Accuracy International Picture Thread

I wanted to lighten up an AT-X and shoot it in some prone matches, slung up. The 24 and 26 inch Medium Palma barrels I got from PVA seem to work well enough. The rifle is still right at 14 pounds with a Vortex Golden Eagle on it, but it is fine in position.

The joy of the Barrel QuickLoc Clamp Screw is you can change barrels in a few minutes. If one profile seems lacking, moving on is easy.

I would not hesitate to go with an even lighter profile and shorter length if I were trying to get rid of weight.

I still have a bunch of 22-250 brass and dies to reload it, but, I'd pass on getting a 22-250 barrel for my own AT-X because I don't want to have to learn about feeding that case through the magazine.

I suppose the $100 tripod could collapse any moment from the alleged bank vault sitting on top of it as well. What was I even thinking buying AI’s again.
Haha 😁

I’m serious though. Those first gen bar clamps were dropping like flies just fyi. I run the next gen on my AI’s. Have spurh on both of them one being a ZCO 527 and the other a NF ATACR 735.

The NF mount cracked and was replaced. The bar on that one was the second gen which is the same as the mount you bought from px. Replacement has been good. But keep an eye on it. Especially with a tank of a scope if the Gen III is as heavy as earlier models
 
Appreciate the heads up. I had not heard that.
I won’t crowd this thread with spuhr posts but research it if you want. The thicker mounts aren’t as bad. But the flat bars had major issues. My NF mount has the same 4 screw clamp as that fde one you bought. My ZCO is a 5 screw clamp which hasn’t had issues

why not just do a #3 or similar light profile
Well, it’s just current barrel availability, plus I want it threaded 5/8-24 so it becomes harder to do that the lighter the contour. The barrels I’ve found in stock are either a #5 or a m24.

Anyway, can anyone compare a #5 contour to either the 2018 contour AI barrel or the lighter AI contour? Man, I wish barrel manufacturers just posted a pic of their contours or something.
 
Is it just me or were these around $750 a few months ago? It's like the Ai stuff is going into orbit!

$1,000 for a new AiSa bolt.

Same with Sako, a trg bipod is now 780 Euros. Magazine in 338 is 270 Euros...i know because i bought both last week. Got a good discount, still paid almost 1000 Euros for both. Thats just insane.

The Sako TRG bipod has always been expensive but I remember when it was in the $400 range then shot up to $500ish and stayed there for years.

Wanted to run a barrel contour question by you guys. Anyone ever put a #5 contour on their AI?

Background:
This will be a coyote and pdog barrel (22-250, I don’t reload), so with coyotes that means a bit of walking. I could go with a lighter #5 contour or a M24/M40. Going 20”-ish, so not sure how much weight I’d save at that length.

@Frank Green implies the M24/M40 is either identical or quite close to the current so-called “2018” contour. I might be reading too much into his statement.

But I don’t have a feel for the #5. Never seen one, or if I did I didn’t know it at the time.

I do know that the 20” factory 308 that came on the rifle definitely has a slimmer contour than the 6br prefit I bought from Mile High.

Thanks for your help.
I think your talking about the 6518 contour. Has a really short breech length and then a quick taper down to like .900" diameter and it's .900" at the muzzle correct?

That contour would be lighter than a M40 contour.

Not sure what/who's #5 contour you are talking about.

A Remington varmint contour vs the AW contour as in the pic below... weight wise about a wash.

I've got multiple AI "2018" barrels and M24s. I can do a SxS bit of measuring for you if need. Weight will be an apples to oranges unfortunately because my only M24 tube off of a rifle right at the moment is 3" longer than my AI barrel that is also sitting off a rifle.

rough number.... a piece of material .900" in diameter x 1" long will weigh approx. .183#. Take 3" off and your looking at about a .5# of weight on the barrel + or - depending if your taking the length off or adding the length to the barrel.

I traded AXSR barrels with a member on here, and the tenon appears to be damaged. Would this need to be repaired on a lathe before attempting to fix the barrel to the receiver? Is the whole thing trashed?

I would think someone who chambers barrels can fix it. Will it ever be right, probably not, however I would think after smoothing that out you would never notice a difference had you not known about the damage beforehand. This might sound caveman, but to be honest you could probably do it yourself with some patience and a little time..

If it was any other rifle I’d be right there with you, but not this one.

Were you made aware of this damage prior to the trade?
I looked at the photos I received prior to the trade and believe it possibly occurred in shipping. However the box does not appear damaged. At this time I don’t believe anything nefarious has happened on the other party’s end.

Edited to include photo.

I'm going to be the odd ball out here i believe but I'd take a fine hand file to it and just knock down any proud protrusion. That's a non critical part of the barrel and the bolt face should be inside that outer part and not touching it.

If it was mine I'd contact the seller and see if I can get some cash if you are really upset about it (I wouldn't blame you if it was undisclosed) but in the end I'd do it myself like I said above. Just go slow and only knock off the proud parts and smooth it out.

Yea..sucks it looks like shipping did it. I have a guy about 30 miles from me that i have chamber a lot of barrels that i would take it to.

I always use a hard plastic cap on the end so this cant happen.
Hope it works out for you and you aren't screwed.

Based on that one photo it doesn't appear to be damaged at that point.
