if you can't find someone with FSE HTS for sale you can pay a bit more & get em from DSA.
...another big plug for Moses (
[email protected]). i've bought stuf from him at good prices. in fact he has some of my parts right now doing a trigger job on an HTS bound for my SA58!
(hoping i get em tomorrow so i can wring em out at The Pit monday![c'mon, Johnny!!
] )
get his LS rod while you're at it if you're building yourself.
OR
go with US made PG, CH & piston. (in addition to the para-keet & receiver that'd be 7)
those 3 cost a bit more cumulatively than an HTS set but not much and if the CH and/or PG from your kit is chewed then it's viable. any austrian piston will probably be in fine shape.
the STG FH is kinda long. are you leaving the barrel of cropping it?
if you're cutting it down you might look at a Belgian combo device or ???? lotsa aftermarket stuff out there.
IMO the shortened STG units i've seen look the business but i don't know if they still FH.
somethin to chew on....
