TELUDYNE TECH's Sine Pari Series M4 Upper Receiver

[BenL]

I have very limited knowledge about this manufacturing process (straight jacket barrel) so I can't comment on that, but based on looks alone I'd say it looks bad ass

Doesn't this gun have some stupid barrel shroud on it? supposed to help rigidity but sounds like a bunch of baloney to me.

You mean the shoulder thing that goes up?

Yeah the thing at the end that goes up

McCarthy would flip a biscuit if she/it saw that thing. Look at the size of that shroud!

No clue. Got to read into it some more before making a judgement call on the stupidity or brilliance of it.

I read into it back on ARFcom when it was originally released (or announced), and it adds a ton of weight for very little "rigidity" added or heat dissipation. Unlike the Volquartsen 10/22 tension barrels (where you can change or adjust the tension for different loads) this one is fixed so it's just a big shroud.



A SERIOUSLY more effective barrel would be a Proof Research carbon Fibre barrel for the AR15 (which they do make). The epoxies used in the barrel are heat conductive (not unlike processor heat sink paste) so not only is the carbon fibre incredibly rigid, but it sucks the heat away from the barrel liner. Of course you pay dearly for the barrel, but it's worth the performance.
