I need a new gas tube!

[Jotun30]

I am installing a Midwest Industries rail on my M&P 10. I messed up the removal of the gas tube from the high profile railed gas block. I now need a new tube. Will this work?

Rock River Arms 750 Low Profile Gas Block with Rifle Length 12" Gas Tube New | eBay

I called customer service, they said no parts were available, but in the near future they will be making them available to us. I measured my gas tube and it came in at just a hair over 12"... like 1/32"

Original gas tube is proprietary tube with length similar to but not the same as mid length gas system.

 

[Woodman90]

I have been told but have not confirmed myself that the S&W part number is 430710000

 

[Jotun30]

That's good to know. I don't want to just buy a rifle length tube, and cut it down. I believe it would leak too much gas or otherwise cause the rifle to run "dirty"

You might call Black Hole Weaponry. He has the specs and may be able to fix you.

Seems the tubes are somewhere between DPMS and Armalite.

Thanks, I think I will if this gas tube/ gas block assembly doesn't pan out! Gotta try everything!

I think it is a mid length plus 1 inch.

I found this, and have one ordered. We shall see if it works out! AR-10® CARBINE GAS TUBE

Let us know! The fellow at BHW told me (Armalite vs DPMS) one was slightly shorter, the other longer, but I cannot recall the specs.

I am beginning to dislike S&W!
I broke two roll pin punches trying to get the gas tube pin out.
I ended up drilling the pin out, but damaged the gas tube.
Just ordered the Armalite gas tube referenced above, thanks for the link.
I'll let you know how it works when I get it installed.

I should have replied earlier. The armalite tube works perfectly for the m&p 10, at least for my rifle. The tube I linked has performed perfectly for me, I shot 60 rounds today, no malfunctions whatsoever! So if you need a new gas tube for your m&p, thats your bird!

That's exactly what happened to me too! You're going to be golden after you get a new gas block and tube in. What kind of hand guard are you going with?

I ordered the Midwest Industries D.P.M.S. .308 KeyMod 12"
Midwest Industries: DPMS .308 SS-KeyMod Series

I have several of their hanguards on AR-15's.

Received it today, it fits great. You need the extended ejection port rod with it.

Pictures will follow soon.

Great info Jotun30 on part interchange. Glad to hear your rigs is setup. That free float is wicked.

Range Day

Finally made it to the range Sunday.
10 shot 100 yards.
92 degrees and humid!
Using American Eagle 150 grain FMJ.
I am happy with the results.
I do need to practice better breath control.
Now I need to find a 200 yard range.
Any thoughts on a more accurate factory load?

Mine wont do that with 150's.

Try some 168 Vmax or Sierra BTHP.

Nice. If it will do that with 150 gr. wait until you get some good 168 or 165 gr. ammo. You'll likely have sub moa and get that breathing and trigger pull down and they may just touch each other.

Mine LOVES 165 gr. Sierra Game King and 150 shoots about like yours. 145gr. Shoots terrable.

Like others have said; the heavier pills shine out of not only this but most .308

Thanks guys for the feedback.
I picked up some Federal 168 Grain Sierra Match King Boattail Hollow Points.
Next range trip I'll see how they shoot.
