While doing some trivial yet unimportant research online I came across the following company. Evidently, they’re a spinoff of P&S Products/Molding Solutions (who are a DoD contractor for M4/M5 rail systems and rail covers). Anyone familiar?:

Their Ti-7 Stock is my favorite SOPMODish stock. I have a couple, one on the rifle I shoot most often. I cant say I’ve abused it, a couple of minor drops, etc., but it has held up well.
That is the only product I have from them. No problems with order and shipping.
I as well have a Ti-7 stock, good quality. Colt released a carbine a while back with a “colt” marked Ti-7 stock and Exos trigger guard.
