Questions & Answers
does this come with and endplate and castle nut Expert Answer

No, this is a fixed stock so a castle nut and endplate are not needed. Those are only required for adjustable carbine and pistol setups.

WHERE ARE THE INSTRUCTIONS Expert Answer

Instructions are as follows:
Screw the buffer tube into the back of the lower receiver until it is tight against the receiver. This should hold in the buffer retention detent inside the receiver.
Slide the stock over the tube, making sure the takedown pin spring and detent stay inside the rifle. Secure the stock to the buffer tube with the included screw.
Insert the spring, followed by the buffer into the tube.

Good save the buffer guts, & loose mate on lower. by Spic, November 19, 2019
Works fine. Only negative is the crude buffer guts, by that I mean weights not cut square , surface rust and thin rubber spacers compared to other my A2 buffers. Good for the $. I will spend the extra 10. Next time.
