I just SBR'd my home piece- LMT Defender 2000 pistol in 300 AAC with a sopmod stock, LMT vertical grip, EOTECH, Cloud Defensive REIN light, YHM Phantom Suppressor, and law tactical folder.
When my BRN-180S comes in, it's going to be my new bag gun.
Ive been looking at those brownells BRN uppers and its tempting.
