I have a very nice Korean era that I got from CMP a few years ago. I replaced the stock with a Boyd's and relieved all the rub spots and forward and rear guards. Passes the tilt test. Keeping it legal for Garand matches. Had a very fine 'smith straighten the op rod and that improved group size significantly. Very dependable.
I have to put in 19 clicks el. for a 100 yd "6" hold to hit the bull.
Any thoughts?

Thanks in advance.

That maybe is a little to much.

Measure the front sight front its base to the top pf the blade, the norm is .728
If it is much taller than that, there is the culprit.

You can also file the front sight down some to bring it to 10 -12 clicks at 100 yards.

Does it shoot low from the very first shot or start to shoot low as the barrel warms up.
Hows the lock up?
If it consistantly shoots low the front sight may be the only answer

In the meantime, inspect/verify your rear sight that the 19 clicks is really lifting the ladder that much. Push on it with your thumb as you dial it up from the bottom. Could be a loose set screw in the elevation knob.

FS measures .721.
All shots low from the first. The lockup is tight.
Yes the rear sight is lifting 19 clicks.

Maybe I'll disassemble and re-check for rub spots.

Any other thoughts?

And thanks for the replies.

Only problem I found was that the firing pin tail is impacting stock at the rear. Easy fix.
But that sure can't be the problem I wouldn't think.
Any other thoughts?
Thanks in advance.

Check on CMP forum for stock fitting but on Boyds stock another contact spot is on stock itself. The barrel doesn't fit all the way down in the stock and can cause it to shoot high. Another contact spot is in trigger guard assembly, Its in the little u shaped cutout where the trigger disengages the sears. You will be able to see this as there will be a little line going across the u shaped cutout. Just relieve it and trigger will be a lot crisper.

Does the rear handguard touch the reciever or the top of the forearm, and does the front handguard touch the the gas cylinder?

spud

Phil,
No. the rear handguard is relieved at the rear and clearanced from the forearm. The front HG is a little snug but does have fore/aft play.

Normannewguy,
Thanks. Already done.

Thanks fellas.

Still open to more suggestions.

The other thing to check on a Boyd's or Dupage stock is whether the barrel is down tight on the top of the stock's barrel channel up front. More explanation and a picture of a corrected front by Orlando here; Question on fitting a Garand Stock ferrule to a new commercial stock.

If that is not going on, just shorten the front sight blade. Many G.I. front sight blades were shortened on active duty and it is legal for a CMP games match or any type.

spud

Gus,
The stock is relieved and the bbl isn't touching the side of the forearm.

If I shorten the FS... Ea. .08" accounts for roughly 1 moa. If I knocked off enough to take it down to a 10 click for 100, I wouldn't have much FS left. But at least I know it would still be "legal". Ha!
One thing I did note though was that my rear sight is very tight w/ a LOT of el. dialed in.
So how many clicks up from 100 yd 0 do I need for 600 yds? Maybe I can get by anyway.
Thanks for the reply. I appreciate the help.

.008" is 1moa..... not .080"

spud

Thanks for that. I obviously misread some info.

use a flash light to check for clearance. IF you see the light through then your good to go.

spud

If you mean just forward of the rear of the receiver then yes I have ensured there is clearance there.
Thanks.
