10/22 V-Block Question

Hi guys, I recently upgraded the barrel and receiver on my 10/22. Its the DLASK silver receiver and a Green Mountain stainless sporter barrel. While installing my new barrel into the new receiver, I was careful to center the extractor claw with the groove in the barrel. The barrel's fit into the receiver was incredibly tight and it took me many hours to finally squeeze the barrel in. I Heated the receiver and froze the barrel (as many have recommended) and still had to use a vice and rubber mallet. Once I finally got them together and had the extractor aligned perfectly, the notch in the barrel for the V-Block was crooked. Because of the incredibly tight fit, it will be very difficult to rotate it again. So here is my question: Since the extractor is vital to the reliability of my rifle, should I leave it where it is and leave the V-Block crooked? Or should I attempt to level my V-Block and maybe the extractor will still be aligned correctly as well? Is there anything wrong with having a crooked V-Block? I certainly don't want to damage anything and I'm a bit of a perfectionist so I'd hate to sacrifice any accuracy by leaving it like this. Not to mention the time it would take for me to re-center the extraction claw if i tapped the receiver level with the V-Block groove and it didn't work out. I'm thinking Green Mountain's tolerances must be more accurate than my naked eye though so leveling the V-Block groove must still keep the extractor lined up, no? Just looking for your guys advice before I commit one way or the other. Sorry for the long message and repeating myself a few times, and thanks in advance for your opinions on this.

Anyone? It's cycling through dummy rounds great and the claw is ejecting them every time, but I'm still wondering if the crooked V-Block will do any harm before I shoot it.
 
Wow, didn't the instructions tell you to sand the barrel? Most aftermarket barrel tell you to! Dlask, tactical solutions for sure do.
I wonder if you haven't damaged either the barrel or receiver? I'm guessing if you sand the barrel to fit, you won't have any v-block issues!

I'm very happy about the tight fit, that's not the issue here. The problem that I'm having is that with the extractor centered where it should be, the slot in the barrel for the v-block is not level (it is rotated a few degrees). The tight fit only comes into the question because any adjustments become very difficult and time consuming. However, with the cleaning hole in the rear of this receiver, I will have no reason to remove the barrel after I have it where I want it.
 
If the v-block is not centred you may be torqing the barrel off centre. I would suggest setting it up so the v-block fit properly and then see if the extractor functions properly
 
Sanding the barrel would make insertion easier, but obviously won't affect the position of the V-block, unless you sand so much off that tightening the block forces the barrel to rotate into position. I wouldn't want it that loose.

The first aftermarket barrel I used was a Green Mountain, and it displayed the exact condition you're describing. With the extractor perfectly centred in the slot, the dovetail was a wee bit off bottom dead center. I fretted a bit about it, and then just slapped on the V-block, torqued it as suggested, and shot the gun. No problems, accuracy was significantly improved over the stock barrel, and all was well for about 1200 rounds. Then, while working on the gun with the stock off one day, the %&$# thing was just bugging me so I went to the trouble to correct the V-block groove to center. The extractor still worked perfectly after that, and accuracy remained the same. If your dovetail/extractor discrepancy is too large, this might cause problems, but for a tiny bit I'd try it and see. Good luck and I hope you post your results.

I never noticed this problem with several other aftermarket barrels of various types that I played with.

Thanks for your reply! I breathe a little easier knowing I'm not the only one to experience this. Sounds like you went through the same thought process as I am too. I really want the extractor to be centered but having the dovetail off center is just bugging me, even if its not hurting anything. If you had success lining up the dovetail for the v-block without effecting the reliability of the extractor, I'll probably go to work on doing the same. I'll post my results when I get the chance to work on it some more or take it to the range. Thanks again.
 
If the V-block is slightly misaligned.... no big deal. The extractor is what is needed aligned more.
Just make sure you don't overtightened the V-block bolts when you put it back together.
 
I've just gone through the same thing and with a Green Mountain barrel. I also opted for best extractor alignment.
Maybe it's a Green Mountain thing. For some reason Kidd don't recommend their V blocks for use with GM barrels.
I ground the bottom surface of the V block a bit to keep it flush with the action screw block.
 
Okay, so that's three GM barrels with this quirk. Is that more than merely coincidental? My particular GM barrel shot no better than a much-less-expensive Butler Creek replacement, and it didn't match the accuracy I got out of two different Dlask barrels, which as I recall were roughly the same price or perhaps even a bit cheaper.

Just out of curiosity, do you guys recall which direction the barrel was offset? Mine was rotated slightly counterclockwise, when viewed from the muzzle end.
 
if you really wanna know call Dlask and talk to Joseph.
ive had many long talk with him about his receivers and barrels when i was running into problems.
in fact he will usually install the barrel for you in you are purchasing a receiver or barrel from him (if you ask nice).

but if you are worried about it call and talk to him, its his receiver he will tell you exactly what is ok and not ok.
but with the snug fit of your barrel i wouldn't be worried about it.
 
Alright guys, thanks again for the feedback. I finally managed a trip to the range to test fire her today so here's the update: I installed a Tactical Solutions aftermarket V-Block for peace of mind and made sure to torque my new V-Block as recommended. I felt comfortable giving this a try. I really did want to leave the extractor as centered as possible. I'm happy to report that everything went great. I only had time to shoot 200 rounds while sighting it in, but all 200 rounds cycled flawlessly. I spent most of my time sighting it in, but I did shoot a nice 0.750" group at 50 yards before I had to leave. Oh yeah, that was with the cheap federal hollow points I bought in bulk a while back. I look forward to my next trip to the range and trying out some better ammo. I think I'll leave the barrel the way it is with the extractor aligned properly. The accuracy improvement was noticed immediately, despite the V-Block being slightly crooked. Thanks again for the input!
