The dreaded mask / sight interference
I have been using a Tapco T6 stock on my AR 15 matched target rifle for many years. When I came across this stock for my A5, i knew I had to have it. I bought it from my local paintball store, and installed it with the T6 buttplate from my AR (I am picky about how things feel, and the buttplate helps to catch the "in between" adjustment areas, esp. when you mod the thickness like I did with mine). Instlation is easy if you have some basic mechanical know-how. I've noticed that I am getting more first shot hits with this stock (but I never had one on mine before. I went pistol style baby! lol) and the ability to lay more accurate supression/covering fire downfield.
I can see where this stock would not be well suited for speedballers. But IMO, if your using an A5 for speedball, your not going to have the best thing going (in that area). If you have problems with the hard plastic aganist your shoulder (or if you want to fine tune the length to your arms), I would get the buttstock (rubber piece that mounts onto the back of the stock). Shoot, it's only $12. And if you can't get comfortable when your shooting, your not going to have accurate shots.
