Spec

Getting Tabitha ready for the arrival of the purple stock set from Cavalry Manufacturing.

CavMan is the least communicative and slowest shipping gun parts company I have ever dealt with, by the way.

Cav doesn't offer the purple stocks in mil-spec.  I had two commercial-spec carbine receiver extensions (aka buffer tubes) from Del-Ton in the parts bin, but they're far too long.  Additionally most commercial extensions have a slanted back end.

Note the angle.

So I ordered a replacement extension from Brownells.  High Standard brand.  The Q&A section indicated an OA length of 7.2" so the "way too long" would be taken care of.  Well...  As you can see in the above picture, it's closer to 7.75" OA.  Proper mil-spec is 7.188" long.  It's also identical to the Del-Ton tubes it's meant to replace.

So I enquired of Arfcom's Retro Section.

The UTG-TLU004 fits the bill I was looking for.  Except for diameter and materials it's a mil-spec buffer tube.  Mil-Spec should be Ø1.15" and made from 7075-T6 aluminum.  Commercial is Ø1.17 and is normally made from 6061-T6 aluminum.

Now, if Cavalry Manufacturing will get off their butts and ship the "we have plenty in stock" purple stock set my readers were generous enough to pay for, we're golden.  Or purple.  Or something.
