I received a 180 series Mini-14 from my father many years ago. I took the scope and scope mount off for it never kept zero. I wanted to put the rear iron sight back on, but over the years the original parts have been lost. Several months ago I called Brownell’s for a rear iron sight and they recommended “a rear sight assemble”. I specifically asked it would fit a 180 series, and their answer was yes. After assembly though, my problem is that it shoots 6-7 inches high at 35 yards and I am at the downward limit of the rear sight adjustment.

I am not worried about 1” MOA with this Mini. I just want to be able to hit a pie plate at 100 yards with iron sights or a red dot scope. Anybody have any ideas on how to pick up an original 180 series rear iron sight assemble or a secure scope mount for a red dot?

Have you tried numrich arms website-they might have parts?

Don't bother me-I'm reloading!

Can you show us a picture of your new rear sight assembly and one of the front sight? There is a rare chance that you have a very early 180 (similar to the prototype models), which had a very different front sight (a bead like a 10/22, not the ramp they used up to the last prior to the 580s) and a slightly different rear.

6-7" high is pure-D wrong if you are bottomed out on the rear.

Finally, you can always ship it back to Ruger, or at least call the service department there and inquire about your issue.

Thanks for the replies gents. Attached are three photos. My Mini is the 180 Series and a 200th Year of American Liberty type so it does have the ramp front sight. The Brownell's replacement rear sight assembly fits, but doesn't seem real tight or secure. TIA

On your last pic you show the sight mounted. There is a small space in the front under the sight. My friend has the same 180 mini and his is very similar to yours. His too has that space and it is not very tight. I would guess what you have now will work. Ruger states on their web sight that they no longer support 180 series minis. So they will be no help. Good luck on getting your sights lined up..........................Joe

mine like that have a little play in them if you push the front down.
you're probably good to go and just dont realize it.

if that's the sight that was originally on it and still is shooting off by 6/7 inches, then there's something else in play that needs to be addressed.

That is the sight that is on my 180 Bicentennial it has a M-14 type flash hider sight. You may have to just get a taller front sight.

I like your flash hider/sight. Where did you get it?

You stated "downward movement of your sight" has me wondering. You physicaly lower the ring and look at the fixed front sight,would not lowering the ring raise your POI. Kinda like a see saw with your front post being the pivot. I could be wrong!!! Would not be the first time .........Joe

No you raise your rear sight to raise your point of impack. Look down your sights and just raise your head and look over your sights. In a sense you are elervating the the barrel. Same thing.

It came on my rifle but I think Choate make one? Here is what I came up with.

Thanks. Hope it fits a 180 series rifle. I'll have to call.

I went to Numrich Arms and ordered an original 180 series rear sight base. I am hoping that after combining parts from Numrich and Brownells the rear sight assembly will be closer to original.
