WTB Upgrades for Empire Sniper (Inception Designs)

[HalfThank]

Looking to upgrade a stock Empire Sniper. I figured I'd check in with folks before starting to buy new parts. In approximate order of priority:

1. [x] ID o-ring rebuild kit (w/ new reg seat).
2. [x] ID Universal Hammer
3. [x] Main and valve spring kits (anticipating tinkering with spring tensions after I drop in an ID hammer and maybe Laz valve)
4. [x] ID drift kit mid (w/ fluted rod)
5. [x] ID hitman plate for drift kit (I can feel your judgement)
6. Lazarus Valve (never hurt to ask?)
7. ID mamba trigger & roller sear

[x] denotes I already got that part

I expect this to be a multi-month project for me, so I'll update this thread as I acquire different items. So if you're seeing this post some time in the future and the list isn't entirely crossed off, I'm still looking for some parts!

Thanks.
