Fantom

You can get one to fit almost any barrel. And almost any size and thread direction. Make sure you know the diameter. PWS makes many sizes for different barrel as well as caliber.

I got mine from Blackjack. Have not installed it yet. Waiting on a die from Dinzag. I got some great info from Primary Weapons Systems web site. They answered fast to my questions.

I did the FCG, Buttstock, piston, P/G and added a safety lever BHO and button to move the lever with my trigger finger. Hunting pigs in thick growth means shooting on the move at times. The Holo is fast, I keep both eyes open and don't have to worry about perfect stock placement. I do like it, and on the range hit fair at 100 yards. I can clean the gun with the sight in place, and for fun shooting remove it fast.

Thanks to all that have posted here about converting. Danzig, Bullshark and others put up with a lot of questions that made it easy. The biggest suprise was when I found that the Tapco factory is in my back yard.

Why change the piston? What is the advantage? Noobie!
