well ricochet well test it with my gun. for those curious I have a 2012 ptw evo with a m4 inner barrel and a cqb outter barrel. the inner barrel is covered with a magpul pts aac 9" dark earth silencer with foam inserts and a spring insert.
we will test with my excort 3200 Chrono *sorry for spelling errors* in a 100 foot enclosed building. shooting what we feel is the best B2B, bastards. at time of testing well take a reading of environmental temperatures and pressure so we can have good reliable results
if there is anything else ud like us to check to help verify results please let us know.
