Okay so I need help...after 18 months I finally went and just got my gun from the local gunsmith who was suppose to correct the problem I am about to describe. About 4 years ago I had a Rugerr 77 re-barrled to 9,3x62 and an NECG (I think) front and rear express sight installed (island with single blade adjusted by a set screw) on the bbl by Jack Belk...took me forever to get the gun back from Jack and the rear sight was not even installed. So local smith installs rear sight (same one I just went and picked up the gun from).

Well as you might guess one of the challenges you face is dealing with "5 planes". You have the two integral scope bases on the Ruger plus the plane of the rear sight island base plus the plane of the top of the lower portion of the rear sight blade base plus the "invisible" plane across the top of the two outer corners of the rear sight blade.

When sighting down the bbl it looks all "caddywampus". So I throw the gun in the caddy and here is what I got.

Using the front integral scope base as an index (meaning) when it is level...the rear integral base is high on the right...and all of the other planes on the bbl mounted rear sight (meaning the base, the base of the sight blade, and the top of the sight are high on the left.

Should a smith be able to put the action in a fixture level with front integral base level and the mill the dovetail portion of the island reaer sight level so when the blade sits in it it will look level as you sight down the bbl?

What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

You might not want to hear this but my solution would be to remove the rear sight. Screw in a screw tightly in that hole that was drilled to the left of TDC & file it flush. Put the barreled action in a proper jig & redrill the screw hole to the rear of the first hole about 1/4" but this time be certain that it is TCD before the hole is drilled.

your right...I didn't want to hear that...not that it matters cause u r really saying make it TDC but if the left side of the base is high doesn't it mena that it is off to the right of TDC.

Hi Mike....your base is not profiled to the barrel contour....common problem with most manufactured components. Holes are probably OK. Remove the base and apply some blacking compound to the barrel and set down over the hole. You will see where it is contacting. Take a small round file and carefully reprofile the underside of the base untill there's full contact. Surprised you smith did not fit the base as it's a simple process if you have access to a mill. Good luck with your project, Ron

Mike if I'm reading you correctly, you're saying the factory Ruger front and rear integral ringmount bridges are not square w/ each other regardless the front and rear sights. Is that correct??

The armorer for my employer is a guild smith who recently installed various sights on three of my Rugers. He used an electronic centering device that was acurate to 1/2 of 1/1000, IIRC. All of my Rugers were square front bridge to rear bridge so I didn't have your problem. He squared the sights from that.

If your two bridges are out of square w/ each other enough to notice by the naked eye, I'd think it would be a warranty issue w/ Ruger. Left alone, your ringmounts would be out of whack probably more than can be corrected by lapping. If you remachined the two bridges square, I would think you'd need to remachine your ringmounts to fit.

If you have no desire for a scope, I'd line everything off the rear bridge in the event you ever install a receiver sight.

Hope I didn't cunfuse things,
GVA

GVA,

You are correct...when putting a level acroos the front mount it is "level" if it goes across the rear mount out of level..its not by much but we are talking about the the bubble instead of being centered that the edge of the bubble is even with edge of the center lines.

Mike you're right that would make that action worth a lot less to someone if you were to sell it. The truth of the matter is the gun smith that put that sight on the the barrel owes you a new barrel. His fault, his craftsmanship and he knows it. Hence the draging of feet he's trying to think of a way out and knows what the real answer is. Hope this is the last time you use the gentleman and I use that term loosely. Spread the work about his work if he isn't ready to stand behind his work.

Okay...i know I am being stubbirn but I really don't see why the base has to be re-installed cause it actually doesn't look off TDC it's the vertical sides of the blade that look and are canted to the right

Your description is a little confusing. Is the rear sight base integral or is it a NEGC unit? Is one side of the base actually thicker like the drawing, or does it just give this illusion because it's not level?

If it's integral you have a barrel timing problem and the barrel needs to come off and another thread added to bring the base TDC. That's assuming the base is of equal height on both sides.

If it's not integral I would have the rear sight base hole re-drilled and index everything (front and rear iron sight bases) off the front scope base. That's assuming the base holds the same dimensions when removed from the barrel. If not throw the base in the garbage and get a new one. You should be able to re-drill the holes and still have the old holes covered by the base. After awhile you'll forget your barrel has extra holes in it and you'll go hunting. Big Grin

Hey Mike, Don't really care if you don't like hearing the correct answer from me, but here it is.

You need to have the first Dovetail plugged. Just have a blank stuck in it. Yes, it will look belkerized, but shoddy metal work results in such stuff.

Then another Dovetail needs to be properly milled either ahead of or behind the belkerized Dovetail.

Just that simple " if " the problem is in the Dovetail - which it probably is.
---

You could grind off the Base on the Rear Sight at an angle, but it results in that side of the Sight Base getting narrower - it won't HOLD!

Turn the Rear Sight so you are looking at the side of it. Focus on the Bottom and notice the Trapezoid Profile. Draw a LARGE version of it on a piece of paper if it will help. Go up from the Base a bit and draw another line parallel with the Bottom.

Now measure the new line and the bottom and the new line is shorter - it won't HOLD!
---

Same applies to trying to un-belkerize the first screwed-up Dovetail. It most certainly could be cut down at an angle(with lots of effort and liquor), but it won't HOLD the rear sight.
---

You might have the belkerized Dovetail milled at the correct angle and then weld the rear sight in place. Or Super Glue it. rotflmo
