There are A LOT of companies with similar lines of business on FB. Was there something specific they found objectionable?

Glad to hear it went smoothly LOL, yeah, everything else is simple and requires trivial force relative to the extractor plunger - that one is a PITA given the size of the parts

make sure all the holes are properly lined up and give it a little tap - should go right in...

Anybody got an M60e4 trigger group they want to sell (should be marked US Ordnance on the grip)? Let me know via inmail or mhbits@gmail.com Thanks for looking... -- Matt

Agree - that looks like a nice package for the price... Congrats to the buyer. Hopefully they will show up here.

I was going to ask if the barrel was a newer one with adjustable gas (maybe you got it cranked-up to max (i.e. way overgassed if clean)?)

Hmmm - Sounds like chamber isn't rough... Best guess - some combination of the following: Excessive Headspace Overgassed extraction (is the barrel old/shot-out - eroded gas port?) Weak brass / bad ammo

One thing to check: Remove barrel in question from gun Does cartridge drop freely into chamber and fully seat? - it should If you turn barrel up, does the cartridge freely drop out? - it should

BTW, I seem to recall in one of Aaron's? M60 videos he mentioned something about corrosion in barrel chamber after just sitting for a short while causing problems... The video showed using an electric drill with a nylon brush to super-clean the chamber...

It certainly has a symptom of excessive headspace, but I wouldn't say it is 100% definitive. It is a really good idea to check headspace between all possible combinations of barrel and bolt you plan to use. Just because a barrel and bolt each are in-spec does't mean the combination of the two are OK to use. Swapping bolts/barrels around w/out checking HS usually works OK, but it can end in disaster...

What did the broken cases look like when you got them out? Were the case necks split? Did you look over all the other spent brass which didn't get stuck? Did you notice anything abnormal like split necks? How did the primer strikes look on the spent brass? Light/Normal/Deep?

Qs: 1) Same combination of barrel and bolt as before or perhaps you recently swapped barrels? 2) Have you checked headspace with a no-go or field headspace gauge? 3) Extractor look OK?

IMHO, if possible, that sounds like good advice...

FWIW, Just had an an e-file F3 approved in 2 days

Mail by FedEx - yes By plane - Yes On line 8, I always put the following: "Automobiles, busses, trains, boats, aircraft, private and commercial carriers"

Most people collect these in pristine/unused condition. Of the 3, the M2 is by far the most rare. There are videos on youtube of them in operation. I think Tippman makes paintball guns now. https://www.tippmann.com/

> As I understand E3, E4 and E6 internals interchangeable, not counting for dimensionally similar improvements. This is NOT accurate. An e4/e6 feed cam will NOT work in an e3 top cover. The angle of the e4/e6 feed cam results in the feed lever moving to a greater angle which will hit the inside of the e3 cover. The e4 & e6 covers have a small relief that allowsthe feed lever to fully rotate. It is possible to dremel a relief in a SACO e3 cover so that an e4 lever will properly function in an e3 cover. Look at 11:38 in this video that shows the difference between an e3 and e4 cover and note the small relief in the e4

I do like johnsonlmg41's idea of using a modified M60 gooseneck pintle on a MG42 AA tripod. That + a London bridge 100rd ammo pouch and you are GTG (https://lbtinc.com/products/0261) Very very light relative to everything else being discussed... I've got extra of all that stuff just laying around, so, I might just give building that setup a whirl... Wish I had a milling machine to turn down a gooseneck pintle or make an adapter... I guess I could turn it by hand slowly on a grinder.... Any other suggestions?

Sorry, first link was the 6ft tripod (instead of using M122 + riser) https://www.gunbroker.com/item/819806441 I have one of these - very nice

I like...I like....but doesn't look tall enough on an M122 tripod to stand & fire..... LOL, How tall are you?!?...... FWIW, the second option above is for a heavy-duty tripod that extends up to 6ft tall... I'm def intrigued to see what you end up choosing...

If you want to stand, buy one of these + the M142 https://www.gunbroker.com/item/819806441 or M142 and this https://www.gunbroker.com/item/813461991

There is an M142 with the long pintle on ebay now: https://www.ebay.com/itm/333263239691?ul_noapp=true

These guys will have multiple options & are very helpful... https://www.bmgparts.com

Here is an H-60 that would work on your tripod directly... Just need a bolt-on ammo can http://www.sturmgewehr.com/forums/index.php?/topic/13884-wts-navy-h60-m60-cradle-mount/
