7 inch carbon I'm really happy with the 7 inch carbon fiber hand guard it exceeded my expectations of look an feel once it was on my pistol build. Shipping was on point too. May look into getting a second one for my 9mm upper.

Sold me blems but whatev Ordered 2 G19 slides. Website showed they were in stock but it took 10 days before they shipped. I tried contacting Matrix Arms via their website contact form and also by phone but received no response. When I received the slides the DLC finish showed blemishes on both. Not gonna bother reaching out to them. I'm using a kagwerks slide release which will mar the slide anyway so whatever, gun still looks good.

Great team working at Matrix Great team working at Matrix, awesome quality and will definitely buy more from y’all in the future!

I purchased blems and non-blems but all had BLEMS I purchased blems and non-blems but everything I got had blems on it, I bought 80% lowers from you before and was very happy, that's why I purchased more from you, but this time I was very very disappointed. Will not buy again.

Awesome product Placed order and it arrived within 3 days, that is unheard of, typically takes 3 days before packages ship from most places. And the quality of this pieces is top notch
