Ok Im a timmy poppet guy but I love how quest shoot for a spool
so here are some of the Mods I made for my quest
1st I drilled the HPR reg bottom cap with the smallest metal drill bit I could found on home depot
screw the cap all the way
mark with a sharpie
unscrew it
always drill in the spring section
2nd I drilled the LPR with the same above
3rth I used a plastic cap you can use a standard pen cap, I used a dental syringe cap and didnt have to cut anything
meassure it and check if it dosent goes further than the bolt tip
drill a hole on the tip and fill it with JB WELD
then I Buff the tip of the bolt guide and use JB WELD to join them together
4rth I cut some air hose and then I start adding inserts untill my FPS start to drop
or
you can get this at walmart for 5 bucks

I cleaned with acetone the bolt pin
leave the o rings
mix a small amount of paste and do the cones near the orings
after it cured for 3 minutes "semi firm" take out the orings and clean the groove
mix a small some more and add in the middle
let it stay for 15 minutes
lube o rings and chorno
if U add too much just sand from the middle
if it chrono HI you can clean with acetone the middle and add some more
this is the final result after sanding till got the correct FPS
the draw back is that I cant use a GM bolt because I tune it to a stock bolt
so if U tune it to a GM bolt prolly you will need to add
if tuned to a stock bolt and want to use a GM you will need to sand till you get the FPS
what do I get from this?
well the holes boost the recharge rate and the stock reg can go head to head with a AKA or a 360 reg
The LPR gauge pin will only move 15 PSI of recharge
FPS are tighter
you can go lower LPR cause its recharging faster
Im got a extra pod than than hose mod prolly same shots like the 4b new bolt , I think because you fine tune it with the sand paper
the hose mod is better than the tape mode because it never peel off
the no rollback tip will give you a 10 FPS boost & the paintball wont rollback to the bolt hole
I hope this helps and one day goes a sticky
