Authentic LMT for a great price! Super sweatshop fast shipping. Loved the Ramen and constitution. Great company that I will be looking to purchase from in the future.

Love this barrel to go with my MRP upper. Barrel has some heft to it which is nice to balance. Like everything else, product shipped super quickly and packaged very well. Will be again in 556

Awesome service and super fast delivery. Item shipped the next day. Can’t believe this LMT 300 barrel was in stock. Kicking myself I didn’t order 2. Thanks Rooftop! I’ll be back.
