The Hawken Doctor - Custom Nipples

I got these in the other day from a custom maker.

Super high quality!

Material Stainless Steel - European Made
Depth of thread approx 7/32
Dia. of exit flash hole approx 3/64
Length of cone 7/32

I've tried Remington, CCI and RWS #11 caps, and they all fit great.

I have not measured the flash hole size yet, but it does looks like its at least .028" diameter.

I'll see how they performance in the next day or 2 and report back.
