M1 Problems Solved?.... >Guess NOT<?

[DYNOMIKE]

OOPS, plum forgot about this forum and should have put this here first..


Last couple times I had one of my M1's out it seemed a Bit OFF??
Can't describe it really as functionally it worked every trigger pull..

However working the Op-rod (Binding), Loading the En-blocks, (not releasing without a Bump) and my Groups seemed all "OFF".... Rear sight was also NOT clicking nice and solid, kinda half clicks almost mushy for lack of a better term..

Fast forward to tonight, I needed some chill (Rum & Coke) time in the Garage after my day and decided to pull the M1 out and take a Look to see if I could find anything...

I took the rear sight apart, checked everything over put it back together and noted no real change? Check receiver grooves and they are all nice and sharp, check the Little Pointy thing on the Sight and it looks perfect? Went inside my parts stash grabbed another sight assy and slapped it on.. This time things worked better with positive clicks and normal operation? This gets me thinking what I did differently with that assy so I grab a copy of my GCA magazine they sent awhile back with an article on the Rear sight assembly.. Everything on BOTH my sights appear correct and then I noted that I had tightened up the WINDAGE side screw a Little more the second time so I wonder "IF" that was the diff?
Well that was it, I assembled the original sight added a Bit of grease to the Inside (Pinion I think?) checked everything out and she is working great.. Nice solid clicks and NO movement when I extend the sight and push down firmly..
Looks like ONE prob solved and I wonder if that may help my Groups next trip?

While I have it out I decide to look into the Binding of the Op-Rod? I remove the stock, unhook the Follower rod and remove the Recoil spring from inside the Op-rod.. Spring looks kinda rough and old with some schmeg on it so I want a Better look.. Out comes the spring but damn it's SHORT?? WTF I say and look close enough to see a Shiny end on one of the Coils.. This FUCKERISBROKE I say, and whatya know the other half of the spring is still inside the Op-rod.. I fish it out, clean the inside of the Op-rod all purdy and then think OH HELL, do I have a recoil spring??
Well sumbitch not only do I have One but I find TWO!!! One New GI the other a NIW Falcon Spring... Ha I'm happy now...

I grease up the Places I remember I'm posed to grease slap her back together and she is a HAPPY M1 AGAIN...
Nice and smooth, bolt relasing so much better I "ALMOST" Gave myself an M1 Thumb working the action.. NOW I can't wait to try some of the GREEK and my Handloads again in this baby, hope I can go this weekend if not sooner...

Soooo in Closing is there any chance that the Broken Recoild spring cpuld affect "ACCURACY"? Not making excuses just wundrin is all...
I am also surprised that the Gun functioned with the broke spring, says a LOT for the Gun ifya ask me...

Ya' the broke spring causes a delay in cycling and as a result the pressures/harmonics kinda go weird. I had the same thing happen and after putting in a new spring on one of mine, it seemed like a whole different rifle. The recoil was smoother and it didn't jump around and darn it grouped good!

O.K So yesterday I take this rifle along on my Range trip with some Greek, a bit of L/C and some of my 4064 168 Gr bullet H/loads...

Shooting a 25 Meter M16 Sight in target @ 50 yds I'm in the Black in three shots and a Couple Quick sight adj... SWEET I say..

After 5 En-blocks function is Perfect, I'm shooting the Best groups I have shot with this gun and I'm HAPPY (briefly)....
Then inexplicably the LEFT Side screw is loose and my Sight Adj is now in the Toilet again... :(

Damn, this sux I don't know what I'm missing I really though I had the sight thing nailed and my first groups were awesome...
My Initial sight set-up was really close, I had good solid CLICKS and not a Bit of Wiggle when the sight was fully extended (elevation)....

Looks like I need a GOOD Tutorial on sight assembly and then another on Battle sight adjustment.. Any help would be greatly appreciated as I want to get this thing dialed in @ 50 yards FIRST so I can move out to 100 and then 200 from there..

FWIW from what I can tell ALL the parts are in very good condition, I missing something in assy I think???
BTW I have TWO other M1's NEITHER of which give me any problems like this...

TIA for ANY and ALL help....

First off, what type rear sight do you have? Is it the 'new' T105E1 M14-style rear sight, or the WWII lock bar style? Assuming that you have the 'new' M14 style rear sight, after you thread the elevation pinion into the windage knob, you must tighten the inner nut on the windage knob to retain tension on the elevation pinion. Tighten it to where you can still turn the windage knob by hand, but with firm pressure. This should be right at the point where you can't force the fully elevated aperture downwards with thumb pressure.

Clear as mud? It's easier to demonstrate than it is to explain. Once you get past this, go here for sight adjustment:

I have Lock Bars on my Other two but this one is Not and I would say Yes it is the M14 style..
