SCAR DMR project

[daniel gill1]

hi guys

im planning to turn my TM SCAR into a semi-only DMR rifle. ive got most of it figured out already, but i do have a question about the barrel (and general accuracy upgrades). does this rifle use a specific barrel, and what would be the most logical one to use for this upgrade? (no ridiculous prices please). and is there anything else i can do that is fairly inexpensive to upgrade its accuracy

thanks everybody
