I was wondering if the experts out there can educate me as to the differences between Browning 50 cal. M2 and M3 internals ?

Any information would help.

Thanks;

The M2 has a heavier bolt. The M3 has holes in the bolt to make it lighter. The parts like cocking lever pin are pinned in place so as not to shift position when firing at 1200 rounds per minute while upside down. The oil buffer actually has oil or hydralic fluid in it unlike the M2 which doesn't have anything in it. this makes the parts spring forward under pressure. The Feedway parts such as cartridge stop or link stripper or whichever exact version you have have a pinned rod holding them in because of the aircraft use. The barrel is thin and has a cooling jacket instead of barrel support and heavy barrel of the ground gun. The buffer group is huge compared to the spade and buffers of the ground gun because of the punishing it takes with the high speed. The receiver may actually be an M2 marked as such but won't have the trigger bar stop adjust nut like the ground gun. The M3 is fired with the side plate trigger or solinoid. No provision for hand firing. There will be no sights provided unless it's an M2 and then the holes will be there for the sight screws.

Remember these guns were in belly packs of the CF 100 or the sides of the Sabre and were meant to run high speed and cold air cooled at altitude. Electric firing. 65 pounds per gun.
 
The M-3 is one of,if not, the most impressive weapons i have ever heard firing, and that from a MG42 lover!:D

Great info from on the M-3 from BrowningAutoRifle.:agree:

Watch the color gun camera footage from US sabres over Korea to see the devastating burst from 6 of those .50s @ 1200 RPM each!! White trails at the high altitude from the tracers, impressive. Except for the M-3 .50s round being sometimes lacking at extreme engagement range and high deflection shots on the all metal MIGs, it would destroy any WW2 fighter from only 5 years previous, with a touch on the trigger.:)

Canadair Sabre. Wow!!

Sidester, I found some on Military channel Top Ten fighters. #4 spot shared by MiG-15 and F-86. The footage is what I believe I saw years ago on a documentary on MiG alley over Korea. I believe you can see the Sabre firing several extremely long range, high lead/deflection bursts at what I think is a MiG -15. Start watching at 3:50 and you will see the gun camera footage at around 5:05. The pilot fires 5 quick bursts on 3 and four you will see lots of hits and fire . Flight time looks about 1 to 1.3 seconds to target. You can see the 6 contrails left by the .50 M-3s nearly to the target aircraft. Its the best Color camera footage I think i've seen. Anyone more experienced than me might know this footage from some other type engagement/training shots, buts it looks like a MiG 15 over Korea. I believe this footage has been used somewhere else to show James Jabara's 5th kill making him americas first Jet Ace, though it may be just used to demonstrate and not be actually his gun camera.

You be the judge.:cheers:
