Detachable Barrel extension?

[GraveRobberXL]

I was looking at this http://www.airsoftgi.com/product_inf...oducts_id=1627 and this http://www.ascarmoury.com/product_in...roducts_id=307 Does either one actually extend the barrel without the use of an extended inner barrel? i know supressors normally cover an extended inner barrel but from the short description on the site it seems that these actually extend the barrel. I wouldnt think this would be possible since there would be a gap in the two inner barrels where the supressor screws on since the inner barrel doesnt actually go to the tip of the threaded section of the outer barrel. i did a search and from what i saw noone has said anything about a supressor actually extending the inner barrel.

If these dont extend the inner barrel is there anything that extends the inner barrel that would be easily detachable (like a special supressor) or something like that?

It DOES extend the barrel...

... it extends the OUTER barrel.

The inner barrel stays the same length, so accuracy and velocity are affected in no way whatsoever.

There were some suppressors in the past (4+ years ago) that extended the inner barrel... but all of them worked so horribly that they were all taken off the market.

Thanks Illusion, I was hoping there would be something detachable if i wanted to use the same gun for CQB and longer ranged shooting
