ar problems

[Sin-ster]

As long as it is put on straight and screws Loc-Tited, there should be no issues. Have you had one fail?

The closest I've come to a failed clamp on was someone who had no reason to lie to me, who saw two of the same basic design fail-- both aluminum, both vertically clamped.

I've seen a set screw one fail, as per the last post. But there's no telling if the barrel was dimpled properly or not from the beginning-- we just saw the block canted, and got the word later from the owner as to what had happened.

I'd just assume avoid the things that logically could be a problem, though-- specifically, the aluminum block against a steel barrel, at the temperatures that we're discussing. Otherwise, I'm totally on your side-- you'll torque the barrel out of the receiver before you move a properly installed block.

ETA-- I seem to recall reading something on Sniper's Hide not terribly long ago about the set screw types altering the barrel's dimensions in one way, shape or form-- but along with a lot of my other handy AR links, it was lost to the great HD crash of 2011.

So you're ok with a steel clamp on fsb?

Bo, didn't see the word "aluminum" in your earlier post (worked last night and no sleep today). Aluminum gas blocks or muzzle brakes have no place on an AR.

That's the dual thumbs up on that one, Demon. But as with a lot of these things, a lot of it's in the install. Clean surfaces (completely degreased being especially key), proper alignment, appropriate torque and heat resistance Loctite are going to be the keys, for sure; staking the nuts is added protection, but I'd probably run the gun for a while with some witness marks to see if it was moving in that regard before I went too crazy, especially as these seems like a "temp" fix.

And I'm very thankful for all the advice I've been given in this thread JWG. I'm thinking about getting the clamp on fsb and seeing how that does for the time being. Ultimately I want to upgrade the system to a new barrel with a proper fsb. I just dont have the funds to do that at this time.

How much funds do you have? I really think you will just be wasting money on useless parts when it's all said and done unless you fix it the way you want it/it should be fixed, in the end. Maybe worth saving a month or two for, rather than wasting?

My first plan of action is to try different ammo and lube the bolt up until its dripping. A couple boxes of ammo are cheaper than either of the other two options. Maybe it'll work, I doubt it but I'm hopeful. Secondly, I'd rather have a working gun than a non working gun, even if the fix is temporary. In the event that options 1 and 2 fail, I can get a new barrel with FSB already installed, sell the clamp fsb, and use the barrel as a T-ball bat for my 4yo.

Neither do plastic POS lowers.But apparently,that is the big craze lol..
They just have to hope no one accidentally shoots their lower with any
kind of real bullet...

 

[4x4demon]

I dont get shot at regularly so the plastic lower is not really an issue for me

 

[scooterj]

It amazes me that every time someone asks for help, people have to $h1t on him or his thread.

 

[4x4demon]

It's cool, I've been on enough forums long enough to understand that some people are just negative in their posting style. I've been on tigerdroppings since 2007 and if you cant look past the negativity you'll kill yourself over there.

 

[gmshooter]

I thought that was you over there!! Rough freaking crowd over there.

Yes it is. Its why I hardly post anymore. The stupid is strong around here the last year or so.

 

[4x4demon]

Yea that's me gm. Do you post or just lurk?

Unfortunatly stupid is running rampant everywhere.

 

[gmshooter]

Mainly lurk they have some funny crap over there. I usually post on the outdoor board.

 

[4x4demon]

Yea, once they created the ob I almost post exclusively over there. The raw sewage from the OT has been seaping over there but its a great group of guys.

Resurecting this thread: took the ar to the camp this weekend after cleaning and lubing it up real well. The first two rounds shot and ejected fine. After that it was ejecting the rounds but not picking up a new one. I shot it sideways while looking at the bolt, it does appear to be short stroking on the tula ammo. I'm going to pick up some higher quality stuff this week and see how it does. Though the barrel and fsb seem to be mared beyond repair they are lined up right. Maybe new ammo will fix my issue.

Good luck. Look at it this way, at least you're learning the ins and outs of the platform.

Have you heard back from the seller at all? I'm curious what he has to say about all this.

 

[4x4demon]

I havent tried to reach out to him since the initial failure. I did remember he's the member nineteenhundred (sp) on here. I need to pm him. I'm still of the mind that this may be something simple with a brand new lower and shitty ammo.

Then I'm sure you fit in well at tigerdroppings.

You wanna try and run that by me again? What exactly are you implying?
