Hey I have a Marlin 30a that I have messed with on and off for the last two deer seasons I have wanted to hunt with it but It has always shot insanely high the stock rear sight shot a foot and a half high at 50 yards so I installed a wgrs-336 peep in the rear scope mount holes and it shot about a foot high with the rear sight maxed out as low as it will go, so I added a taller .650 skinner front blade sight and it now shoots about 10 inches high at 50 I have no Idea what to do now except get a .750 front or a side receiver mounted peep. I am anti optics on my lever guns so that's not an option. Many of you folks are much more knowledgeable than me so what do I do now?

Sounds like you aren't focused on the front sight or raising your head to see where you hit.

Does it shoot high when someone else shoots it?

A friend of mine has one that shoots just like the abovementioned rifle he's looking for a rear peep site for his now .
I hope both of you can figure it out !

I had that problem with my flintlock. I kept switching to ever taller front sights until I got point of impact down where I wanted it.

if it is high and consistent , taller front sight

you went taller front but you also went a little taller back at the same time adding a peep

I love a good peep
even Skinner says right on their page there is no standard front sight height you go high and trim it down with a file then use the blue they sell to darken it so it doesn't shine

it is best if you can bring a vice with a padded jaw to the range shoot a group , take some file cuts measure how far you took with a caliper , then shoot a group

do this with the rear sight about in the middle so you can adjust a little later.

cut that front sight till your group is right at 25 yards that generally is about right with a 30-30 and irons should put you about an inch high at 50, 75 and and zero again at 100

if I am shooting a 1 inch square with irons at 25 yards I want to hold the bottom edge of the square to the top edge of my front sight and land them in the square
that should put you looking very good to about 125-150yard which takes care of most shots on game

I like it just a little high so that I am looking at the impact spot say you want to smoke a squirrel (with appropriate license) that has chattered at you all day , set it's head on the post and smoke away at 25 yards.

fine tune however you like , just where I would try and be

for targets try a 1 inch square at 25 , 2 at 50 and 4 and 75 you might want to go 8 at 100 then you hold the middle if you find that too small 2,4,6,8 or 10 at 100yards

the new muzzle loaders I got the opposite I started shooting low at 25 yards got out the file and cut till I was where I wanted to be
all 3 of them had plain brass front sights so it was easy cutting with a fine file

I use the chain saw raker flat file

Put a scope on it and never look back
Sell it if you can’t hit with it it’s useless to you as a hunting rifle

put whichever rear sight you like best on. buy that taller front sight. somebody put a file on the original most likely

Is it a Remington manufacturered Marlin? Marlin or rugar Marlin? I'm curious.. taller front sight should get you.

Glenfield marlin 30a made in 1977

I had a 308 years ago that would never shoot consistently; I sold it. I found that was by far the best solution.

Glenfield was the budget build Marlin what many refer to as JM/pre-remlin

they had plain maple stocks typically may have a lower polish blue stores like sears , Kmart , Pamada

the parts are Marin 336 stocks and trim may vary but metal parts the same
