    FDE ceracoated multi chassis

    Posted by Mas on Oct 11th 2022

    I have to admit, I was alittle disappointed with this chassis. I have 2 other chassis(black anodized) that I bought over 5 years ago that were very nice. I thought I would try the more expensive ceracoated FDE for my next build. This chassis wasn't machined as well and has little nicks on it. To tell you the truth, it looks like I got a "blem".

    Absolutely amazing product. Easy to drop in standard 1022 upper reciever and modify to truly make a one of a kind.

    This chassis system is phenomenal! I’ve bought 2 so far and I’m looking forward to buying and assembling more 10/22 setups chargers and rifles.
