Bedding a chassis gun

[ar15barrels]

is this not what we are talking about here or did i miss something?

receivers are straight the chassis is whats out.

Actually, the problem with most chassis is that they do not support the tang of a 700 receiver and therefore the tang gets bent as the rear action screw is tightened.
This puts the whole receiver into a slight banana shape.
As the reciever is going from straight to banana, the barrel acts as a pointer and starts deflecting because the barrel is anchored to the front of the reciever.

What kinda damage does bedding a chassis do? People mention it affects resale. Is it just cosmetic or does it screw stuff up for the next owner that wants to drop a different barrel in?

yep i get it...i had a savage PTA in a bell carlson A-5 with the aluminum block...the tang area was about .070 lower than the rest of the block.

No damage to the chassis or the reciever occurs from bedding.

Resale is effected because you need to grind out the bedding and re-do it if you want to swap receivers.
That's extra work that you would not have to do had the chassis not been bedded.

Damage COULD occur during the removal of the old bedding.
Any damage that occurred would likely just be cosmetic and would disappear under the new bedding though.

I still do not understand the fascination with chassis-style stocks. They are heavier and more expensive than traditional stocks, and like another thread has covered, STILL REQUIRE BEDDING. OP, MDT is giving you the runaround, you need to, at the very least, skim bed your action to the chassis. As AR15 Barrels said, bedding will only help your rifle (if done correctly).

Makes a bolt gun look like an AR.

I do not like chassis’s but I own/run 3 of them...there is no comparing an MPA chassis to a stock when you start looking at the features and functions...If they are to heavy for you maybe it’s time to hit the gym...my comp rifle weighs in at just under 20lbs I have no problem running stages.

[bug_eyedmonster]

Woah, easy there tough guy. What features and functions are you referring to? How do they benefit you over a more traditional stock, and why would those features and functions not be available to them?

[oktavist]

Maybe I don't understand because I just woke up and I'm still sleepy...

Aren't things suppose to move when you adjust the action screws? Is this just a solution to loose action screws? Or are you guys getting barrel deflection with proper screw torque?

Saying, "I loosened my stuff, and now it moves, so I should bed my action." Is what I'm getting from this.

Sorry, I'm slow...

He's talking about the forend rail and the weight system.

If the action fits the stock, the stock will not bend the action while torqueing the action screws.
When we talk about loosening/tightening the screws to check for movement, we are talking about testing for movement from about 1 inch-pound of torque up to max torque which would be around 35-60 inch-pounds depending on the screw head.
We are NOT talking about movement that would occur when the screw is completely loose or removed and there is no torque present.

Why the tough guy comment? Because I said if you can not carry your gun go to the gym?
This is just a few of the things an MPA chassis will do outta the box that your traditional stock will not do...can you add stuff to make it close? Maybe....but then there’s the extra cost and weight.

Also a cutaway magwell for faster reloading.

He comments about how heavy chassis stocks are. How much heavier are they compared to McMillan or Manners stocks? Those two manufacturers certainly aren't lightweight either, especially if you have adjustable buttstocks and cheek risers. Unless he's talking about plain-jane B&C or H-S stocks which can be lighter.

[smoothy8500]

Yeah, I think his comment was slightly out towards left field.
