Mounting a Volquartsen Barrel

The barrel shanks on the Volquartsen barrels are slightly oversized, on purpose, for that tight fit. Volquartsen feels that this tight fit aids accuracy.

Heres the way we get Volquartsen barrels in to 10/22 receivers (anybody's receivers).

1) Remove trigger guard assembly and bolt from receiver.

2) Lube the barrel shank and receiver ring where the barrel goes in with gun oil.

3) Put the barrel in a padded vise with the barrel scope mount holes straight up at 12:00 and leave enough of the barrel shank exposed so the receiver can go on. If the barrel is a THM barrel, make sure that the vise jaws are on the stainless steel portion (the part the drilled and tapped) of the barrel, otherwise you could crush the carbon fiber or Alum. sleeve.

4) Twist the receiver on by hand as far as it will go (usually halfway), making sure that the receiver scope mount holes are inline with the barrel scope mount holes

5) Use a deadman/dead blow mallet (I believe ours is an 18oz rubber head) to tap the receiver the rest of the way on the barrel by hitting it on the flat backside of the receiver. Usually 5-6 light to medium taps will do it. While tapping the receiver onto the barrel, after each tap, make sure the scope mount holes on the receiver and barrel remain aligned. If the alignment should change while putting the receiver on the barrel, turn the receiver by tapping lightly on the receiver, low and in front of where the magazine would be, to move the receiver one way or the other until the scope mount holes are aligned again.

6) Insert the bolt into the receiver and make sure that the extractor enters the extractor notch in the barrel cleanly. If the barrel and receiver scope mount holes are aligned, there should be no problem in getting the extractor to enter the extractor notch cleanly.

7) Insert the V-block and tighten up the V-block

Think of this approach as putting the receiver on the barrel rather than putting the barrel into the receiver. Tapping the barrel into the receiver could damage the muzzle of the barrel or the comp, if the barrel has one.
