2022年7月4日 · Considering getting another KP15 lower to turn into an SBR once I break it in with a rifle upper. Debating over say a regular ADM lower. I absolutely love it, it's very balanced with my 10.5 inch upper. From the bolt release forward its 14.5 inches and from the bolt release back its 14 inches so it feels very good in your hand.

2021年12月21日 · The major standout of this build is the complete KP-15 SLT/Ambi polymer receiver from KE Arms. Featuring an integral A1-length buttstock, the KP-15 addresses a common weak point with other synthetic receivers — namely, breaking right where you attach your receiver extension tube and buttstock.

2021年6月6日 · This one took a little tuning, but it's a great, handy shooter. Wolf 12.5" piston upper on a KP15 polymer lower from KE Arms, modified for shorter length of pull by Echo93. This one balances very and handles very nicely.

2022年1月21日 · I'm going to register it as one of my SBRs as most of my ARs are SBRs and I'm short a lower or 2 for SBR uppers. Not flimsy at all. Stronger than a standard AR at specific points. I have to say get one or five bro! I got one for my first rifle and I have to say I love the monolithic polymer lower K. E. Arms puts out!

2024年11月10日 · I've got 4 300BO carbines, 2 are SBR's. One of the SBR's is suppressed and the sights (green dot & backups) are regulated for Sub-Sonic loads. I don't recall ever having any of them failing to function but I tend to run the uppers well lubricated. BCA is known for iffy uppers, some work others not so much.
