go ahead and laugh but which way does a crush washer fit on a barrel before the flash hider. Feeling dumb as hell, vhyper |
HEY, YOU HAD MORE BALLS THAN I DID, I WAS AFRAID TO ASK. AT LEAST YOU DIDN'T DRIVE DOWN TO THE GUN STORE AND SAY "CAN I SEE THAT AR"......... |

On this general subject, are aluminum vise blocks really superior to blocks of wood in a really tight vise? I ask because I crank my wood blocks around the barrel really tightly, and it still moves when crushing a crush washer. I'm guessing there's serious friction between the AL and the steel barrel. Does AL from the blocks deposit on the barrel? I assume you clamp the barrel under the handguards to avoid any marring being visible? Thanks |
I had a phantom 5C2 that woudl not time out rigth with a crush washer...it was way loose or about 3/4 around it would not really go any farther. My local gunsmith turned a few thousanads off the back of the phantom on his lathe, blued it with some birchwood casey + propane torch (wecsog hot blueing  ) and it timed out fine. |
I'm going to have to search on your username to tag all these little pearls of wisdom. Seriously, it's appreciated.

crush washers arent made to be reusable; h/w, i guess, you could in some cases if it tuned correctly w/ the new/re-installation, unless its way flattened i'd just get another, new crush washer also, peel washers can be a PITA...damn slices are SHARP as hell--one slipped out and cut my leg (scar is still there)  narrow end towards reciever, wide end towards muzzle device's base; in all reports, it doesnt really matter.... |
I reuse them all the time. If they get too flat to index properly (top of FH on top), THEN you need to replace them. They crush a lot before they get flat. They don't crush at all if you don't have something to hold the barrel still. I use a vise and leather (tip from Randall like above from back when I first got started w/ARs) or even two blocks of soft wood in a vise to hold the front sight base. Then, the crush washers flatten out nicely and index the FH correctly with no lock-tite or anything like that needed. |
I glued a strip of inner-tube in my aluminum vise blocks. The rubber grips the bbl. and helps keep it form turning. |
Man I'm glad you asked that question. I just got a phantom in the mail today and was looking at the washer thinking "Great, now what?!?!?"
