Early M16 rifles being used in Viet Nam

[RCS]

Old photos showing some of the early variations of the M16 rifle being used in Viet Nam.

Never found a 30rd magazine photo ?

I did add the short barreled M60 photo

[Jakeroub]

Those cutoff M60s were used in helicopters, no?

[RCS]

here are some additional photos of a short barreled M60 mixed -in with some Stoner machine guns from Viet Nam

The photos that I have posted of short barreled M60 m/g's were used by ground forces, do not about any other applications of the short barreled M60 ?

All custom done and wouldn't afford you much in saving space. I never found the M60 too bad in the Australian jungle...

Wont get many more out of these barrels a destructive test carried out on the barrels. Place/Date unknown

John Stryker "Tilt" Meyer cut down an M60 to make it lighter and handier in the jungle. He also cut an M2 Carbine down to use as break contact weapon.

Here's a bit about that. Worth a read. What Does Destruction Testing on Firearms Tell Us?

[Peter Laidler]

During our very basic (basic, but 3 years basic......) traninig as UK armourers, barrel shortening was always a discussion point. Later on, when you became more proficient, a the RMCS, Shrivenham, we would cut barrels shorter for various tests. After an inch or so, the accuracy would drop off and shortly after that, functioning of the rifle became highly problematical due to what we called volumetric pressure or loading.

I wrote it all up a few years ago, relating to L1A1's and Brens. Shortened barrels.......... A bit like mickey mouse watches. They look good, but they ain't much good for tellin' the time! Just my experience of coutse

volumetric pressure

Then they have to go in with numbered/lettered drill bits to increase gas port size and pressure and so on...guess work at the field level.
