15-22 after some basic additions...
Doomsday Tactical Charging Handle
UTG Red/Green Dot (and 3x, not pictured - both from Gunny4503 here on S&WF)
Magpul MBIS
Magpul Enhanced Rail Panels, although I need to shift the rear pair to the forward position.
Magpul MOE Grip
Houge Overmound Grip
Spikes Can (arrived today!

)
CrayolaMod

.
Still trying to decide on sling options...not really a SP fan for general use, so will most likely run a simple Blackhawk 2P sling, just need to figure out what rail attachment I want to use, simple UTG or MOE rail or other...? Have Magpul STR on my S&W AR and may add one here also, or possibly a Bravo B5. Then some JP Yellow springs and I
*might* be done lol.
