I was wonder ing if doubling can occur with both the two stage setup and single or just one or the other. I have left my fcg set as it came from RSA and want to be sure I don't have that problem when I go to the range next time, is there away to tell before if it will happen berfore I go shooting?

If you are wanting to know if it is doubling before you shoot it , function test it.

REMOVE MAGAZINE / CHECK CHAMBER / MAKE SURE RIFLE IS UNLOADED / HAVE NO AMMO NEAR RIFLE

With unloaded rifle , pull bolt carrier back , cocking hammer.

Allow bolt carrier to slam home.

Pointing rifle in safe direction , pull trigger (hammer should fall) , hold trigger all to the way rear.

Pull bolt carrier to the rear (still holding trigger) , let carrier slam home.

Look through top cover slot. Is the hammer being retained by the disconnector ? No problem.

Release trigger. The hammer should be released by the disconnector and caught by the hooks on the top of the trigger. Were they caught ? No problem.

If the hammer is not caught by the disconnector and / or hammer it is UNSAFE and will double.

If the hammer is not caught adjust your disconnector , as Campy outlined.

If the disconnector is properly adjusted and the hammer does not "follow through" during the function test then it should not double during actual firing of live ammo.

*************************************­********************************

You r-e-a-l-l-y should function test any semi / full auto before live firing it for the first time.

I had one one MISR Maadi that would have doubled (or maybe emptied the whole magazine) from the factory. Luckily I checked it before I fired it the first time as expecting a bang and getting bang , bang , or worse bang ,bang, bang, etc can be embarassing and potentially deadly.

*************************************­********************************

Once you successfully function test the rifle and are ready to live fire load one round in the magazine , chamber it and fire it (at a safe target).

Keep the trigger pulled and check to see if the disconnector caught the hammer. Did it ?

OK.

Load two rounds and repeat the test , checking after each round to see if the hammer was caught ,before realeasing the trigger.

If the rifle passes these tests it is safe.
