Stud inside receiver

[mbonner]

I am blessed with 3 12 ga 11-87s and a 28 ga 1100.
I have 2 identical Sporting Clays 11-87s, one was involved in an accident, I ran over it with my quad, at least it was not my William Evans BLE.
I noticed that on the one not damaged there is a stud projecting inside the receiver which seem to locate the barrel as it is inserted into the gun. On my heavy 11-87 Special Purpose
this stud is much bigger and the corresponding slot in the barrel extension wider. On the damaged gun it looks like the stud is sheared off.
My question is, there is no mention of this stud in the parts schematic. Does it matter if the stud is not there as the barrel seems to locate on the mag tube anyway.

While the mag tube and the rear forend support do tend to hold the barrel fairly snug, that stud is the key component for locating the barrel correctly. The first sign you notice that the alignment may not be right may be a broken extractor or a buggered up extractor slot in the barrel. I would get it replaced. It is pressed in and not shown as a separate part on the schematic as you have discovered. I might enlist the help of Remington on that one. I am betting they have a special jig that makes quick work of it.

Thanks, Virginian, looks like a gunsmith job to me, I'll take it to my guy and see what can be done.

Virginian, I took the gun to a 'smith who is familiar with 1100s and 11-87s. He actually has the studs and the staking tool. They are not the same for all 1100, and 11-87s regarding diameters He says the barrel extension locating stud is a rivet installed into the receiver during manufacture from the outside, after which the receiver is polished and blued so you can't see it. He says that he will replace the shorn-off rivet by tapping it out but I will be able to see the head of this blued rivet on the outside of the receiver after he crimps it in place. Fine by me, as I did not want to shoot it as it was with no locating stud. As you say, nothing about this in any schematic I have found. It was all news to me,

I hate to be the bearer of bad news, but I don't think your gunsmith knows what he is doing. None of the receivers I have looked at have the barrel locating stud mounting hole drilled thru the receiver wall. If you look at an 870, or your 28 gauge 1100, the ejector rivets go thru the receiver sidewall, and they are finished and blued with the receiver, but you can still clearly see them from the outside. My 1100s have nothing showing and my 11-87 didn't either. If the latest 11-87s are different, I stand corrected, but if you can't see the stud from the outside it does not go thru the receiver wall.
I have not seen all of them, but on the ones I have seen the stud is the same size, but the part that enganes the barrel must be filed to fit and to hold the barrel straight. The nub that engages the barrel is not perfectly centered on the stud on many guns.
Call Remington if you don't believe me.

Virginian, I checked the Remington website FAQ, and I found the statement that if the stud was missing it did not matter, and I printed this off and it is in my hand, it said that the stud was there only to guide the barrel in, if it was missing it did not matter.
Anyway the stud is going into my receiver, my 'smith says he'll turn one up on his lathe.
As a matter of interest, the stud is smaller in diameter on the 11-87 Sporting Clays Model than on the regular 11-87s and 1100 barrels, presumably to ensure that only the proper 11-87 SC barrel is inserted into the gun.

I don't know how it is now, but they used to have one standard sized stud, with a larger base, and you had to file the stup portion to match your gun for an optimum fit. The stud was only like $3 from Remington. I wouldn't think you could find a machinist who would turn his lathe on for that, unless he's a friend and he's just doing it to help you out.
I don't care what Remington says, I have seen extractors and/or the extractor barrel slot get messed on guns where the stud was broken or missing. I think you are taking the wise course in getting it replaced.
