So im removing my barrel...and find that that sucker is on there tight! It wont budge without breaking the upper it feels like.

Is there any hope? or should I get a reciever block?

I went through the same thing. Get the reciever block and save some headache.

You didn't say what set-up you are using right now so it's kinda hard to advise you on where to go from there.

Do you have a barrel nut wrench?

Did you remove the gas tube?

You said you don't have a reciever block so try this. With the bolt/carrier in the upper place it on a carpeted floor wrapped in a towl if you want. Place the barrel nut wrench ( I used a GI one ) on the barrel nut and with a mallet, tap the barrel nut wrench leftie loosey holding the upper flat on the floor with your foot.

Sounds crazy but I've done it plenty of times before I had all the tools to do it right.

If you are serious....

Yes, get a receiver block and barrel wrench, along with a good firmly secured vise at a minimum. If you are swapping barrels you may need a pin punch for the gas tube roll pin, some moly grease, and a gas tube wrench if it is an old setup with lots of carbon buildup.

Ok cool...yea im using a barrel wrench. I didnt think of the bolt+carrier thing, Ill try that.

Thanks!

Depends a lot on how torqued the barrel is.
I had one that some king kong type had put on, took a cheater bar to get it off.
Never could have done it without the block.

I don't recommend half stepping when doing work on a firearm.

Get the block, barrel wrench and some moly grease for re-assembly.

You'll save the lower from damage.

The bolt carrier is only in there to support the thin aluminum walls so it don't deform on you while you work on it.

Make sure that barrel wrench is firmly seated so you don't tear up the teeth on the barrel nut too.

Listen, if you're at the point in this AR lifestyle that you're removing barrels, you'll probably be doing this more than once. You know it's true. Which means you should invest a few bucks in a reciever block, wrench, and a vice - even a cheap chinese one will do. If you try this without the right tools and so much as scratch your rifle, you'll be kicking yourself for not getting the right tools and doing it right.

I've taken the two blocks of wood seen in this pic of my FAL vise and placed them in a bench top vise. I then used a DPMS wrench to unbarrel a Colt A2 receiver with no ill effects. Those are two pieces of oak pallet that I formed a shallow channel in with a dremel across the grain. I now have a receiver block, but this rig was used to remove and reinstall very tight barrel nut with no ill effects.

+1 He hath spake the truth - Don't WECSOG it when changing barrels.

If you have a vise, just wrap the upper in a folded newspaper and clamp it down. Be careful not to crush the upper, but it works pretty well.

I've barreled a large number of uppers at this point, and haven't run into any problems.

[update]

well...shit.

I bought the huge vise and the vise reciever block and the armorers tool, all the right equipment for the job. But the wrench slipped when I was torqing on it and I managed to remove all but half of the tangs on the barrel nut! Now the wrench has nothing to grab onto. So that plan of doing things the right way just went up in smoke.

So I think I might have to put a damn pipe wrench on it and buy a new barrel nut.

What do you think? BTW, even though I screwed shit up- I had alot of fun doing it, im hooked!

oh yea I wrecked my car on the way to get the vise! lol read about it here ....what a day

Which style barrel wrench are you using? If B, even though those are designed for torquing, they don't work very well for torquing, as you may already know.

I got er done with a pipe wrench, no problem!

I have B, the nice old fashioned GI barrel wrench. Works just fine.
Link Posted: 10/17/2004 4:10:04 PM EST
I have type B as well. It torques fine. I have a selection of torque wrenches:
1/4" drive, 3/8" drive, and 1/2" drive.

For 40 ft-lb I used the 1/2" drive plus the GI wrench.

It worked fine on my Bushmaster barrel. How did you slip and take out the barrel nut lugs??? That doesn't make any sense.

heres some pics of the finished rifle...well kinda finished, I still need a scope, grip...etc...etc

Thanks for the help!

Yea, I had to remove it with a pipe wrench.
Link Posted: 10/17/2004 5:48:00 PM EST
Pipe wrench on the barrel? Instead of a vice? Could you elaborate how you used a pipe wrench?
Link Posted: 10/17/2004 5:56:07 PM EST
He killed the teeth on his barrel nut, so he had to use a pipe wrench. I like channel locks for extreme situations.

The FIRSH includes a replacement barrel nut.

"In the case of a wiped out barrel nut, a pipe wrench is an approved alternate tool for the standard barrel nut wrench."

Looks nice. At least you didn't FUBAR anything that needed to be reused.

Oh, and nice leather belt sling on your gun, too

Thanks N_A_L.

Sorry gaspain. I just went back and reread the whole post. Some how I missed that part the first time.
