Do you want to find out if your just as good parts are actually just as good? Are you trying to squeeze every last bit of performance out of your rifle? Are you unsure if your super wobbly BCG is out of spec? I've got the tools for that! Listing if anyone want to borrow these instead of buying a set for yourself. Just pay shipping and a deposit to disincentive stealing, and you're welcome to borrow any or all of these. I have a 3 bore gauge set for BCG efficiency, firing pin hole diameter gauge, cam pin hole diameter gauge, and 556 headspace gauges. (If you really want, you can ship your BCG and barrel/upper assembly to me and I'll check the specs for you and return it)
You pay shipping, and a deposit that I'll return once I receive them back. (Please don't steal my gauges)
