Pdi Airsoft Parts

Tell me if this is a good j bar 10 airsoft sniper upgrade plan feel free to reccomend other parts and tell?
If I need anything else. Laylax 150 spring, pdi first sear, pdi second sear, laylax spring guide stopper, laylax high pressure piston (red), laylax spring guide, can you reccomend a good fairly cheap tightbore, hard or soft hopup bucking, and best bb weight and brand for this setup. Thanks!
Good and cheap don’t work so well together. But if you’re looking for some nice barrels, look for Prometheus, DBC’s, Edgi, PDI and TK Twist barrels.
As for buckings, I believe that it comes stock with a V-hop, so I’d get a Firefly V-hop bucking (hard type).

You’ll have to use several to find the weight you like, but I would start with .3g
Looks good to me, but I’m not a sniper or a sniper rifle specialist.
-edit
I forgot to mention, only get the TK Twist if you are planning to use it for a low F/S sniper rifle, which it appears you aren’t.
