I took the clamp off of my 4 month old carbine and the barrel fell out

Guess they have loosened up the specs, and it shoots like it. Dave

I'll bet it was also verrrrrry easy to put together at the factory.

nice, I used this method (from this post) several years ago, when installing my tac-sol bull barrel. now I need to get that tight fit barrel out, and install my new gemtech mist barrel. search for this thread for several hours.

WHY ISN'T THIS A STICKY?!

Physics one 0 one. Don't know how many times I get surprised by something I should already know. Good idea man thanks for sharing.

removal & reinstall ...

i realize this thread is old but figure it may be the right place to ask this question ...

i have a Ruger receiver with a Volqu. CF tensioned bbl in it. upon install it was a 'heavy' press fit (dead blow, anti seize & a lil heat on the receiver). I now want to remove this bbl to use in another build and put a different aftermarket (iron sight) bbl in the same receiver.

can anyone share experience.
-how much plastic vs elastic deformation may i expect in the receiver from the first press fit?
-with a second bbl (aftermarket tenon size) press in again or is the hole baggy??

my only comparable experience is pressing bearings in aluminum wheels and cases and you get a few press fits before it becomes 'baggy'...

thoughts??

Have you considered using a heat gun on the receiver to gently heat it and expand the aluminum receiver? That's always been my method when installing tight barrels, plus a little anti seize on the stub....

The info below is from a prior post. Because you have a CF barrel, I would avoid the oven and apply directed heat with a heat gun and diffuser.

Quote:
Barrel Installation/Removal
I own 3 Kidd builds that all required heat/freezer to install, and have built several others that required thermal persuasion.
I freeze the barrel overnight, and bake the receiver at 250-275F.
They slip together easily. If you don't get the extractor lined up just right, no worries. Just heat the counterbore part of the receiver with a hair dryer or heat gun with a diffuser until you can twist the barrel. It also doesn't hurt to blow compressed air in the chamber to keep the barrel cool and prevent it from expanding. I install the barrel in a well lit area, with the receiver locked in a padded vise, upside down with the bolt in the receiver without the charging assembly-making alignment of the extractor hook easier.

To remove a barrel that has been assembled this way, freeze the barreled action overnight, then heat the receiver around the barrel stub/counterbore with a hair dryer or heat gun with a diffuser.

For stubborn barrels, I bake the barreled action at 250-275 for 30-60 minutes.
I figured out that using a can of computer "Dust Off" and insert a spray straw into the chamber. It's liquid CO2 and will cool things rapidly.
Cover the breech face with a rag to prevent blowback from hitting the inside of the receiver.

Give it a blast or two with the can held UPSIDE DOWN.
Cools and shrinks the barrel stub rapidly from the inside out
I've never had to use a barrel pusher or any type of impact technique using the methods I just described.

I developed this technique from working on cars and motorcycles. Stuck bolts and bleeder valves on brake calipers come loose easily with this method- heat the entire area, with the fastener, then rapidly cool the fastener to shrink it.

I then later applied it to barrels and receivers.

The locked-in, tight fit you get is stable and good for accuracy.
Also- apply anti-seize to the barrel stub before assembly, it makes rotating and removing the barrel MUCH easier.

Respectfully,

DrGunner
