Cheap alternative - CMMG, Inc A1 Stock Assembly

I purchased this to replace an A2 stock on an old colt rifle of mine because I like the shorter length of pull. This product was fully functional, but disappointing. I honestly expected a lot more from CMMG. This stock is NOT a reproduction, but rather a cost-reduced look-alike. The is NOT foam core, but rather just hollow molded plastic. Theoretically gives more room inside, but it sounds hollow when I tap it. The main disappointment for me was the butt plate. The fit between the stock and the buttplate is poor with gaps and overhangs. Worst of all, the trap door is just molded plastic with a "living hinge" and a plastic snap closure that makes me think of Tupperware. I'm seriously reluctant to put anything inside because the door is so flimsy. I wanted to use my colt butt plate from my A2 stock on it, but the dimensions are so out of spec that it barely fits with poor alignment. I may be able carve on the stock with my Dremel until my mil-spec butt plate fits, but that may not work. I will keep this stock and use it, but if I could do over, I would buy a legit repro A1 stock from H&R (PSA) for just a little more money. On the plus side, my stock DID come with an A1 length screw. I bought one separately because I read that this stock did not come with one, so now I have a spare, I guess.
