What choice of better bolts do i have for a pm7? i couldnt find what other years or dye guns fit the pm7 to even begin looking. thank you!

I thought the only upgrade to these bolts were the Billy Wing bolts, but also not sure how much of an upgrade they are.

[Myrkul]

I think TechT makes one...no idea if it works or not though.

Out of curiosity: What attributes are you hoping to improve?

This is the real important question

[w3ki11suckers]

efficiency and reliablibility. not looking to use it a ton since its a limited run. if its going to cost me like 100 for a 20 year old bolt, ill keep it stock ya know?

[Frmrspec]

If it was me… only thing I’d do is mod the bolt for a soft face and call it a day. Maaaaaaayyybe look into custom detents since modern paint is so small but that’s a bit more “iffy”

there was a techt bolt for matrices that basically gets rid of the need for an LPR and turned the system into a blow forward (think ion)… made it really quick and reeeeeaaally low pressure but did nothing positive for efficiency

what are people doing to mod these for a soft face if you don't mind my asking?

Most bolt upgrades for the Pm/dm series are downgrades... More so with the early 2000's ones.

Believe it or not best bolt upgrade was the hose mod. Hybrid sold a metal version. Basically it took some volume up and made them use less air

Ahh yes... VRM. This is the best option.

I forgot about the hose mod, also the Top Hat mod that just used electrical tape to do something similar. I remember reading about them when I was trying to get my PM6 up and running again.

Basically the same thing

Cheapest & best:
- hose mod if you need efficiency and
- run 050 duro buna orings on the 017 positions. This will decrease friction / lower LPR, same effect as BW bolt/polishing.
- run 050 duro on the sail or tail too if you like, it will help but I found these positions a bit less reliable/effective. Don't do the 014, it's prone to blowing out.

BW costs too much, L7 is a totally different bolt. The fuse bolt really is a robust design

i see someone on ebay has a dm11 soft tip bolt in theirs. i guess thats a easy little ugrade to be easier on paint?

You can run a DM9-11 bolt, but you basically need to buy a full assembly because you need the DM bolt, tophat, and backcap. You use those with your PM can for the setup to work in a PM5-7.

amazing info. thank you!

Hello All,

I installed a Dm9/10 bwing bolt in my Pm7 with the Pm7 can and DM9/10 back cap. The bolt protrudes into the breach a bit. I know that this can be remedied with an oring on the back cap by the threads but does anyone know offhand what size and duro works well for that?

EDIT: looks like a 017/70 might have done the trick
