Any suggestions on what the best can for a HK53 clone would be? Using an HK brand threaded barrel.
How is accuracy for the 53 with the can installed? It is my understanding that there are two issues with barrels of less than 10" for use with a can. The first is the pressure and to a lesser extent the temperature of the gasses leaving the barrel. My understanding is the pressure decrees behind the bullet the further down the barrel the bullet goes, after the first couple of inches. So with a barrel less than nine inches the powder is still burning and is still at a very high pressure. So this very high pressure gas hits the first baffle with more force and temperature the shorter the barrel is. As with most materials, the metals tends to soften with an increase of temperature. So with many shots in rapid succession the materials of the can, especially the first baffle, the temperature goes up and wears more rapidly per shot at higher temperatures. That is why AAC tends to use Inconel (which handles high heat better than other metals even stainless steel) for the blast baffle (the first baffle the propellant gas hits) in their rifle caliber cans. But there is a limits as to temperature and pressure any material can stand. There is also a factor of the materials in the powder. If there are "fillers" in the powder to increase volume but don't burn up and have some mass, these fillers can act as the media (the sand) in a sand blasting machine. These particles can hit the baffle at a very high speed and wear the internals of the can. The shorter the barrel, the faster and harder these particles hit the internals of the can.Here is my 53 with an AAC M4-2000.
