CMMG Receiver Extension & Stock Kit A1 Fixed Black Synthetic for AR-15 Review

The CMMG Receiver Extension & Stock Kit A1 Fixed Black Synthetic for AR-15 Made a Bold First Impression

The CMMG Receiver Extension & Stock Kit A1 Fixed Black Synthetic for AR-15 promised a return to classic simplicity for my AR platform. I’ve built numerous ARs over the years, dabbling in everything from adjustable carbine stocks to the latest in Magpul furniture. This kit offered a stark contrast, a throwback to the original AR-15’s fixed A1 stock.

I was seeking a more robust and streamlined setup for a dedicated range rifle. Adjustable stocks have their place, but I wanted something utterly solid and unwavering, reminiscent of the rifles I trained with early in my career. The CMMG kit, with its promise of easy installation and durable synthetic construction, seemed like the perfect candidate.

Upon unboxing, I immediately noticed the simplicity of the components. The kit included the A1 rifle-length buttstock assembly, rifle buffer assembly, and rifle action spring. The synthetic stock felt surprisingly sturdy, though noticeably lighter than some of the more premium polymer stocks I’ve handled. My initial impression was one of practical efficiency over aesthetic flair – a tool, not a toy.

I considered a few similar kits from other manufacturers, particularly those offering “mil-spec” A1 stocks. I ultimately chose the CMMG kit due to its balance of price and reputation. I wanted a dependable, no-frills option without breaking the bank.

My first impression was cautiously optimistic. The kit looked well-made, and the components felt solid. I was excited to get it installed and see how it performed on the range.
