I want to increase my new GBB LM4 PTR fps and want to start with the simple steps:

- Inner barrel (I would love to use 6.01, can I?? which brand?? barrel length?)
- [barrel extension] or suppressor (Brand? length?)
- Suggestions

Thanks

A tightbore barrel for the lm4 does not exist at the moment.  Edgi is working on some or look up boobies mod for changing out the hop up to use a ksc barrel.

Only options to increase fps is a rocket valve mod which is also in the forums.

Welcome to the forum. You can use any barrel extension can as long as it has CCW threading. As for TBB, Jonsun has already pointed out EdGi is working on barrels for the LM4, but you could possibly retrofit barrels made for the KSC M4 GBBR.
Also question, what retailer did you buy your gun at? Im only asking because I see youre outside of the US, and im just curious to where people in Europe and sorts are getting their KWAs from heh.

as far as inner barrels go, there are none yet. but as far as barrel extension's are, the surefire licensed extensions are pricey, but pay off in some serious eye candy as far as trade marks go, less expensive would be the Matrix brand, sold excessively on evike.com, which run about $30, and have some decent trades and are of a lesser build quality, but will still do the job quite nicely.
