Tightbore barrels

[SSXmac]

What is the difference between the systema tightbores and the KM tightbores. Im looking on wargamers and i noticed a $25 difference, but systema is supposed to make top of the line stuff so im confused. Why the price difference, and which, if either, is better?

According to most people, the KM and the BS (Systema) barrels give almost exactly the same performance. The BS barrels are sometimes half the price, so I would recommend them.

I own a Systema BS AUG barrel and am pleased, although my hop-up has been broken since I got it (until tomorrow, when a new one comes)...so maybe I'm not one to say.

i have a sr16 withg a sytsema tight bore and the difference is really insane, (even thoughwithout any sights until tomorrow, wiat today!) i ca nreally notice the distance the bbs travel as oppose to the standard barrels. It ups your fps a little too. The accurracy range and fps will all increase a little bit/ i reccommend the cheaper of the two.

One more question, The tightbore is for my FAMAS. Systema doesnt make a famas tightbore barrel. there are some tightbores that are a little longer then the FAMAS' inner barrel and some htat are a little shorter. Would i be better off getting a longer barrel and 'sawing' it off, or getting a shorter one? or has no one ever had this problem before?

I would get a shorter one and save myself the trouble. Trying to get a smooth crown on the new barrel will be a bitch, as well as making sure there aren't any burrs left that will mess up your accuracy. I've heard horror stories of people trying to saw their barrel down and having little to no success.
