I just recently purchased a New M1A with a fiberglass stock and I took the action out of the stock to put a sling swivel stud on the for end of the stock (there was already a hole there and bought a kit that would fit in the hole and such) I put the action back in the stock and the front part of the stock is springy so to speak where it was solid before. I have talked to comp shooters and they tell me that a M1A shoots a whole lot better. My question is how do I get the springiness out of the front? I don't know if I have to Press it into the stock or put filler up front? I'm a machinist by trade so complicated stuff isn't hard to explain to me and besides learning to be skilled when it comes to working on one appeals to me. Any info would be great.
