I am hoping that someone can explain a couple of arsenal marks on my Plainfield M1 carbine. I have a triangle with a P in it on the barrel a R.I.A. on the front site and a large M on the mag release. Trigger and mag housing is an exact copy of the GI trigger housing except in aluminum.
It is not the Universal aluminum ones but a direct copy of the GI. anyone ever heard of this? It shoots very well and has a nice crisp letoff.
