Completely changed the whole experience with this chassis. No brainer.
Fit perfectly. Easy to install. Can’t wait to take it to the range to try it out.
$0.00 SBR Tax stamp = fun fun fun.. CAA did great, had them in stock. Simple and easy to replace on my Gen 1 Micro Roni. Took it out and shot a USPSA match, the stock held up no issues, was sturdy. This got many looks, questions, and hands on by several shooters…
Great product super satisfied I’m glad I went with this carbine kit
