Good question OP and I am sure it has been well answered. To tag along to your initial question I will throw this out there. Why in the name of god did Canada hang on to M1919/C1/C5 MG for so F,ing long when the MAG58 (later C6) came into being? The C5 was a fun gun to tinker about with to get working half way reliable on a range but to go to war anytime after the 1960s would have been a sick joke. And next is why did we (Canada ) not replace the old war horse Browning HP during the SARP ? No doubt that old gun will be still around for a couple decades to go at the way we love to drag procurement out.
Awesome topic.Both were a bit of a mistake. The "squad automatic" is far better off being a belt fed, as opposed to a magazine fed weapon.
As to why a new gun instead of recycling an old one, perhaps it was a combination of modernizing as well as commonality of the parts shared with the C1. But in the role of suppressive fire, a quick change barrel (as on the Bren) would have been a better option than the fixed barrel of the C2. Perhaps weight was a factor. The C2 is lighter and easier to carry than a Bren.
The Australian Army adopted their own version, the L2 and along with the M60 took them to Viet Nam. This worked out so well that 7.62 cal Brens were imported from Britain
How many of you c2 experts, have ever carried a C2 or shot Live rds out of one, You say how accurate a Bren gun is, How with a C2, first shot on Target, and rest all over. ON ANY SHOULDER CONTROLLED FULL AUTO Rifle, You SHOULD have a beaten zone about 6 feet wide and 12 feet long, A beaten zone is WANTED because more people are hit. Auto fire is not putting all you shot in the same hole,or killing one man 10 times, Even the so call accurate Bren gun when fired on full auto, will jump around, as will the American Bar. I have fired 15, 30rd mags, 450rds on full auto. Weapon take in and had barrel checked on return from range. NO DAMAGES. , Had a Trooper as a loader, Shot till all mags empty, no stoppages. That was NOTHING WRONG WITH THE WEAPON , In the time period of it,s use. Nothing.
Well there is some benefits to the C2 from a practical standpoint.
1. Its weight the C2 was 13lbs vs 21lbs for the Bren.
2. Common parts with the C1, which is something most people seriously underestimate the value of (you only need a small amount of extra C2 specific parts as opposed to a whole section of completely different parts that was required for the Bren, simplifies training for armourers, and keeps things easy logistically).
3. The Bren L4 required significantly more maintenance to keep running than the original .303 Bren. The original .303 you could basically ignore and periodically do some small maintenance to, the L4 was constantly requiring maintenance as 7.62 Nato was pushing the design (paraphrased words of a British Master Armourer from that era).
It really surprises me the hatred some have for the C2 considering it is basically just a C1 with a full auto switch and heavier barrel (especially considering how so many love the C1). I know my father loved his, but that's also just him as well.
