I have a new Stag A2 butt, first time I opened the trap door the latch launched into low earth orbitFirst time I've seen that. I bought it from Rainier Arms and they sent me a new door assembly with out question. The stock body is pretty nice, the butt plate fit could be better. The body has the solid yellow expanded foam as a filler.
I have a new ArmaLite take off from a AR-10, same stock as a AR-15. This has a nice fit but you can see minor changes in color flow, it's OD green. This has a white nylon storage compartment and the rest appears hollow, not 100% sure as I haven't removed the compartment.
On both you can see and feel a line where the body leaves the RE section of the stock.
Neither is near as nice as my old A1's.
