I'm a machinist so I just turned a piece of aluminum round stock bored it 3/4 " put two 10/32 set screws in it slid it down the barrel and blocked the gas port. There is no gas tube and the forearm almost covers the collar. I run a standard buffer and spring. At the range I use a BobSled so I can load longer than mag length. Been trying lots of different bullet weights and charges. XBR seems to be the powder so far.
