I've had 7 in the past and several have just sat... since then i've sold them and only have the following:

1. 11.5" BCM SBR w/ BCM KMR Surefire scout Aimpoint micro (my goto rifle)
2. SCAR 16 pistol with Aimpoint Micro
3. Noveske 16" SS Barrel NSR with Burris 1-4
4. Pistol 10.5" plain jane iron sights w/ M4 handguard

All are outfitted with AAC brakes and can be suppressed when my Stamps are approved.
