My 16B starts off with good accuracy until it gets hot and then the shot group grows X 3...I assume that it's due to the light weight barrel warping from heat. Is anyone else having this problem??

I don't know how many rounds or what the time frame is to get your rifle "hot", and then lose accuracy, but all firearms with rifled barrels that generate heat from friction and combustion have the problem to varying degree.

And the slimmer/thinner the barrel, the worse the effect is. My .308 BLR (Browning Lever-action Rifle) is terrible...8-10 shots and I have to let it cool off for a half hour.

Replaced the built in Bi-pod front assembly with Kel-Tec's (overpriced) Compact Forend so that I could use a conventional bi-pod. 50 yard groups, 10 round, are now about an inch and a half....big improvement...I assume that the vents in the Compact Forend allow for better cooling of the thin Bravo barrel. I rarely used the built in bi-pod, it was too wobbly...they reminded me of old venetion blind slats!! Also, have tried the HexMag 15 round (NJ legal) magazines and they function OK!!
