Better than expected for the price! by Dante Calabrese, Verified Owner, October 31, 2025
This was for a budget build that I don't plan on using for point shooting. Very good for the price. Will not compare to high end competitors but its pretty solid quality. The grey is very close to the standard sniper grey. Im happy
