Ok folks. Who can help me shorten mine? Darn thing is out there lol... MP15 Sport.

I took mine apart and just decided to snag a vltor re-1 buffer tube and a CTR stock. Its easier and less of a headache. The fixed stock that came on my MP15 wasn't adjustable it just looked to be, so one I took it apart holes would have needed to be drilled and what-not and I am too much of a perfectionist when it comes to my guns for all of that noise.

you can on some models just remove the pin that holds the unlock mechanism hence the lock will not raise the spring and the stock wont move. and this can be make stock again if you move to a free state or need to change the length
