrel couldn't even be started.

Then there was the Ruger Charger pistol that I'd seen forever in another pawn shop. The very first thing I noticed about it was its Tactical Solutions aftermarket barrel, which then led me to see that both corners of the front of the reciever and the top rear of the reciever were smashed in from a hammer; such severe displacement of material could only have come from some caveman using a steel hammer to force the receiver over the barrel to install it, then hammering it off probably because the extractor wasn't aligned with the extractor cut of the barrel on the "first try". I quickly handed it back and thought to myself what a shame, that Charger is going to be here forever and ever.

So, pick yer poison!
