Another M14 scope mount post

the KEY word here is REPEATABLE- something you don't get with an ALUMINUM mount, it doesn't matter WHO makes it- i have 4( b-sqare, s&k, 2nd generation springfield and third generation springfield- it's the expansion factor of two DIFFERENT metals that causes the rifle to lose it's zero- only the s&k can be mounted /dismounted- it's a nam era single point mount- big screw only- because it's STEEL-and you don't get that until you get up to 200 bucks- mine was on the rifle

Most rifle today has steel receiver with aluminum ring on top of that. Never heard any problem.

For a receiver mount the expansion rate won't matter since the receive is not hot.

The only reason there are 200$ mount is M14 is expensive in US so people don't mind spend 200 on a 1500 rifle.

A piece of CNCed metal for 200? Give me a break.

My 2 cents
 
I am not going to spend $200 on my 399 Norc M14. Just need a cheap mount solution. I know those steel ones are good, but according to the reviews, seems this one holds zero too. really want to give it a try!

Is that one any different than the one Canada Ammo has on sale for $39?

Fabsports has them also for about 39.00 I had one and it worked 0 issues just use loctite. You could also use a bedding compound on the side. Just use realse agent
 
Very true

Aluminium cheap mounts are not worth it...... ARMS18/Sadlack/SmithE are the only way to go !

Aluminum mounts have little trouble with heat variation from shooting as the receivers dont get very hot - only warm -

Its ambient temperature differences and stacking tolerances that make aluminum steel less desirable than steel steel.

Just curious, what do you mean "ambient temperature differences and stacking tolerances"? How that affects the mount?

Thanks.
 
All you guys are totally correct. An aluminum mount is every bit as durable and stable as a steel one. Ignore all those guys who have experience and tell you otherwise. Get that $39 bad boy on there ASAP (the Marstar is WAY overpriced!), stand back and poke it with your finger a couple of times and then snicker at all the naysayers. Put 50 rounds through it, check it for tightness, and smile.

Then check it again after a few hundred rounds and go "Hmmmm......what the....? Oh well, Loctite should fix that right up."

Then a bit later and go "Didn't this hole used to be round? Did this part always move like that? SH****T!"

Seriously. Do it. Then post results here, after several hundred rounds, not just three magfulls. Those of us who "knew better" and had to learn the hard way will feel less silly for having made those mistakes.:)

Technically, this mount is only a partial ALUMINUM mount. Out of 7 parts, only one of them are made of aluminum, all others are steel.

All three critical contact points: front set screw, rear dovetail insert and the side screw, are made of steel.

It's an interesting mount, isn't it?
 
Buy from Canada Ammo - they work - supports CGN!

I bought one of the $39.00 ones: The dovetail insert is steel and the hex-head bolt that holds it is also steel. The large "thumb-bolt" is steel but I switched it for a smaller "bolt-style" with the same thread so it doesn't catch on anything (never plan to remove the mount). I am told that if you Loctite it properly the first time and never plan to remove it, the aluminum body will be fine for a long time: by the time the threads "shake loose" as some people report, you've spent your money on ammo instead of a mount... and you get time to budget for better.

In other words I was told that the aluminum body-type with steel attachments work fine for a long time as long as any scope removal is done at the rings, not the mount.

If you are going to "mount-remove" at all (due to different shooting styles and/or competitions) you should start with an expensive one of all steel. Those are $255.00 I believe for an ARMS one at the CGN sponsor P&D Enterprises.
 
humm.....intresting.... Well thanks for all the comments guys. I will place an order on ebay ( I have a lot (FRAUD ALERT) credits) and release a review as return. I just noticed it is made by Rhino Gears, songs like a solid name :D

Using hyper tuned half to one M.O.A M14's, with aluminum mounts, I have experienced one POI when air temp. is cold, and a different POI its warm (more so than ambient temp. and ambient air pressure bullet flight affectations).

I attribute this phenomenon to temperature differences and stacking tolerances - just like the situation with Ruger 10-22 steel barrels and aluminum receivers (even though the temp. variation would be less severe than the 10-22).

Never experienced this with a complete steel mount.

I had the same problem with my heavy barrel SAKO and Tikka. Maybe because of different thermal expansion rate of aluminum scope and receiver?

Nerveless, while this mount is perfet for shooters with SA surplus ammo, or, even handloads, it shoudn't go with 5,000$ long range M14.
 
Anyone who only sees their Norinco as a $350 beater and has no plans to spend money on better parts, tuning, improving hte bedding or getting better stock sets, etc. should not buy a $200+ scope mount - I absolutely agree. In fact, most of your guys in this category will also have a cheap scope too.

If you want guaranteed reliability and ease of install that will outlast the rifle, get a Smith Ent or Sadlak STEEL mount.

If you want to spend a little less and know how pto properly fit one (it's much harder) - get an ARMS18.

The aluminum mounts are for the trash bin and cheap blasters. Have had most of them and discarded them for the junk they were.
 
I have shot all three M305 with handload. 2 of them can do 1 MOA and the other can achieve 1.3 MOA. I got 0.75 MOA once, but that’s luck.

M14 is a old rifle with several disadvantages:

1, It is a thin barrel rifle;

2, The barrel is not even free floated;

3, Fundamentally, it’s a SA, not a bolt rifle.

Those issues have much severer effect on its accuracy that thermal expansion rate of mount. By the time receiver temperature could affect the stability of the mount, its barrel has well wrapped.

M14 with alum mount can reach 1 MOA with handload. Beyond that, $$$$$ talks….
 
I'm not suggesting that the reason for avoiding the aluminum mounts has anything to do with accuracy. I'm sure the first 50 rounds shot after installation will be just as accurate as they would be if a steel mount were used. The problem is with longterm durability...screw holes get pounded out-of-round by recoil forces, aluminum deforms in weird ways, and in general the mounts just plain stop doing their job, which is to hold the scope in a solid stable fashion. I could have bought another case of 7.62 surplus with the money that I wasted on aluminum mounts of various types, let alone saving myself the frustration of trying to make them work.

But it's your money, so...
