What type of heat transfer are you guys getting with the long stroke piston system of the PWS guns? HK flaunts the merits of a short stroke non heat transfer to the bolt.
TIA, SK |

TIA, SK There is more heat transfer with the PWS system than you'll see on some other designs. Does it really matter? Probably not. |
| I'm thinking the whole short vs long is BS. The gas hits a face of a piston and pushes back, it would seem to matter not a bit how long anything is, as every system is as long as it take to hit the carrier. Theres no long stroke dwell time. As in every system, the gas is dumped right at the piston face, so the heat is there and no more or less than any other at the BCG. |
