boofstien Posted May 1, 2013 Share Posted May 1, 2013 Hi all I picked up my ICS m16 in 2006 and from the box it fired around 290 fps No idea what spring it has?. Long story short I used it for a couple of weeks when i got it and used around 2000 rounds plus and since then it has been doing nothing for 6 years so i had it serviced and greased etc prior to a skirmish on sunday. I have just installed a madbull 6.03 509 barrel and I want to get it firing around 335 340 to allow for chrono tollerances (my sites absolute upper is 350) Will an m100 spring be of any use? CheersBoof EDIT: Also ive lost the brass ring that slips over the barrel and keeps things in place on the hop. I was hoping the madbull came with one but didnt so ive used a little rubber washer. Does anyone know where i can find a replacement. Ive tried googling but im not 100% sure what its called. Link to comment Share on other sites More sharing options...
Supporters sp00n Posted May 1, 2013 Supporters Share Posted May 1, 2013 springs will vary from manufacturer to manufacturer, i used this when selecting a spring for my project MP5. however i have no data on what gun/ammo was used etc so these are only ball park figures and should not be taken as 100% for every gun etc. as for your lost bit, have you tried giving a ICS dealer a call? i think land warrior are a dealer again.

boofstien Posted May 1, 2013 Author Share Posted May 1, 2013 Thanks for the guide mate!, I think I will go with guarder sp90. As for the lost bit, on closer inspection of the manual it looks like it never actually had one but instead had a rubber washer that fit a grove in the barrel. I just need a generic barrel spacer i believe but cant find one anywhere in the UK. I have found a set on ehobby asia and may have to get those.

I have the sp100 in my project and it chrono'd at 300fps but I did have the cylinder the wrong way round no idea what it is now though. Link to comment Share on other sites More sharing options...
