Avalanche !!! I need to sell some chit.

[Meketrefe]

Last night I am moving a large shelve in the basement wo realizing I had a huge stack of rufle barrels supporte by the other shelve. So when they started to roll many ended on top of me. Luckily I had a bunch of empty cardboard boxes below so nothing hit the ground or my toes! Nothing was damaged. But it was scary for a minute and meade me realize I have to sell some stuff. If you need a nice barrel chambered let me know. I have 233, 6mm, 6.5, 30 cal, 35 cal blanks and some already chambered. I also have a system that allows to use the savage barrel nut to easlily rechamber your rifle whether it is a savage, remingnton or others including ruger PR. Also M1a, garand, etc....
I need to clean up. It is hard to move around.
T,
Perhaps we should rebarrel that spanish mauser and make it a project for a fine restoration?

I also have a system to do easy rebarrel with supermatch wide shank and heavy profile. This allows the barrel to be 1.160 in the chamber area and forward vs 1.060 even with the barrel nut.
One can also use a ar heavy duty castle nut for a nice tactical setup.
Those nuts are theaded to 1.3/16-16 tpi and can secure a barrel very nicely at 60ft-lb that is bad azz.
So even with the Savage small shank or reminton 700 one has a much stronger chamber and rifle. This is ideal for.magnums but alsofor the average caliber. A lot more meat around the bone!

Color me intrigued.

Color me intrigued.

Normally shanks are threaded in one single diameter matching the threads in the action.
However if you step up after the recoil lug section (that is not threaded) you can bring a larger diameter barrel nut that
is going to give the extra chamber support and heavier barrel profile. This helps with both strength and a much harder to heat barrel so
in rapid and long strings of fire the barrel will not warm up so easily. also a wider barrel is a more accurate one for the same lenght
the same way a shorter barrel is a more accurate wide for the same width. This doesn't mean that a long thin barrel cannot be accurate
but those wider and/or shorter barrels will have more accuracy nodes though the harmonics process.
If you look at the LRP (Long Range Precision Rilfle) savage makes, they use the more rigid beefed up action with the large shank even for their
smaller calibers in 243 and 6.5mm. In fact with those dimensions in Short Action is more rigid than the 338 Lapua magnum long action.



LRP in 243, 260rem, 6.5 creedmore share large shank SA platfrom. A bit heavier but it is worth every extra ounce...




This extra meat ahead of the chamber is key to sustained repeatable precission. This way we can have a quick change system that
challenges the tipical headspace system of the R700 and others. I think the Ruger precission rifle made a mistake not going this way
but there is a solution, that is what I have created.

Let me see if I can get some pics of the cut outs I have.

I was hoping you were talking AR platform.

I was hoping you were talking AR platform.

In the AR platform is the same thing the only is that no barrel nut is needed because the assembly with the extension is designed to be serviced or swapped as needed.
But as soon as the forward section of the tenon is wider (heavy profile) this will make a more accurate barrel (potentially) for the same length. I think .920 gas blocks are
overkill and .875 more appropriate. Although I feel there should be a standard for .800 or .825 that is plenty for target.

The biggest flaw with the AR resides in the receiver. No matter how expensive the receiver they all have the same dimensions at the critical point of union. They have to for the barrel nut to work and since many handguards bolt to the barrel nut that is an area that is compromised unless one has an integral system. I can show you when putting some down pressure
sometimes people shooting prone a bit downhill you can put a couple of thousands of flex on the reciever that will have an effect in the point of impact.

I also found that by choosing a top rail for the handguards one could easily bridge both with a sturdy raiser (it doesn't have to be a large one) and this will help with the
overall rigidity. Never use the scope mount nor touch the scope mounting system with this. It should be totally insulated ans why cantilever mounts are popular these
days when optics need to go forward.

Are these AR barrels?

Some are. What are you looking for?

Thinking about another build, not sure if I want to go 7.5 or 24 inch.

Thinking about another build, not sure if I want to go 7.5 or 24 inch.

quite a difference there.
I think there are not many calibers worth neither 7" or 24 inches in an AR.
I think 22 inches is a sweet spot for the 223 and 21 inches for the 6x45. If you look at all the load data there is very little advantange vs. increased weight and length/bulkiness.
For a 10" the 35 AR Gunner I built is the ticket. 180gr bullets coming out at 2300fps! One can hunt with some authority with that.
147fmjs pistol bullet are so much fun too. They clock 2,500fps on the 10" pistol when loaded with lil-gun.

...just trowing some ideas out there... you know, to feed the wild horse ( shooting enthusiast's brain)

The only reason I am thinking about the 7 is for a PBG. That is a patrol bag gun.

What about a pistol caliber? The 9x25 Dillon is bad azz. It will put a lot of speed and power in 7 inches.
Plus you have lowers that take the 10mm glock magazines that is what the Dillon needs. The 10mm will work fine too with lots
of power but the speed of the 9x25 is better to drill through glass, doors, etc...plus the section of the 9mm bullets solids at
those speeds is pretty simliar to the 10mm so broad wounding and plenty of penetration.

Or what about the same in 357 SIG? Milder but more popular and still 357 magnum power. The US secret service choice for
a good reason.
They also have lowers that will take the G22 40SW glock magazines that is what the 357SIG uses.

[Brendan2904]

Yeah, things got nice. Need an upper with a 7.5 barrel in 223 wylde. Got any of those?
