When you say new, lik how new? When was the change made? How can you tell which is which?I picked up 1953 production 336 in 3t Rem it is sweet to shoot and works flawlessly.
It if your looking for a 357 rifle look at a Rossi 92 the new ones are much better then the older Braziltech since they retooled the factory.. I changed the springs and stoned a few part and she's slick as greased hog.
