Most of the forged 7075 T6 lowers are made from Cerro forgings and are CNC machined to M16 blueprints with the exception of the auto sear hole, and the trigger group area which was changed to make it more difficult to install an auto trigger group. Sabre Defence changed their logo lowers and uppers by moving the connecting pin holes .001 to make the uppers and lowers to fit tighter, and the upper and lower were hand matched and fitted. Some manufacturerd make these small changes to provide differentiators to try to seperate them from the other manufacturers. This is done to try to make a higher profit margin.
