Instaling a Tightbore
 

Hey guys I ordered a tightbore barrel for my TM M16A2. I never done that before. Is there a walktrough on how to do it somewhere... thanks

Take down the gun so you can remove the stock barrel and hop up, remove the C clip, and carefully take off the hop up rubber, re lube the barrel and rubber, put it on the new tightbore, and reasemble.

By chance, do any of you have some tips for installing a tightbore on a G&P metal body/hop-up?

its pretty much the same

Sry to piggy-back onto this but anyone know if it is different on a TM G3 SG1?

When installing a barrel, it's almost all the same. Find a way to get your current barrel out, remove a C clip, and then if you're lucky the hop up rubber will come smoothly off your barrel, but I find that the rubber loves to stick to the barrel. You have to play around with it for a while to get the rubber to come off without hurting it. I always have an extra hopup rubber around just incase as I'm pretty brutal with take downs.

Then you insert your new barrel, make sure that the hopup hole is facing the right direction (it can only face up or down as the C clip doesn't allow the barrel to go into the hopup in any other directions) and then just reassemble the way you disassembled.

One warning, the hopup has a little, actually tiny piece of tube that pushes down on the hop up rubber. Becareful not to lose it and becareful to put it back in flat and in the right place or your hop up doesn't work anymore.


Getting to hopup and removing the barrel is the hard part.

Also, a little silicon oil helps when putting the barrel and the rubber back into the hop up unit.
