Thanks (and to teratos, as well). My concern is that the CCS - like the Troy PDW stock kit - has a shorter stock, which can decrease the OAL. But one way or another I will make this all work. Much obliged for the feedback.
The CCS takes about 2.5" off the OAL. You would probably need a 12.5" or maybe a 10.5" with pinned/welded muzzle device to meet 29" min OAL
