Ran across a 90t high rib at a shop and it felt nice.Never had handled one before but have seen posts about guns having "had all updates done".
What are the updates and how do you know whether or not they have been done ? Anything to look out for on them?
1 locking block angle changed at some point during production history to be more robust. Some later guns came with the new angle from the factory. I believe all HPAR (high post adjustable rib) guns came with this upgrade already integrated from the factory.
2 forearm iron lug was made bigger at some point. See picture for what an updated gun looks like:
Several people I know shoot these guns a lot without the forearm update. I would not be scared of a gun that wasn't done. Mine is not done and I have every intention of shooting it till it breaks before I send it in.
My daughter-in-law was trying one out a couple years ago at a State shoot and I came up late in the round and asked my son how she was doing. He said, 'if she buys that, I don't want to shoot against her any more".
I have owned both low rib and high rib models. For some reason the high rib HPAR just felt better balanced to me than the low rib model. Sold my HPAR, it is the only gun I've sold that I regret selling.
The updates are no big deal to get done if you need them. Contact GunDr on this site and he will help you out.
It's been a while, but I'll try to recall some numbers during production.
About 3800 guns were produced. I know definitely there were no serial numbers over 4000.
The production serial numbers started with ST00100. There are a few guns less than that, but they were all special orders, and not all of them had "real" numbers. Some of the "numbers" had the owners initials as part of the serial number, some had birthdates, some had wedding dates.
All of the guns produced were produced with the same quality, from start to finish. True, there were some changes.....
Maybe to serial number 1200-ish, the bores were larger, around .747"-.755". This was impart because Remington furnished the blanks already hammer forged to .745". With consecutive bbl shipments, they kept tightening them up at our (Kolar Arms) request. Eventually, we were able to provide a finished bore at .742"-.745", with about .033" choke.
The hi-rib adjustable 90-T had tighter bores from the start...738" with .040" choke.
A mechanical change took place around serial number 2600, give or take 150. This change was to replace the 10 degree angle of the locking bolt and the lugs on the bbl to 8 degrees. The 10 degree angle definitely gave the life of the bolt maybe 40k rounds, but at 20k or so, it would no longer hold itself to the bbl lugs, and it would want to pop out of the lugs during a shot.(the top lever would move). With the 8 degree angle it would not. This may have shortened the life a bit, but still, 30k-35k is still a lot of shooting. Most all break-open guns are that anyway.
The fore end update you may hear or read about from me was never done to any gun during production. I started doing them while I was still at Kolar, but it was 2 years after the end of production. The angled little "shoe" was/is the weak link in the gun. I was replacing some as many as 2-3 times a year on the same gun. The update did away with the sharp angles, and allows the new insert to freely position itself behind the lug on the bbl squarely.
As for the wood, the early guns had nice figure with "kind-of" an orange color. As more shipments arrived, the finish darkened up to a more uniform brown. This was to help us not to spend so much time matching butt stocks to fore ends. The wood was furnished by Reinhart Fajen.
There were 4 options for wood dimensions....
#4...1-1/2" straight comb
All of the hi rib guns had an adjustable stock.
Early production guns could be had as special orders, with many options...adj combs, adj pads, porting, choke tubes (Kolar tubes), extra triggers, release triggers, extra bbls (including a few 32" bbls).
I believe it was 1991 that 50 guns were produced for the ATA, one for each state. They had a little engraving on them, including the shape of the corresponding state on one side plate and the ATA logo on the other. I don't recall how they were serialized (maybe someone may have one and could fill this part in).
Not all of the "state" guns were sold, and they were sent back to Remington and parted out. During the big regime change at Remington, the employees were able to piece guns back together and purchase any firearm that was still available in the warehouse. So, some of those parted out "state" guns got put back into circulation, but with miss-matched parts.
I hope this helps fill in any holes to the 90-T lovers (I love my 90-T).
The earlier guns did have larger bores. Remington supplied the hammer forged blanks and because we were aiming to have bores of around .742", Remington's mandrel was at .742". By the time the rib was installed, the barrel straighten, we had to bore the barrels to a larger ID to get things to clean up.
When we ordered more barrels, we would request Remington to forge on a smaller mandrel. Each time it was only about .005" smaller. Eventually, by the time we got to around serial number 1500 or so, they finally had the mandrel down to about .730". This allowed us to get the std 90-T to about .742" and the hi-rib 90-T to .737"
It was Remington's request that the hi-rib 90-T have a bore of .737". Apparently there were some squeaky wheels on the ranges that said that .742 was too open for a trap gun. Remington also said to leave more choke (.040" )in the hi-rib guns for the same reason.
The state ATA 90T that I have is serial numbered with an HF for hall of fame, then a dash, then the number that the state came into the union, then a dash, then the two letter abbreviation letters for that state. Example HF-00-xx
Anyone have a manual...and or instructions they could email me at [email protected] on how to properly change them from eject to extract ? I actually bought a couple of all original hi ribs tonight. Factory bores..no tubes...all numbers matching.Thanks for all the info!
