Re: CBRPS Mosin Chassis
I didn't own or shoot this thing, so I can not answer your direct question.
But here is my take - cosmetically, I do not like it - looks bulky and heavy to me, this design uses lots of material with no clear function behind all this construction. If it was slimmer in general, it would probably look much better.
Functionally, it should work fine - I've built alum. bullpup stock for MN around 1995, and it proved to be a good platform. CBRPS uses the same concept, so I feel it's a healthy approach in general.
Leaving MN barrel in full original length hanging like this was kind of shown not be a good idea from accuracy and consistency point of view. Of course, barrel length is not CBRPS business, so you always have a choice here. I'm confident that short barrel should provide better results.
But if you like it, don't hesitate and get it. It's your money.
