Ncstar Ar15 Barrel Nut Crows Ft Tool$15.99
Availability: In Stock
The NCStar AR15 Castle Nut Crows Foot Tool is a simple, purpose-built wrench for installing and removing castle nuts on AR15 and M4 telescoping stock tubes. If you build, maintain, or customize AR platforms, this tool makes the job faster and more reliable than improvising with pliers or screwdrivers — and it protects your castle nut and buffer tube from damage in the process.
Built from steel for durability, this crows foot wrench fits both 1/2" and 3/8" drive sockets, so it works with the ratchets and breaker bars already in your shop. Whether you're adjusting stock fit, swapping furniture, or doing a complete stock tube replacement, having the right tool means the job goes smoothly without stripped fasteners or marred finishes.
At just 6.7 oz, it's light enough to toss in a range bag or maintenance kit without thinking about it. A solid addition to any AR builder's toolkit or the bench of anyone who works on their own guns.
