What thread pitch is the muzzle on the CA-3?
Metric or inch?
I am guessing inch, RH 5/8X24.
Could be metric, RH 15X1.
Thanks for letting me know the rifling is 1 in 10 for the M-80 NATO round.

It's Century so most likely 5/8x24 my C308 was 5/8x24.

I doubt it's metric, the new ptr's have the 5/8-24 threads and this uses a new style muzzle device so I'm betting it's 5/8-24.

Most likely, it's going to shoot Federal Gold Medal Match 168gr the best, like the majority of .308 1:10 barrels.

My PTR91 shoots it at 1.3 MOA at 100 yards.

For those wondering about the sale ive been watching these for a while before i got the parts kit build i have now, And they have been on sale for a long time. So no worries that they are sold out now, they will likely still be 869 when they come back in stonk

Good to know.

They are back in stock now. I’m undecided on if it’s worth the price though?

I think its hard to beat, But with all things century youre rolling the dice on a lemon. Seems OP is happy with theirs so id say go for it. I also think there are so many of these dont let the FOMO of the sale distract you. When i bought my M9A4 last year they were on sale for 850 at Berelli, and they are still on sale off and on now.

Thanks. This is what I was looking for. For me it was the FOMO feeling and considering I don’t know much about these I wasn’t sure if I was missing a limited opportunity. I will hold off - can get a suppressor or another handgun for that price. 🤪

With Form1 turnaround times for individuals right now i dont blame you, My last Form4 was 5 days.

 

[noob72]

are these barrels nitride or similar process?

or just 4150 with no protective finish?

 

[Mike0987]

Probably 4150 with no protective finish, barrel is parked on the outside and appears to have no finish on the inside

 

[bluezebra]

You are correct it does not have the little mount piece in front of the sight base but still has the bump outs to add a pictatinny style mount.

Those bump outs can't be used unless the underside of the bumps are ground down flat and square so the clamp mounts you use can hold on.

Mine had its sights welded on crooked, POI is 6” left at 100yards with the rear sight cranked all the way over.
Buyer Beware

Sorry to hear PTR screwed up your gun man. I'd try contacting them directly to see if they can fix it.

Atlantic has these marked down again. Currently $769. Did anyone post a range/shooting report? I'm okay with the other issues mentioned but would like some confirmation it actually cycled/works

My CA-3 CYCLES/WORKS FINE.

The claw mount bumps are not enough to attach a scope mount. The bumps are also machined to have a cut in them to interface with the feet of the claw mount. That and the absence of the proper G3 sight base is a no go for the claw mount. You may be able to attach something but your accuracy will probably suffer. It would have been better if PTR attached a picatinny rail to the top of the receiver. That's what I would do if I had a CA-3 and wanted to mount an optic on it. YMMV

I believe PTR sells a PTR91 GI model, similar to the CA-3, with and without a rail attached.

PTR91 G.I.s (model 100, no optics rail) is currently $1200 at Atlantic.

EDIT: Model 101 has a rail -

Well, I decided to pull the trigger on a CA-3 today.

I have a nice set of green German G3 furniture that has been waiting for a home. I'll most likely refinish the metal and add the nice furniture. I'm expecting it to be pretty rough overall. We'll see how it functions and shoots.

CA-3s are out there at a few places for about the same price as Atlantic (currently on sale at $770). I bought from Defense Depot in IL because I like to support gun businesses in IL - they can use it. They have a lot to deal with. They were about $10 more than Atlantic.

I've purchased from Defense Depot before, and they have been good.
