I'm putting together a 300blk PDW , just a very basic build , just because , nothing fancy and have a few questions for those in the know about this .

1) Muzzle break , I like the old school A2 , or do I need anything special to run this with a 7.5" barrel ?

2)The gas block , is there a 300blk one or just any 5.56 one , this will have a pistol length gas system .

3) The BCG , what weight does the BLK like the most or does it matter ?

Thanks in advance .
 
Any gas block, but you may want to drill/mill the gas port, depending on the ammo. The BCG depends on the ammo. A linear comp may help, depending on the ammo.

1. 5/8" x 24 thread (308 brake)
2. standard gas block
3. ran both semi and full bcg (standard and T2 buffer)
I run 9' barrel , I have no problem running 110gr o 230gr (depending on powder)

Ditto on my 10.5" DD upper. I haven't started mucking around with subsonic loads. Everything ran/fed like a champ.
