[ARCHIVED THREAD] - Will varmint barrels crack upper receivers?

Posted: 3/7/2006 3:36:27 PM EDT

I was told today by an ar15 smith that a heavy varmint barrel will crack the upper receiver.,Also that I will not get 100% bolt lockup with the barrel, (because of barrel/receiver bend? Is this BS or something I should keep an eye open for ?

Any information would be appreciated,
MickeyJr.

Never heard that one. I've seen varmint bbls as long as 24", never once heard of the barrel "cracking" the upper. The bolt lockup is also something I have never even heard a rumor of, let alone an actual case!

Additionally, I have no idea what the f**k he means by "barrel/receiver" bend. This guy is an AR 'smith?? Are you kidding me?

I call

on this one. Huge.

I have 3 heavy bbl ARs and shoot the hell out of them. Not the slightest problem with any of them and they are all different calibers and different lengths.

Got a name and shop of this clown?

Also, what gun was he trying to sell you instead of an AR-15?

this only applies to the older rubber upper recievers...

too bad i didn't have an ass hat to give to this apparent ass clown...

the only thing i can guess from this is maybe he's mistaking the heavy M4A1 problems with upper receiver issues as a result of over loading the upper with weighted bolt-ons...

as for a heavy barrel - you'll be finer than frog hair...

I've heard of problems with Ruger 10/22's supporting heavy target barrels, but not AR's. Maybe he has his guns mixed up. Either way not someone I would trust to work on my weapons.

I agree..... Us NRA High Power match shooters that shoot spaceguns shoot a 26" heavy barrel!! and there are NO reports of any troubles.. if there were.. you wouldn't see anyone using them for fear of a upper cracking during a match.....

why do gunsmiths always have to ruin their own reputation, by spouting off nonsense bullshit?

Ok, theoretically if you grab the upper reciever and only support the rifle by this part, there will be some bending with a heavy barrel. And if the barrel was heavy enough, it could, in theory, cause the upper to break if it isn't strong enough to support the weight of the barrel.

In reality, I think that if you used a barrel heavy enough to do this you would have other problems to worry about. In fact, I'm not sure you could afford to buy a barrel that would be big enough to do it.

How about some of you engineers do the math and let us know how heavy the barrel would have to be?
