As the title states, if I buy an ARMS-18 and want to put my Sightron SIII 10x42 on my M305, what height / size QD rings should I buy (ex: the ARMS-22 rings)?

On a side note, what's with the occasional reports of FTEs with the ARMS-18? I've read that some people need to make minor modifications.
 
The ARMS-22 medium rings I have clear the rear sights however my scope 2.5-10x44 is too large for the medium rings so I will hopefully be putting on a x32 scope on it and it should clear.

As for the FTE's I believe it is due to either the ejector or extractor springs. I replaced mine with the Wolfe springs and so far it seems to be working properly.
 
You cannot use the iron sights with arms 22 medium rings and a 2.5-10x44 Vortex Viper PST using the ARMS 18 mount. You can still use the scope just not the iron sights.
 
Arms 18 mount ,Arms 22 low QD rings , Bushnell tactical 10x . When I first got the mount I ran about 50 rounds or so with with just the scope mount (no scope or rings mounted ). I had no FTE,s but once the scope and rings were added I started getting FTE,s .I bought a bolt disassembly tool and cut a few coils off of the extractor and ejector springs and this seems to have fixed it.
Also took more of 45ACP,s advice and removed the c clip on the the side mounting bolt of the ARMS 18 before installing the mount.
Great mounting system but it may need a bit of tweaking . I was able to retain my rear sights when its mounted .

How's the Archangel stock working for you???
 
Nice Ergonomics but it isn't a JAE ... I think for the money its a good deal and I like mine.
There is some stock inletting that needs to be done to get them to fit right but its an easy fix .
 
has your accuracy improved much? As i currently have a USGI stock on mine and am not sure if it will be worth the upgrade?

If you are just after an improvement in accuracy I would suggest spending the big bucks and get a JAE . The accuracy improved a little and the ergonomics improved alot.
 
I had a USGI fiberglass on it before which weighed aprox 39 oz or so and the new stock weighs 4.2 lbs according to their website ...so I gained a couple pounds. The balance of the rifle feels good though. I have a couple of these rifles so I don't hunt with this one ....its just for the rifle range .
 
So ARMS-18 and medium height ARMS-22 rings should be a safe way to go?

I want the QD rings so I can switch between the scope and irons depending on what I'm in the mood for on the range or if I take it hunting.
 
I used low rings on my bushnell 10x....40 mm objective lens. If you look at the pics I provided it shows a bit of a gap between the scope and front handguard even with the butler creeek lens cap installed. ..so a low set MAY work for ya.
 
It's the rear objective clearing the rear sight that I was a little worried about. It's hard to see in the picture, how much room is there?
 
What about the Leopold QRW detachable rings or the Warne Maxima detachable rings? They are both almost half the price of the ARMS-22 rings. Anyone have any experience with them?
 
I took a fast look at my mount and there is almost 1/2 inch gap between the rear sight and the rear tube on my scope , the bell part of the scope sits behind the aperature.I couldnt take pics last night and will do it tommorow when I get home.
