What is the best out there? Seems alot of differing opinion.

Not worried about removing regularly and holding true - once on staying on.

Do want a very stable, mount that will excel in abusive situations. Not a safe queen, think more hunting/farm/quad/truck gun.

thx janssen
 
if you do the ARMS18, it is the lowest of the scope mounts. You'll probably have to fuss with shortening the ejector spring or else you'll have issues with empties bouncing off the mount and getting stovepiping like mine.

I've heard the same, but the two ARMS18 mounts I have had, one years ago & one now, did not cause any ejection issues.

Cheers

the best solution for M14 platofrm is M25 LRB receiver , modernized M14 ,


for M305 norinco I would go with SADLAK scope mount or Fulton scope mount ,

solid and stable M14.ca , the problem is you need a cheek rest for 3rd floor
 
Thanks - confused on the ARM@-18, see alot of poeple that like it but also alot of complaints about stovepiping brass - is this just a problem with some that have stronger ejector springs?

Don't really mind a higer aimpoint - think I will go with the CASM, has anyone used the CASM Long sight plane? does it hold true to the fron with no warping etc...? For the extra 100 seems like a nice option to have.

thx JJ
 
I have a Smith Enterprises mount, it stabilizes off the stripper clip mount, the usual side bolt and has an adjustable length screw that rides on the front of the receiver. It permits use of the iron sights at relatively close range, like 300-400 yards or less.
 
I had a problem with one of my M305's in that the receiver left side was not milled or forged perfectly true to the centreline of the bore, and the scope was pointing to the left, quite a bit. A bit of digging and reading showed that this was not all that rare. I sold the ARMS 18 and put a M14.CA mount on.

I clipped a few coils out of my ejector spring when I installed my ARMS18 and haven't had a single issue in thousands of rounds. It's a pretty easy thing to do.
 
I've had both the M14.ca CASM and the ARMS18.

The ARMS is lower and allows you to keep the rear sight in place. You do have to remove the scope and rings to use the rear sight, but not an issue with QD scope rings, which ARMS does make.

The ARMS does sit low enough that casings will bounce off of it during ejection and cause a jam. The solution, as mentioned, is to cut a couple coils off the ejector and extractor springs (exactly how many is found in the DIY thread) to lessen the force of ejection, which I had to do on both of my M305 rifles.

The CASM was okay, but you do have to lose the rear sight and it does cause the bore of the scope to ride much much higher which you will have to compensate for with a larger cheek rest.

I had originally went with the aluminum CASM but didn't the like way it flexed when tensioned too much. I suspect their all steel version would not flex as easily. My rear sight pocket was a little off axis as well so I got rid of the CASM and went with the ARMS 18 with the ARMS 22 QD low rings

I had one ARMS mount on an M305 a number of years ago and I did indeed have to remove the rear sight to get the scope mounted in a comfortable position. Removing the sight allowed the use of lower rings and let the ocular bell sit a bit more forward. I never once had an ejection problem with that set-up.

My favourite optic mount was one of the forward-rail "scout" types which replace the handguard. I believe the one I had was an Ultimak, but they are also made by Amega Ranges and M14.ca. It let me use a forward-mounted scout scope, which I like, and could also be combined with a cantilever mount which held the scope further back in the traditional position. Either way, that base clamped securely to the barrel fore and aft, and seemed to function like a strut to enhance accuracy. The gun always shot better with the scout mount in place, regardless of which way the scope was mounted. I had similar accuracy improvements on a Mini14 using an Amega Ranges mount.
