    1. Good overall experience

      Shipping was fast, product came wrapped very well and pre oiled. Havent gotten to shoot it just yet but it fit perfectly with no issues. The bcg looks like it will be of good quality. on 10th Sep 2020

    2. Mystic black

      Best coating I’ve ever had on a bcg. Great costumer service, got my bolt ordered and delivered quickly. on 4th Sep 2020

    3. Excellent product

      Runs super smooth, cleaning is a snap. on 3rd Sep 2020

    4. Easy like Sunday morning

      very satisfied with entire ordering process. Couldn't be happier. Customer service is amazing. BCG's are great and exactly what I wanted. on 2nd Sep 2020

    5. SLICK

      Hello this is Darren Frazee rtcustom guns I just want to say to that species years phenomenal it's dry to the touch but it feels wet in the hand unimpressed we'll see how it does the next few thousand rounds. on 28th Aug 2020

    6. Best of the best.

      Couldn’t be happier with mine. Amazing product, quick shipping and awesome customer service. on 25th Aug 2020

    7. Exactly as advertised.

      Amazing product, amazing quality. 10/10, would buy again. on 24th Aug 2020

    8. Mystic blue not really blue

      Purchased 2 mystic blue bcgs and both of them are black Not blue their customer service is great They confirmed the first bcg was indeed Mystic black so I chose to keep it second time received a black bcg again it is definitely slick and shiny just wanted something with color since blue is one of my favorite colors Disappointing on 20th Aug 2020

    9. Work of art.

      This BCG is so nice i want to wear it on a chain! Runs super smooth and easily wipes clean with a rag, far easier than even my other nickel boron BCG. No more disassembling, soaking and scrubbing after everytime i want to go shoot.
      Cant wait to get the lightweight one in the black coating for my lightweight 2 gun comp rifle. Hands down the nicest BCG on the market! Just wish i could afford one for every rifle.

    10. Hands down best BCG you can buy.

      If I could give this 10 stars I would! Far superior than any other BCG I have felt or shot. Fires flawlessly and can basically be cleaned by the wipe of a towel. So impressed I’m about to order another 9mm BCG. on 10th Aug 2020
