The BRP gun is awesome. I've shot about 10k rounds through mine and no hiccup yet. I ordered the gun with the standard bolt originally. I later purchased the Slowfire so I could use the spade grip. I'd recommend purchasing the slow fire first, as later on the standard bolt is a cheaper purchase. Of course you can adjust the Slowfire with springs ect anyway.
I think BRP Stemple are some of the most underrated guns out there.
Here is mine, sta dated bolt drum dump
Since we are on Stemple/SW76s here is my Burgess SW76 copy made on a Stemple tube. I guess it is about the cheapest MG you can get. I need to send it off to Andrewski to have a little tweaking done.
