Lower egging prevention

If egging isn’t an issue, why does Sam weld in reinforcement tabs? Because egging is an issue…. I don’t disagree that the upper alignment with the lower is where it comes from, but a consumable pin is way easier than filing out a form, shipping it to Sam (which probably costs as much as a pin), worrying about the ever so competent courier losing or destroying your lower, paying Sam to do the service and re-park, the worry of the courier on the trip home.

Sam does excellent work, and has done work on my baby mac. Just saying, a pen that costs $20 bucks or so, is a cheap investment.

Good point.

100% agree with this.

I shipped one MG for repair and worried the entire time it was in transit.

Pin is probably $0.50 in material and depending on complexity, half an hour of time or less. Much less if making them by the handful on CNC. $20 for a pin sounds insane to me.

That is because you have the machinery and skills to make that pin. The vast majority of members don’t. It is my understanding that the only Mac style RRs that don’t have the front tabs are original Powder Springs guns. If the front pin holes become oblong, then pug weld and redrill the holes.

Anyone with the tooling and skill it's extremely cheap to make. Those with CNC lathes can kick them out by the dozens per hour. at $20 each it's basically printing money.

I feel bad about what many places are asking for simple machined parts so I tend to way under bid or let customers pay what they want. Had a local guy pay $250 for a barrel nut for an AR10. Took me probably 70 minutes to make in 416SS having never run that material on my lathe before and never doing internal threads before. I was thinking more like $80 for material and labor. He wouldn't go lower. Another guy offered $200 for a 3D printed sled for his AI rifle. Yeah, took me 3-4 revisions to get it perfect but it was only maybe an hour of CAD and then I just sit and watch the printer. Maybe $5 in material.

Yes, I know my shop rates are generally really low. It's not my day job. My shop is generally personal use only unless someone needs a favor.




My 1973 PS gun does not have tabs. If tabs were welded in I would not be able to use my factory upper without modifications.

If you want to make some, I’ll buy them. I just said $20 as an arbitrary number. I know the steel ones are at least that much.

Plug welding and re-boring along with re-Parkerizing (like Sam would do), is a good option, but I’d prefer to leave mine alone for the time being and buy a somewhere less than $20 pin😂

A couple years ago I bought a prevention accessory for MAC retention pin hole egging - a Fleming .22LR upper. Lowered the cost of ammo used in shooting as well.

Also, there really isn’t a good way to effectively insure many MGs when shipping except to take out a separate policy, which is much more expensive than a pin. If I ever have to send one of my MACs to Sam, I’ll probably just drive and make a vacation out of it. Lots of pretty areas around East TN.

 

[Deerhurst]

Completely agree, I'd rather drive from Oregon than ship my MG.

My M10 .45 came with tabs bought this new in 1983 NIB Powder Springs.Never had a problem with that.Good luck.

Original Powder Springs M10s and M11s shouldn’t have tabs in them, unless they were added by rpb or swd (left over stock).

I already decided if my M10 has to Sam’s or anywhere else I’m driving.

Yup. No way in hell I'm trusting anyone that hires anyone like the quality individuals that sort and deliver packages in my town. They can't be trusted with an amazon package. It's not insuring it or anything that's the problem. It's replacing it that is the problem. And dealing with the shipper. Only so many transferrable MGs out there and I am the custodian of one.

Yep,just dug it out of the safe is marked Powder Springs and RPB.

But your gun is a double stamp. It was made by RPB from a Powder Springs flat. By that time the design had been taken over by RPB, they knew that the front lug of the upper had been narrowed and the front tabs added to the lower. The original design didn’t include the reinforcement tabs.

I also would love to have the tabs added, but I'm too worried about shipping the gun, or having end up at the shop for years...

So call Tina and ask. It would seem to me that Tina would have communication with Sam about the schedule. It is my understanding that usually Sam will tool up for specific tasks like doing tabs just before doing a bunch of refinishing. So you could time your shipment to arrive a week before or whenever Tina recommends to ship to get inline for the next batch.

Recently I have dealt with shipping machine guns. There have been some changes since Covid. DHL will not ship any firearms. UPS will ship Title I but not Title II firearms. FedEx will ship machine guns, but only between SOT FFL holders, and only overnight. The only way, you as a private individual can ship a machine gun, and not lie to the shipper voiding any insurance claim, is through USPS. They don’t differentiate between machine guns, SBR, SBS, handguns, or pistols with a brace. The two designations are concealable and long guns. So to ship your machine gun it must have a 16” barreled upper on it.

To me, the best shipping option is by Registered Mail with insurance. It is the least expensive option of all and should definitely be the most secure way to ship it. I spring for Priority Mail on top of that. It’s only a few bucks more.Good luck with your tab reinforcement project.
