Cons of ANO?

[FreakBaller12]

Are there con's for getting your gun annoed?
I've heard it messes up the tolerences and i don't know about that. I was wondering if i got my barrel annoed would it mess up the bore size? It's not a insert kit, just a dye ultralight barrel.

Yes, anno changes the size of the peice of metal. So does stripping anno. It's an amount that the anno shop can tell you. So you can predict what the changes will be, for the most part.

When making ULE bodies, AGD knows how thick the anno will be, so they compensate for it. Same for the body rails. :-)

[FreakBaller12]

so if i got my emag reannoed, what problems be caused?
hhow big are the changes?

[Cryer]

I talked to Tunaman and he said that in most cases, if the anno job is done right, you wont notice any ill effects.

[FreakBaller12]

what abotu the barrel bore size, how will that change, or not at all?

[FutureMagOwner]

last i checked the annoing adding and subtracting is in increments smaller than what bore size is measured with so it should be a problem (and if it does increase/decrease it would be like by 1 unit at most)

Originally posted by NeoMoses [*]Type of anodizing: You're wanting to do Type II anodizing, which allows coloring and is fairly hard. This type of layer can take color well when as thin as 0.0002" but will not be as abrasion resistant as a good 0.0008"-0.001" thick layer.

So the absolute most is changing a barrel from .689 to .690 or something. Thats even without accounting for the ano stripped off.

Not exactly true MicroMiniMe. Let's take a look at a couple of scenarios.

Case 1: The barrel currently has 0.0002" of anodized layer, and the current ID is 0.6890." You first must strip off the old anodized layer, leaving the barrel ID at 0.6894." You then re-anodize the barrel with a 0.0002" layer. In type II anodizing, generally 2/3 of the anodized layer is built up and 1/3 is below the original surface. So, your new ID is about 0.6891"... not too much of a change, really.

Case 2: The barrel currently has 0.002" (typically called a 'Hardcoat' anodize) of anodized layer, current ID is 0.6890." Stripping the barrel leaves an ID of 0.6930." The new anodized layer is Type II, 0.0002" thick, leaving a barrel ID of about 0.6927." (at least 1 size larger for a freak insert)

Case 3: Barrel currently has 0.0002" anodized layer. Re-anodized with 0.002" layer. Old ID = 0.6890 New ID ~0.6867."

Basically, it is possible to change the dimensions on a barrel by re-anodizing it. Also, I've seen very large differences in the anodizes on PB guns, (all of the above numbers are realistic) even from AGD. If you really want to have the barrel re-anodized, take it to a good anodizer who can accurately measure the coating thickness before stripping and can accurately control all of the parameters necessary to keep the ID about the same size after re-anodizing. Warning: this won't be cheap. It'll probably be cheaper to buy a new barrel.

The major problem with getting an expensive anno job on your gun is making it more attractive to thieves, a little more expensive to resolve than a barrel mismatch.

i wouldn't recommend anodizing a emag or a xmag since there is a steel metal ring in the gun that if that gets damaged you're pretty much screwed.

[FutureMagOwner]

thats why they remove the ring before anodizing the gun

[SuiciDal Sn Y p ER]

it's a big pain in the behind to remove the ring

[FutureMagOwner]

have someone else do it for you like tunaman, thats what i did

[SuiciDal Sn Y p ER]

hmm how much does he charge?

[FutureMagOwner]

i forget but for like complete disassembly of my gun (including the frame and stuff, when it came back to him he also flashed the board to 3.2 since it just came out) and shipping it to ano was like 40 bucks or something like that but you'd have to pm him about it well worth it imho
