Hey CGN,

As I have said in a few other threads/posts I am the proud and happy owner of a nice M1A with a NM Barrel and sights.

Now I am working on the journey of scoping it out.

Up front I will say I do NOT want remove the rear irons to do so and would very much like to be able to still use them when there is no scope mounted, plan on getting and using a scope with solid QD mounts to achieve this.

---

First choice for me is the A.R.M.S. 18 (one piece) mount.

I like that I can get this for about $300 CDN all in and that it looks quite good on the rifle as well as being very low. As well as keeping the irons useful when no scope is mounted like I said above.

Possible issues I have researched are...

FIT...that not all Springfield M1 receivers are the same/to exact mil spec and sometimes it requires some fitting ie. filling of the mount and/or gun to have it sit flush and square to the bore. Doing this is something I do NOT want to do nor trust my skill and ability to do so.

I have also read getting 100% ejection/brass clearance with the one piece mount isn't always perfect, it seems easy enough to fix/adjust this by trimming coils off the ejector? I would have to read more into this to know for sure tho.

Lastly this is one I have not been able to confirm or deny but when the mount is locked into the place are you able to take out and remove the bolt? I know you do not need to remove it very often and you can wipe it off and re-lube it fairly easily when its still in the gun but knowing so would be nice.




The second choice I have looked into is the Sadlak Industries "Airborune" mount.

I have read almost universal praise for this one...the only "bad" being that it will cost me close to $500 CDN all in.

I have also read that there is still sometimes fit issues using one of these but it seems much much more rare and might be more so for Chinese made receivers?

The other "issue" is the height of this mount, it still allows use of the irons but getting a cheek piece of some sort is almost a must for this one.

---

Which one would/do you use and why?

Any tips, tricks or advice?

Many thanks!

Bassett mounts are economic and work great.I prefer the low mount. No alteration of rifle needed. Rock solid after 5 years of use.
 
For both mounts you're looking at, fitment is a non-issue. I've had my ARMS #18 installed for a year and a bit and 5000+ rounds, and haven't seen any wiggle or necessity to change.

They both also allow the use of irons after being installed. However the ARMS is low enough that you're literally looking over it, so a scope gets in the way. The Sadlak mount has a channel cut into it so with a scope mounted you can still use your irons.

Really the decision for me was profile. I prefer things low, so the ARMS #18 was clearly my winner. The ejection issues you mentioned with it come from it being so low, but even then the only times I ever had an issue were when I was using a bulky scope ring and it pinched the brass against the op rod.

Whichever you pick, make sure you follow up with good rings aswell so your scope doesn't take a beating.
 
I like my smith Enterprize mount , it's been solid for 2 years only about 300 shots though . No ejection or alignment problems here. Use the instructions and lock tight for mounting
It seems similar to the ARMS and sadlak . I think it's all about the dovetail / reciever set screw and side mount with the proper materials and quality hardwear

BTW - I've had mine off and on with pretty good return to zero

Cheek piece needed , I got mine from "coyote ? " he's in bc and makes to order - height etc reasonable and good

On that note I haven't heard good things about any of the mounts that were made out of aluminum, usually they ended up cracking or wearing loose from use. When in doubt, get a steel mount.
 
The ARMS 18 is great. Mine is solid and has been through 3000 or so rounds. I did trim the ejector spring so it would run reliably (pre-emptively). Make sure you loctite it and I suggest talking to Tactical Teacher about his replacement for the front set screw. With ARMS 22 rings, it's easy to pop your scope off and shoot with the irons and the rings return to zero quite well.
 
x2 on the Arms 22 throw rings and Arms 18 mount. The bolt will still come out with the scope attached and I had to trim a couple coils off the 2 springs .
I have a bolt disassembly tool so no biggie. Great mount and rings combo with the Bushnell 10X scope as well .
I followed 45 ACP,s advice and removed the c clip on the side mounting bolt on the Arms 18 before installing it .
You didn't say what type of stock you want to use .Depending on the intended use and personal preference I suggest a good USGI fiberglass with the applicable mods and a tacpro cheekrest .

I hav the sadlak aluminum on my norinco, no adjustement were needed it fitted on the first try. It's nice but sometime my casing get stuck on the op rod because my ejection pattern is too foward and it hits the mount at the wrong place. It gets worse as the rifle gets dirty.
 
Here's an example of how well the ARMS 22 rings hold zero. I last checked zero on my M14 in October (I've been really concentrating on shooting my bolt guns). I took the scope off the M14 a couple days ago to put on my backup bolt gun to adjust the cheek riser height then put the scope back on the M14. This is the 1st 5 rounds through it yesterday when checking zero:

I forgot how nice shooting my M14 is, gonna take it out with me to my long range spot next time and run her out to 940 yards :)
 
+ 1 for Basset. A nice solid scope mount, very very easy to take on or off, and you don't have to remove the rear sights or stripper clip guide. They have different height settings, So if you still want to use your irons under the scope you can. I chose the lowest mount as it comes off so easily, it would be quick to go to irons if need be. The ship to Canada, and have friendly customer service.

Do you happen to know if this mount works on a M305?
