I am interested in a DCM legal upper, or parts to build an upper, or a complete rifle. I currently have a nice Bushmaster 16" Dissipator model. I would like to trade or get a good deal on buying outright these parts, am trying to get into service rifle competition, don't have much extra money at the moment, let me know if you have any other competition equipment(spotting scopes/stands, mats, gloves, etc.) thanks a bunch!!
