The PWS MK109 in 300 BLK will only cycle subs if there's a supressor, which will be ideal when I have an extra $1100. Until then...

I would like to setup the rifle to properly cycle, but don't yet have the money to spend on a can. Does anyone know any other device that will increase the backpressure onto the bolt and gas system, as much or near as much as a can, but doesn't require a stamp?



IDK if there are any other calibers that have a similar cycling issue when using different handloads; but, if so, the issue is the same and your input will be appreciated.
