Marlin 336 sight adjustment. need help
 

How can i go about adjusting the front sight? I hope not to have to buy a $150 sight puller, but i can't really move it. My gun is shooting about 8" left at 25 yards.

any good ways to accomplish this? i do like the stock sights but would be open to a replacement set (front and rear) that could be adjusted much easier..

Typically the windage (left to right) adjustment is made at the rear sight. Move the rear sight to the right. I'm guessing it is mounted to the barrel in a dovetail slot. simply tap it with a drift (or anything else that is handy and made of brass or other soft metal), and that will do it. You can put a piece of tape on the barrel and reference it to the sight in some way, so that you will be able to confirm that the sight is actually moving. It won't take all that much.

Anyway, move the rear sight in the direction you want the bullet to go (to the right in your case). If you do adjust the front sight, move in the opposite direction you want the bullet to go.

I have a Marlin 1895 and I removed the rear sight and put a Williams peep on it, which is awesome in the woods.

I have the 336 Marlin...the sight in the front is stationary..all adjustments are made from the rear sight. I bought the fiber optic sites for mine...they are great for low lighting but the site itself is cheaply made.....

If your gun is shooting 8 inches to the left..you will need to move your rear sight about 1/8 of an inch to the right.

i didn't think the rear site moved. its attached to the barrel with a step ramp. The front site can be moved with a site puller. At least that's what the guy at my pro shop did.

Hold on a minute while i get my 30-30 ....let me look again...stay right here. Lol


OK..i looked. I took off the site that came with it so i really forget how the old site worked. The site i have on there now has 2 set screws to adjust height and windage..However..i do know for certain that the front site is supposed to be stationary...however, if you must move it...it will move by getting a small punch and tapping it..i know because i had to remove it to put on my new sites. When i got the new site i had to file on the new front site to get it to slide in the slot...that was a pain..took about 20 minutes

Ps..you can tap your front site if you need to...it's a very tight fit and should not slide after you make your adjustment...my 30-30 shoots fantastic...kills deer on spot BUT not hogs..they need my 270

The step ramp can be moved forward and back. It's puropose is to change the elevation of your POI. The rear sight is mounted to the barrel in a dovetail slot.

The Marlin's have had several different sight set ups available. Most typical is a dovetail mounted rear sight with a step ramp for elevation, with a screwed on base with a dovetail mounted front blade.

If you have this set up, I personally would drift the front sight and keep the step ramp centered on the barrel in the rear sight.

Brute force method: place the barrel in a padded vise, use a brass punch and a mallet to drift the sight in the dovetail (opposite of where you want the bullet strike to move).

Poor man's sight puller: Padded bar clamp with a drilled and tapped hole near the top edge, small bolt mounted in hole. Mount the barrel in the padded clamp with the bolt positioned to push against the sight. Place a piece of cardboard or leather between the sight and the bolt, turn the bolt to press the sight.

Works with a pair of flat grip vise grips also.

8 inches left at 25 ??

Your barrel is bent or your rear sight is way way off center. Center it in the dovetail groove and start over.

Here's how to "adjust the sights" on your ol Marlin!

8" is a lot at 25 yards with fixed sights..............


Start with your rear sight !


BTW - I own a 336C in .35 rem

guys, my rear sight is not adjustable as it seems. Its fixed with a step ramp. My front site is dove tailed and can be moved left to right. I think this is the only way to site this gun.

I bet that rear sight is adjustable for windage. Never seen sights on a lever gun that weren't adjustable on the rear.
I could be wrong but I doubt it. Drop by a gunsmith and get his verdict.

Which site moves is irrelevant. Just drift it with a brass punch or wooden dowel, or build one of the screw presses I mentioned earlier and be done with it.

8" at 25yrds might be a lot bigger issue than just adjusting your sites. 8" at 25yrds vs a 20" sight radius = ~1/6" of drift needed on the sight (if you have a micrometer caliper, use that to determine how far you drift it, especially if you use a punch and hammer).

Why not just scrap the factory rear sight and install a Williams adjustable peep?
It's a much better sight and completely adjustable without special tools.
Not expensive either.

just talked with Marlin and they say the only site that can be adjusted on the 336 is the front site. It looks like they have put all different kinds of sites on this gun over the years. apparently my front sight is the only sight that can move.

Well I guess you learn something new every day. My last hands on experience with a Marlin lever gun was back in the 1980s.
Things have changed.

Good luck working out this problem.

Incorrect, according to all 336's I have seen. Check out the diagrams at the link below. If your gun has parts 40 and 41, and the barrel has a dovetail slot for the rear sight, the rear is adjustable. Sliding part 41 forward and back will change the POI elevation. Sliding part 40 left to right will change the left to right POI.

If your gun does not have these parts, and the dovetail slot, the sight should still be adjustable for elevation.

thak you for the schematic.. mine looks like this but there is no dove tail on the rear sight. It has what looks like 2 tapped holes on the top of part 40. They are not screws but look like pegs that are flush with the top of part 40.

Seems like a cost-cutting measure.

As I noted in an earlier post, I really like a peep on my Marlin. I'd remove the rear sight and go that route. You still may need to drift the front sight a little.
