What did you do at the range lately?

[Musashi]

That is a nice run you put together at the match.
I spent part of my Saturday teaching kids firearm safety and basics at our range. All in all a very fulfilling class.

wha? how is this possible? is the barrel not free floated?

that's pretty weird, man.

Viper PST is how it happens, they are somewhat known to be sensitive to torque on the rings, ring alignment, and other things like that. Then consider that if the scope was zeroed before putting the caps on, then putting it on slightly torquing on the scope, throws it off. (don't know if zeroing was done before the caps or not)

Great scopes for the money, and I'm not trying to bag on them (I own 2 of them) but this issue is known and Vortex will tell you that certain ring companies that tell you to torque the snot out of their rings will/can cause issues.

Curious what rings you're running? I have a PST coming this week and an XLR on order. Haven't bought ring yet and would like to avoid similar issue.

I'm not running an XLR currently (going to be running a Carbon on my next build) I'm just familiar with Zach's rig. On my 2 PST's (both on AR's ) I'm running a Larue and a Burris PEPR. Biggest thing is not to go crazy on the torque (there's a select couple of very high end ring mfg's that recommend extremely high torque).

If you go by Kyles reccomendations on his webpage about ring selection, you should be able to avoid getting into this position as far as height goes. http://www.xlrindustries.com/Technical.html

Err to the high side by a bit, and then go with a good set of rings and a good 1 piece base and you'll have no problems. Nice thing about the XLR and other Chassis systems is the adjustable cheek piece, if you end up a little on the high side, it's not a big deal. I'd guess you'd be just fine with med or high rings on top of a NF or similar 20moa base.

If you haven't bought a base yet, bullets.com has a great deal running on NF bases for rem 700's and savages right now. $90 is a damn good price on them. I ordered one last night for my build in process. http://www.bullets.com/search?s=brand:nightforce

That is a good deal. I ordered the same from optics planet and it was $116. I'll head over to XLR site for tips.

Man that looks like fun. I haven't had enough trigger time lately to think that I'd be good at it. But, I think it's time to get off my azz and get to a match.

That's the spirit. PM me and we can try to get a member squad going at a local match.

Its the Warne tactical steel high rings on a one piece 20 MOA base. The cap was on when I torqued it down to 25 in/lbs. It was not the equipment. I just goofed up and overlooked a critical step. All is well now. It was shooting 1/2 MOA with factory Hornady match ammo. Thanks for fielding questions XC700116niner!

Ahhh that'll do it too hahahaha.

I'm bummed I couldn't get away today but yesterday was beautiful. I've had a bunch of project guns sitting in the basement all winter just waiting for a good day to take them out, so Friday was full-auto Friday for me. Had a blast shooting off several of my conversions. My new MP5SD clone has quickly jumped into my top 5 guns of all time to shoot, for just blasting away anyway. Almost no rise, and nicely quiet using just cheap WWB 9mm. Felt good to get out to the range after it's been so cold lately.

Took two of my girls to the range. Shot some pistol, then moved to the 308. The 16 year old daughter won Starbucks by beating me 😀. Very happy losing to her .74 inch five shot group at 100.

Had some troubles with the newest ar, but the boys at trigger time did some complimentary troubleshooting and after some light gas tube sanding it's running nicely now.
