I bought a Colt barrel assembly from Clyde armory (one of the ones used in an armorers course) and while inspecting it I noticed the FSB pins weren’t drove in the whole way. This has got me thinking that the FSB was likely removed multiple times during the courses and I wanted to know if it would be a good idea to get some new pins. I’m planning on replacing the barrel nut as it is (the teeth are really chewed up), so I wanted to ask if replacing the pins would be a good idea.
The Colt pins will sometimes not be flush with the FSB due to the taper. If the larger side is not flush it is less of an issue than the smaller side. If you can see raw metal exposed on the FSB on the small side your pins are either the wrong ones or too short.
The pins are barely in. I was able to tap one out with very little force.
I would say the FSB pin channels are reamed out. Even new pins may not fit tight.
You can go with a FSB that uses screws or have a new one drilled by a gunsmith.
I should have clarified. The pins weren’t driven all the way in and I wasn’t going to try until I replace the barrel nut so I have no idea how tight these pins fit. I was just curious if it might be a good idea to install new pins since I have to pull the FSB anyway.
Use what you got. If they fit tight, good. If not, you may have other problems. I think someone just left the pins loose for whatever reason
They should fit fucking tight, Jack! It is a bitch to knock factory Colt pins out.
If they’re not damaged on the ends, they’re fine. Replace the nut with a REAL COLT part. Then hit the pins back in with a good punch that has the concave tip.
The ends of the pins look fine. At any rate the barrel will be going to Adco at some point so I guess they’ll be able to see if anythings wrong. Thanks for the advice everyone.
They should be fine.
I would have never bought one of these barrels for the price they were selling them for.
You could have bought a new barrel for just a bit more.
IMHO, these barrels are worth $100 or less.
The pins are most likely not fully hammered in because they want to make it easier for the end user to initially remove the pins in case the user wants to install free-float rails.
Did you read the thread?
These are barrels from Colt armorer’s courses that have had the pins removed and replaced several times.
They are junk barrels with jacked up front sight bases and barrel nuts.
Yes, I read the thread. I don’t dispute that they’re probably junk barrels…
The question is, did you read the thread? He hasn’t even tried to install the barrel, yet, or punch the pins in, so my posts stands.
I have to agree. In my experience any used part that has come from any armorer’s course (unless it is originally your part) regardless of who is giving the course has been subjected to R&R more times than any manufacturer recommends.
The proper course of action here is to sell off the junk barrel and move on.
Not pour in more money on the junk barrel.
have to agree with this sell it and go find a new barrel or at least one that was not tore down over and over
scottryan and warpigM-4 have a good point. You need to figure out what the total cost will be by the time you are done “seeing” if it is any good. It is a judgement call. If you think the pins can be installed tight than keep it. If you have a doubt than sell it and go new. My concern is if the pins are still able to be installed tight than why remove it from the armorer course in the first place if it can still be used to teach.
Exactly
These barrels were sold off for a reason.
Pinned on FSBs were never intended to be removed.
What I find interesting is that I have never removed an FSB in a Colt Armorer Course. Is this something new?
I was also wondering about this myself as there is no reason why Colt would be teaching this, as low pro gas blocks are not Colt doctrine.
