The South didn’t have the industrial capacity to match the Union’s arms manufacturing and they certainly wouldn’t have been able to purchase arms from Colt or Winchester.
They must have purchased something like half a million Enfield muzzle-loaders ..... and a rather elaborate "gun" called the C.S.S. Shenandoah ... hard to explain why numbers of English repeaters didn't find their way into Confederate service.
Chowderheaded retro-blimps running procurement programs in Horse Guards Parade? No repeaters for Her Majesty's troops => no repeaters for General Polk either?
