    After I figured the free float hand guard, it was perfect!

    Nice chassis, main complaint is that its hard to use Tech Sights with this chassis, otherwise I would have given 5 stars.

    Very please with all aspects of the chassis except for the anodizing is not the most durable finish. I knew this going in but can CereKote it myself when the time comes.

    PMACA Multi Chassis

    Posted by Robert Berry on Nov 29th 2020

    Super happy with the Multi Chassis from PMACA! It has the look I was going for with my 10/22 build and shoots .75 MOA with a Bushnell TRS-25 red dot. My Multi Chassis arrived without the lock ring and PMACA customer service had one in the mail to me within a day or two even though their website said they were out of stock. Great company to deal with.
