Ultradyne chassis problem

[Fjold]

I just found out about the Ultradyne Chassis and saw that they offered a left handed option for short actions. They have an eccentric plate to allow it to fit the shorter and longer action hole spacing so I ordered one for my LH Model 11.

Just received it in the mail and have an issue with it fitting my bareled action. The bolt release/cocking indicator contacts the front of the inleting. I can wedge it into the chassis but as you know the bolt release has to fall forward and down when the trigger is released so the gun won't fire.

Also none of my short action magazine (2 different factory styles) nor my blind magazine box will fit in the magwell.

Does anyone know which magazine fits their magwell? It has a rear mounted mag release.

I contacted the company and sent photos but haven't heard back from them yet.

Here's where the bolt release rubs. ( I know that I can relieve this area with a Dremel but I want to see what the manufacturer says first)



Here is how the action sits cocked in the chassis when I try to tighten down the action screws:

I can't help you with your problem, but I can tell you that I have dealt with Ultradyne CS before and they're pretty good. I have several of their sight systems.

[Fjold]

Thanks Bob, I'm still waiting to hear back from them.

It looks like it uses AICS magazines

Did you call them or email them ? I had good luck calling.

I emailed them because I included the photos

I would call them and follow up. If anything maybe they will give you a direct contact email to send the pictures to. It’s definately an issue as really no part of the action fits correctly.
They should take it back and send you another one..

Do you feel the action is cockeyed in the inletting due to the bolt release lever hitting? I guess you could remove the trigger and sear and see if the action sits in there correctly, which should mean the main issue is only the bolt lever clearance. If it still doesn’t then you would know there’s multiple inletting issues with the stock

It's definately due to the bolt release hitting the front of the action inlet. It's actually scratched the anodizing right in that spot.

I'll give them a call on Moday.

I figured out the problem. In the photo below there is a cut out on the left side of the inlet that perfectly fits where the bolt release is on a right handed Savage short action. This cutout gives enough room for the right handed bolt release to move when firing. When these guys built the program for their CNC they didn't change that cutout location to the other side of the inlet for the left handed bolt release.

[Fjold]

Well I called Ultradyne and talked to sales guy, Blake. He said that he didn't know that I had a top bolt release on my Savage when I ordered it and that they don't make actions for the top bolt release. I told him that they do because the chassis that they sent me would work perfectly for a right hand action with the top bolt release if the bolt cutout was on the right side.

I just took a 1/4" end mill and cut a slot along the front, right side of the inlet .375" long and .375" deep and the my left handed Model 11 action works perfectly. My AICS magazine will be here tomorrow so we'll see how it works after deer season ends next weekend.

The bolt release is the same for a right or left handed rifle.

I didn't know that Fred (It is Fred isn't it?) I wonder what that left side cut out in the chassis is for then. It fits perfectly for a bolt release on that side.

How do righties pull the bolt out? I hold the trigger and push the bolt release down with my right thumb and pull the bolt out with my left hand. It seems like righties could only do it with the rifle laying on a table or in a rest.

[pdog06]

We Pull the bolt the same way.
All the levers are on the right. None of the actions have anything on the left side to need the cutout that your stock has, but I agree it does look like a bolt lever cutout. I think that’s the first stock I’ve seen with a cutout on the left? guess their inletting just does it on both sides but not sure why the right side is shorter?

I've been following, and just re-read post #1. It mentions and eccentric plate, which is the washer for the
front action screw......Did you try both ways since the wrong way may cause the problem you are having ??
Unbolt it and set the barreled action in place, making sure the action lug has a proper fit. With the lug hard
against the cut out. see where the action screws need to be along with that eccentric washer......

[sharpshooter]

It's obvious to me that it's a factory screw up.

I reversed the eccentric washer and the action bolt hole will not align with the hole in the washer.

I wonder if they did a mirror image in the CAD file for the LH action.

[Robinhood]

I wonder if they did a mirror image in the CAD file for the LH action.

My thoughts also. They should put the bolt slot on the left but the release on the right.

I am concered about the rear of the action support from both sides being milled out.

[Fjold]

I talked to their customer service guy and he says that the stock is only made for a bottom bolt release action. I don't know what a bottom bolt release is (old school) so I can't see if the slot in the left side does anything.

Company has no clue what the current and relevant Savage sales are. When you buy a stock
from them, you check the box for "Savage Short Action" but nothing is there to designate what
is the release type. Company has not been around long, which makes me wonder, why make
something for that you only find in the used racks ?? Either way.....Watch their video on how to
set up a Savage to their stock. It clearly shows a flat back, bottom bolt release.

I can't speak for their chassis systems but they make really nice sights and muzzle devices.

Here's the finished project. It nailed a raccoon at 446 yards last night.
