Trapdoor buttplates and the like?

[quepasakimosabe]

I am building my second rifle, the previous being an AR-15, was pretty straightforward. I picked up a Stevens 200 in .308 and like 99% of the others am throwing away the plastic for a Boyds laminate, trigger, and when Pacific Tool and Gague gets off their bum a drop in fluted bolt body (why...beacuse I can). Eventually the barrel yes but not for a bit. Anyways, I have found all the items i want for the rifle online and managed to procure them or plan to shortly except this.....

Awesome, that is just what i was looking for. 150$ is a bit pricey for a hinge and some metal but at least it is already a smooth surface to engrave on. Thanks again for the help.
