DPMS Tri-Rise Upper Receiver in very good condition. This was removed from my SSK .300 Whisper upper. The only modification from a standard .223 upper receiver is that SSK engraved The company name, location, and .300 Whisper on the left side of the receiver. Includes dustcover, forward assist and DPMS charging handle as pictured below.
Upper is large hole, I am including the small hole conversion bushing from Bushmaster.
Thanks for looking, this item has been sold.
