|TacStar AR-15 Tactical Front and Rear Grip Set Black|
I also like the price! The set was only $40. I got these here at www.cheaperthandirt.com.
The JR Carbine accepts standard AR-15 furniture so the selection options are great. I also like that the front grip folds down neatly.
The pics below show the before and after.
--Next up I need another EOTech!
