Battle Arms Development Enhanced Pins Set Titanium
*** Click on a photo for ordering info and pricing *** Description: Battle Arms Development Enhanced Pin Set (BAD-EPS) just got better! Now available in natural machine finished Grade 5 Titanium (BAD-EPS-Ti) it is approximately half the weight of the steel BAD-EPS. The BAD-EPS-Ti is perfect for those looking for a lightweight build, competition, or simply seeking the raw titanium finish appeal. Each BAD-EPS-Ti (Enhanced Pin Set - Titanium) set consists of one BAD-ETP-Ti (Enhanced Takedown Pin - Titanium), one EPP (Enhanced Pivot Pin - Titanium), two springs, and two detents. Precision CNC machined from Grade 5 Titanium. Features: AR15 Compatible - fits all AR15 lower receivers with mil-spec .250" diameter front pivot and rear takedown pin holes. Patent Pending Pivot Pin & Takedown Pin Head Designs - greatly improved gripping surface and pull strength without the use of oversize heads. Low Profile Pin Heads - low drag and never in the way. Lower profile than mil-spec pin heads. Ambidextrous Safety Compatible - the BAD-ETP-Ti (Enhanced Takedown Pin - Titanium) head design does not obstruct the use of the right side ambidextrous safety selector lever. Extended Pin Tips (+0.030" over mil-spec) - added tip length noticeably aids in starting/pushing the pins out from the left side of the receiver, without undue protrusion. Bullet Tip Guide - cone shaped recess at both pin tips prevent accidental bullet or tool slip and reduced the chance of scratching/damaging of the receiver. Patent Pending EZ Guide Channel - Additional EZ Guide Channel and detent hole makes it easier to locate the detent and ease the installation of the BAD-EPP-Ti (Enhanced Pivot Pin - Titanium) to the lower receiver.

I like the functionality of the larger head and .030 longer pin but it's too much bling for me, fortunately for me they make it in BLACK.

There is a process where titanium can be made black. Unfortunately it is secret formula that some jewelry maker controls. Or at least they did a year ago when I searched for a way of turning titanium black. I work in ti quite often and ti pins will work just fine there is no reason to fear galling as nothing is moving around the pins with any frequency. |

Most colors by anodizing. No big secrets, but some colors require a lot of voltage. I can probably find out more from some people who sell Ti for architectural uses.
http://www.titaniumfinishing.com/page09.html I know the American Express Black Centurion card (its Commercially pure titanium) is black anodized, then laser etched for the lettering and scrollwork. It was interesting to see - The back is milled out for the magnetic strip as well as a little pocket for some sort of chip or RFID tag. I don't know who anodized it, but I do know who made the titanium but the only one I've ever seen was just the sample from the company. Some time back I helped the architectural people get a dark matt surface finish for titanium roof panels for a home near boston. That was simple as we just had the coils grit blasted. The roof had to be non reflective since it was not far from the airport, or approaches. I have heard that another gun manufacturer was able to get a near black on titanium parts by accidentally heat treating Ti in I think a nitrous atmosphere (i don't think straight N2). I will see about making some other contacts to see if the person who was involved in that can say more. And I work with titanium every day. |

Anyone have a weight on the takedown pins? Lighter than the V7 set? Also, any weight savings on the detents and springs? 3 oz http://www.revolvr.com/new-bad-enhanced-pin-set-titanium.html |
The weight of the pins are (per our shop scale):
  We will be releasing the Titanium version in BLACK soon but we are completely sold out of the natural Titanium Pin Sets from the first production batch and the next two shipments are already spoken for. Soon as we are able to catch up with demand we will have the black finish version available. Thank you. George |

Quoted: Will Ti take Duracoat,Cerakote, Krylon? Would look good in some camo colors. Anodizing or PVD are options that will not impact the tolerances much. You can also heat treat the titanium to have different multi-colored effects like we were doing here for fun on the lightweight prototype rifle.  |
