I say the FCSA the best of the 50 forums, That isnt saying much as they are the only game in town. They have a bunch of issues. They have tons of power control issues. They are all about shooting at FCSA matches, If you don't shoot at their matches forget it, you are scum and have no rights, you cant vote, and your words only fall on deaf ears. The BOD is mostly influenced by old members that are all match shooters. The forum is run by One guy that was appointed by the BOD. The FCSA wants zero change, they are happy with the way things are, so If you join and are willing to fall in line they will play nice. Don't expect to find a bunch of tutorials on all the secrets they have, all the good info is well guarded and they want you to pay for everything. Any info that you find in most forums how to's, DYI's they put it in a MAG that if you want to pay for back issues there is some good stuff. I for one have been hugely disappointed in the FCSA. On a good note for $40.00 you get a quarterly subscription to the mag and a list of vendors. I asked my friend to make a free open forum dedicated to the 50 bmg rifle, so he did. All the latest features a forum could want and its free, check it out at the bottom of the board Look for the The "Free" 50 BMG Rifle, Open Forum, It's there we will see if people are really wanting a free forum for the 50
