Hi Bill ,Ya I'm into gun's to say the least I have built some good shooter's mainly in .223 .308 & 50 bmg...One of the REM .223 PSS's shot so good the Anchorage PD wanted it for there CIRT team I shortened it from 26" to 20" and threaded it for a can ,It's very quiet with 3000' per second ammo and with sub sonic ammo it sound's like a pellet gun ...I also do alot of work on class 3 gun's (such as machine gun's supressor's and SBR/SBS ecc.) it has been a hobby of mine sense 1983.... Lately it has taken a back seat to plane's LOL...so many thing's to do,so little time....JW
