I need M-14 or M1A rear sights to relpace the low quality rear sights that came stock with this paticular rifle. It is an M-305 by Norinco.

Thanks

You can use M1 Garand rear sight assemblies.It is a simple swap. They are the same except as the M14 rear sights except the Garand sights are marked in yards.

SKBY.
 
Brownells will, because it's an M1A sight, not an M14 sight. No export controls.

What's up with Trade ex? Links don't seem to work, did their site go down?

I'm interested in getting some Garand sights for my M305 but I'd really like an elevation knob in meters, I'm a metric guy, what can I say. Anyone have a source for M14 elevation knobs?

Don't bother going to metric. Save your money for practice ammo. The difference between yards and meters is insignificant for the OSA philosophy of Minute of Bad Guy (Figure 12C that is). There is a minor mathematical difference, but not enough to make any obvious effect. OKelly'sBoys found the front sight was the width of the 4x4 paper after 300yds, and he could see all three targets in the aperature further and further back.

I'm no great expert but my recommendation is if you want to shoot irons for distance on a regular basis switch to a good set of Garand sights and throw a thinner National Match front post on if you're going to compete.

I've only shot the Nork factory sights at distance just the once. I don't remember the 400 but at the 500 and 600 the front sight post is definately the width of the 4x4 board. The target is a black pin prick on a white dot dancing on the top of the front sight post. At the 600 I could see both targets on my right in addition to mine through the aperature. If there had been shooters on my left I would have seen them too. So at 600 you'll see 4 or 5 in total through the aperature.

By the way, 600yrds=548.6m So at the greatest distance you'll shoot in competition the difference is 51m. Someone else will have to chime it about the impact on sight adjustment.

Cheers,

Just a note here about the SA sights from Brownells: they may not be compatible with your Norc. I bought all the components to make up a rear sight assembly, and the windage will not adjust on my gun (this may have even aged Hungry a year or two at the clinic!). When the windage and elevation screws are aligned to properly mate together the remainder of the sight collides with the sight sides on the receiver. When the sight is offset slightly to overcome this, the elevation and windage screws don't fully mate together.
YMMV.
 
I have found with my Garands that I have had rebarreled to 7.62mm I just read the dials in Meters instead of yards, seems to work quite well!

That's interesting. I've got the SA M1A windage and elevation pinions from Brownells in both of my Norc's. They were a little finicky to put together, but once in together everything appears to work fine. Windage and elevation both work.
 
My brother and I have been pulling our hair out trying to zero his stock Norinco rear sights. He followed the standard USGI procedure, people at the range tried to help him, but nothing. At 50 yards it is okay, but at 100, it is always off the page no matter what we adjust.

I bought a nice M-1 Garand rear sight. If we bottom it out, I think it should work fine once properly adjusted.

The question is, how do you install the new sight assembly? How do you knock off the Norinco sight assembly and place the new Garand one? I'm going to check a field manual later in the week.

From Hungry's clinic, there are some salvageable Chinese parts, but the knobs and pinions aren't normally in that category.

The bases and springs are likely to be OK, but it will be hit or miss on the aperature. The knobs and pinons don't stay where they are put. The majority of Chinese ones are that way so don't feel bad. Throw them out. The bases and springs are probably going to be OK, just test after assembly for solidity and clearances. The aperatures will have a few quirks. We saw some with a sharp angle where the forward face of the eyepiece joins the curved shank. Not desireable because there is a weak spot right there. Some had a more sloped angle there. More desireable with more metal to resist blows. But one recent delivery had a nice tiny hole - drilled way off-centre. Useless for logical locating, but probably a decent shooter because of the National Match diameter hole.

So, USGI Garand parts slot right in. USGI M14 parts are even better. Springfield-brand M1A parts have a bad reputation. Brownell's aftermarket stuff is good, but XS brand sights need a shallow recess drilled in the sight ear for a tiny ball bearing to engage the clicks. Be warned.
