I use G&P compression parts and they do great. Only thing I would recommend is to polish the cylinder and you're good to go!

 

Do you already have the parts or are these things you're about to order??

 

The hs5 m nubs work the best i think. Also those compression parts seem legit, as long as you get a perfect airseal, nothing will beat it.

I'm not sure if I am allowed to link to another forum, but there is a guide to perfect air seal using anaerobic gasket maker. PM me.

Plan to order these soon

Well all your parts are pretty good. What are you trying to achieve with this set up??

 

An m110, 13:1s and a gt40000 will get you pme no doubts

Around 400 fps and around 30-35rps

 

Around 400 fps and around 30-35rps

Your parts will get you there, but you're gonna get PME with that spring.

 

Wow i was think the same set up, im trying to achieve the same results

 

Like i stated before an m110 will definetly hit pme. On that setup expect about 375 fps and 37-40 rps. I would use at least an m130 then play around with port sizes, your airseal wont matter with an fps goal of that and a spring of that size

Airseal always matters. A consistaint airseal will get more accurate shots. He's r-hopping the gun so I assume he wants an accurate gun. Airseal is importaint.

 

I predict roughly 43-45rps with those parts. PME will definitely occur if the spring is only an M110. Lonex compression parts are excellent, but don't forget to test compression and do any necessary mods.

I didnt say airseal was not important, airseal is one of the most important components to making a gun reliable.

If you recommend an M130 should I also get a new gearbox shell? Also, with an M130, should I change to an aluminum piston head?

 

A new shell isn't necessary until your getting up to an m190 and even then most shell will handle it for a little bit, also for the piston head, i would stick with a poly carb because you are going to want the lightest piston assembly as possible

What about the modify cylinder cylinder head and piston?

 

Would swiss cheesing the piston be a good idea?

 

Yes, its not a bad idea, i makes your piston lighter which increases return time and removes the vacuum of air when the piston is being pulled back.

Okay, sounds good. I'll update this when I eventually get all the parts
