Suppressors Durability of a thread on and so on

[THE MGD]

Had a chat with my gunsmith about theading my project rifle.

Project Rifle:
Remington 700 adl in 308 win 22" barrel 1:10 standard sporter barrel

Suppressor YHM SS 30 cal Phantom thread mount, unsure of thread size (still waiting on the stamp)

My gunsmith claims the following: the threads are angled and weak and I will quickly wear out my threads if I do not use a muzzle break attachment adapter. The sporter barrel is to thin to make good threading. And finally there is no good "safe" subsonic loads for 308.

The last statement raised my concern and questions the validations of the previous 2. Can't I just use a thread size adapter as a disposable buffer to my actual rifle theads?

I do plan on using it on at least 2 rifles

He also suggest cutting down the barrel length to 18". As this is a bench target rifle primarily I am opposed to losing any of my length, and I have no issues on weight.

Any insight?

Re: Durability of a thread on and so on

Ok their are plenty of safe .308 subsonic loads. If your threads are done correctly the threads will not wear out.

Now for the sporter barrel being to thin to thread that can be the truth. Usually 30 cals are threaded 5/8x24 TPI, so if your barrel is not large at the muzzel you may have a problem. If you have a sporter barrel and are going to hang a suppressor on it, it is going to have a big POI shift compared to a target or Varmit contor barrel and if this is a target/bench gun I would want a heavier barrel on it anyway.

Wow talk about funny.

you want to use a hunting rig for bench/target

Now you want to hang a CAN from that pencil like barrel

tell me this is a spoof post plzzzzzzzzzz

Re: Durability of a thread on and so on

+1 Jedi, I work at a buddy's gun store here in Auburn (The Firing Pin) every now and then, and we had a guy come in asking about AAC's then went to say that he had a 26" sporter barrel, and he wanted to attach a direct thread suppressor onto the end of it. My only suggestion was to call my gunsmith and ask if the barrel would have enough heft at around 20" to cut proper threads. I haven't heard back from him yet, but his rig was just for coyotes....not a target rifle. Sporter barrels are not meant for target shooting with long strings. I would suggest getting a thicker barrel if you want to shoot targets AND hang a can off the end. If you were shooting yotes and were only taking a couple shots here and there then it makes a little more sense.

Not a joke jedi, I dont know why youre laughing? [serious face]..

Re: Durability of a thread on and so on

My shots are on average are about 4-6 mins apart, shooting 5 round groups , with practice shots I average about 8-10 rounds a day/ session.
Coyotes and boars are taken with a diffrent rifle (.22 mag) but if the oppertunity presents itself ill try with the project build

Re: Durability of a thread on and so on

Just a general question: Why so long between shots?

 

[THE MGD]

Re: Durability of a thread on and so on

Shrug* no rush, why waste rounds? Gives me time to think , sometimes ill take a break and walk around, it breaks my rhythm so each shot feels like the first shot. (reason being ; most game animals only want to give me 1 shot, so I make it count)

Re: Durability of a thread on and so on

As Buckeye stated your barrel could be too small in diameter to thread to 5/8-24 and still have enough shoulder for the can to index against. As for the threads wearing out and no safe sub-sonic loads for 308, that's just straight up bullshit! As long as the threads are cut properly they will never wear out, and we all know there are lots of safe sub-sonic loads for a 308. I'd find another smith that knows what he's talking about and go from there. I can direct you to a few good ones if you want to shoot me a pm.

Re: Durability of a thread on and so on

If its a bench/target rifle you will probably want something heavier than a sporter barrel. With the heavier barrel the 5/8-24 threads won't be a problem. The other stuff is BS find another smith!

 

[THE MGD]

Re: Durability of a thread on and so on

Is there a adapter conversion solution I could use to go from a smaller thread to the 5/8
(simular to ratchet or pipe fitting adapters)

Eventually ill upgrade to a heavier barrell but thats not in my current budget, and im told I might as well buy a new rifle going that route.

Re: Durability of a thread on and so on

what part of this are you not understanding?

wrong barrel for a CAN
wrong barrel for bench/target rifle

Its a hunting rig with a pencil barrel use it for its intended purpose and its fine

But your trying to make a silk purse from a pigs ear

swap the barrel or buy something with a heavy barrel

Re: Durability of a thread on and so on

You may be able to salvage the project by cutting to 18" and threading. If you measure at 18" you'll be able to know if there is enough material or not.

If someone threaded it without telling you that the thread would not be useable, they should probably cover threading it again to make it serviceable.

At 18" the barrel will be more rigid so hanging a suppressor on it shouldn't be an issue.

The M14 has a pencil barrel and that hasn't stopped people from putting suppressors on them successfully.

From what I gather the minimum diameter is .720". A quick measurement of mine shows .625 @ 22" and .640 @ 18". Ruling it out mathmatically. meh, excuse enough for another project build. Ill be looking for some used / new threaded bull barrel rifles. Already got the stock , scope, bipod, etc should just be a easy drop in swap.
Thanks to all the supportive answers I put the others on ignore

Good philosophy, MGD, my style is the same.
However, I don't think you will be happy with the results if you continue on your chosen path. I don't think there is enough material in your barrel to effect your plans safely.

Good shooting . . .

So why not just get a new barrel? If the reciever is good you'd probably come out cheaper with just the new barrel. Not to mention having one that you know the condition of, or the ability to select your twist rate and riffling. If you want to shoot subsonics a 1:12 twist rate is definitely not ideal. But hey it's your money right

I dont have the tools to swap my own barrel and my local gun smith charges 500$ to change it. So 315$ - barrel, 500$ - smithing, 150$ threading =965$

Or

New project $650?
Looks like threading is the same? Any reason not to get this, or cheaper / better deal (cheaper)

The only reason I could see to NOT get another weapon is if my wife is drawing a bead on me with my previous purchase......not having enough money has never stopped me before.......crap...my lights just went out.....

Re: Durability of a thread on and so on

Well I meant are there any issues known with this rifle, specifically with shooting suppressed with a YHM SS 30CAL direct thread on

Can not comment on the YHM products, however as a general comment, the barrel thickness of that rifle is not an issue with regards to suppressor use, even though it is too thin for the 5/8"x24 UNEF thread.

Over the years we have manufactured tens of thousands of suppressors with the appropriate size metric threads for the thinner profile hunting rifles, the most common threading being the M14x1, either with a spigot alignment surface or one without it.
