Flash Supp?

[straight-shooter]

I think the situtation is the guy is retired and does this on the side. Also he works out of his pole barn so i imagine not much overhead.

Here is his setup he uses when he threads ...

and a sample of his work

This is a quote from his website... Barrels are threaded concentric to the bore using a single point tool on a metal lathe.

No additional charge to Shorten and re crown your barrel.

So long as the bbl is 16" long when finished.

Well, so much for the 15-22 handgun

Pay the tax and u can shortin all you want... looks like good work

In that pic he is using a 3 jaw chuck ... makes it really hard to indicate in the bore when you can't move the jaws individually to indicate it in but maybe he has a 4 jaw and uses it, its just not in the pic..

Yeah, hard tellin' what he was setup doing when he took that photo.

sounds about right.. avoid anywhere that "turns on centers" unless they are going to rechamber and recrown the barrel.. i allways recrown because the factory crown creates a sharp edge to the threads so an 11* target crown fixes all that and no i dont charge extra for that and neither should any other company

what does "turns on centers" mean? and recrown?

 

[BELT_FED]

Its where u place a center point in the lathe chuck and 1 in the tail stop then pinch the barrel between those 2 point placing pressure on the crown and chamber then they attach a dog leg to the barrel and use that to turn the barrel.... or the chuck up on the barrels breech area and run a live stop in the crown placing a lot of pressure on it...both these setups easily damage some of the barrels most critical areas

 

[BELT_FED]

I should say that those methods do work for high end barrels cause they r made from a much harder material than production 22 barrels r made of.... its still putting pressure in places you shouldn't...

I see what you are saying

Just received my barrel back... lookin' good! thank you to Jim at JPgrips

New here and just got back from the Dealer where I got my new 15-22 and it came with a suppressor installed already. All the 15-22's they in the store had suppressors on them. Is S&W changing up and all will have them?

Unless you live in a communist state where gun owners are oppressed.

Smith has compliant and non-compliant models available now.

Another Satisfied jpgrips customer

I sent mine to JPgrips on Straight Shooters recommendation. Got it back in a week. $49 includes return shipping. If you have to ship your entire upper like I did then it is another $24. http://www.jpgrips.com.

I sent him this DPMS Flash Hider ($5.69) and crush washer ($2.19) which he installed for me. He did a really great job.

Great looking rifle indeed.

Looking good there DavidRSA.... glad you are happy with the thread job!

Belt-Fed,

So what method would you use to machine the barrel? You don't have to speak in laymen terminology, I went to school for Machine Trades.

I didn't check the barrel at the tip to see if it had any taper. If not, couldn't you just chuck up at the end of the barrel assuming your headstock can clear the chamber on the barrel and use a 4J and indicate it in?

Or.... You could throw in on a CNC Mill and Mill the treads on! (I've seen that done before, seems whacky to me)

 

[BELT_FED]

either way works... as long as you indicate in the bore not the o.d. ... circular interp. is the term. you were looking for on the cnc mill... most cnc mills now have a good canned cycle to do it for you all it needs to know is where to do it... i set up with a 4 jaw and a jig to indicate the bore and single point them... or just for ****s ans giggles you can put it in a turn mill and turn it while you circular interp. it by using polar cords. or you can burn them on a e.d.m. if your just looking for something to keep you on your toes

There are two tools I don't like in a Machine Shop.... The EDM and the Surface Grinder, don't ask how I developed such opinions!

I bought my 2'nd M&P with the factory installed flash hider. Here it is with my other favorite 22. If this new M&P proves to be as troublefree and accurate as my early one I'm going to be very happy.
