Good Ol' west
I just got a new walnut stock from Springfield Armory and a NM sight kit for my Norc. I also had all new springs thrown in as well as a Badger Ordanance op rod guide put in. Currently I'm shooting some South African surplus ammo. I believe it was 155gr ball ammo or something close in weight.

Since getting all the new parts its seems accuracy has gone down the pooper, contrary to what I would have expected. Thinking of buying a couple boxes of various new factory ammo and see what it does with decent ammo. Perhaps the new springs and such don't like the surplus ammo quite as well as the old springs and stock did?

Keep in mind I may just suck at shooting with irons but I didn't think I was that bad. Anyone have any other ideas as to what could be causing this?
 
How is the fit of the stock? Is it binding anywhere or is the stock ferrule pushing up on the gas assembly? Was the trigger assembly really easy to snap closed?
 
Ya the trigger assembly is actually pretty tough to snap shut, really tough to open more than to shut, probably some difference in the metric vs imperial manufacturing. The sights were install by Rick at Alta Tactical in Calgary. He does some top notch work. The stock probably needs so bedding though, there no pressure on any of the gas system though, just a little by the receiver, not super flush and a real tight fit.

As far as the groups go, its so inconsistent its not even worth noting. We're talking 12" or greater groups at 100yards. Probably going out to the range with some good match ammo and see what we get with that. If its good sub 3" or 2" with that at 100yrds I'll leave it as is, if its still garbage I guess its bedding time.
 
Time for you to have another look at my DVD (really a 2 CD-R set) of the M14 Abbotsford 2004 clinic and see what you need to tighten up.

I'm certain there is something we can tighten up on that boomstick. Nothing that you mentioned raises alarm bells....

Okay, a couple of tests that I teach in my clinic....

* Ensure your boomstick is unloaded and cleared (that's yer job to do)
* Hold yer op rod to the rear... hold it... hold it...
* Now with a very alert ear... release the bolt and listen for the Piiinnng sound the racked action makes.
* Is you PING test loud ? Is it long ? (likely not long)

* The volume and length of the ping will indicate how tight your gas cylinder assy and moving parts are in tune with each other. :D

Now, the KLIK test!!

* Disassemble the M14, pull the barreled action out of the stock.
* Pull off the op rod and bolt (you know how to do this , I'm assuming.... :rolleyes: )
* Now stand the rear receiver tang on the table top and with 2 fingers, jockey the op rod guide sideways and listend for ANY kliking sound.

* This loose or tight op rod guide will greatly affect your accuracy. Tighter is best. Many CGNutters have RED Loctite'd this in place. Others have hammered a smaller diameter roll pin INTO the existing Kommunist Xhinese high school shop class installed roll pin. :p

Get back to us and let us know how the 2 test make out.

If the rifle shot well enough before you restocked it, why not put the barrelled action back into the original stock and give it a test with the SA ball? If the grouping is better, you will know that the problem is related to the new stock.
 
I think both of those could be problems.

I checked the stock ferrule. The tab on the front band that bends back is in contact with the ferrule, I would say a little tighter to one side that the other. Its only this bent tab that is touching, if thats a good thing or not I don't know.

And Hungry, as far as your tests go. The ping last about .5-1 second and varies in loudness depending how you have it facing you. I'm confident its not that loud though judging by some of the M14s I have heard at the range. Also the badger ordanance op rod guide I have wobbles back and forth, no clicking noise but not a tight fit.

I will also take the old stock out as well and see how that goes. Thanks for the help so far guys. I'll let you know what happens at the range.

Just got back from the range. Hornady 168gr A-max got approx 1 3/4" three shot group at 100yrds. The 150gr Federal Nosler BT shot 3 7/8" at 100yrds. The Remington 150gr Accutips shot the same as the South African 146gr ball ammo at around 8". I've never been a fan of remington ammo personally. Never owned a gun that liked it the best. Switching stock did little to the SA ball groupings. The groups were tighter than yesterdays. Put some fresh grease on it is all I changed.
 
Are you referring to a Badger Ord. op rod spring guide ? I believe Hungry is referring to the "Op Rod guide" the piece that hange off the barrel the the tube of the op rod slides in . I just want to make sure that everyone is referring to the same part . The Op rod guide should not be loose ,the spring guide should have a little play.
