It's GOOOOLD! New Luth-AR Titanium Nitride Coated (TiN) AR-15 BCG

Titanium nitride (TiN) coating is wear-resistant, inert, and most importantly for firearms – reduces friction. While TiN is most commonly found on cutting tools, punches, dies and injection mold components for improving tool life, it’s also used in the firearms industry for many of the same benefits but it’s often cited as making firearms withstand the normal wear between sliding firearms components. TiN coatings are also notable for being extremely thin compared to some other durability coating methods and thus it’s often used as a purely decorative finish as well. Luth-AR has just announced the introduction of their new TiN-coated complete AR-15 Bolt Carrier.

TFB Armorer's Bench: Complete AR15 Disassembly - Bolt Carrier Group

Welcome everyone to the TFB Armorer’s Bench! As mentioned in the little blurb, this series will focus on a lot of home armorer and gunsmith activities. In this article sponsored by  WheelerTiptonCaldwell, and  Frankford Arsenal, we’ll show how to completely disassemble an AR15 bolt carrier group. I am well aware that most of the folks who pass through these parts are into the new, cool, and tacticool. I personally love older and obsolete stuff but I also like to take things apart and put them back together. That being said we here at TFB thought it would be nice to have a resource available for disassembling and assembling an AR15. Smith & Wesson was gracious and kind enough to help us out and sent us one of their Sport II models. Now we are back to it folks! Took a nice little break over Labor Day weekend and now we can jump back into our disassembly articles on the AR15. This one is sort of a special intermediate article focusing on the BCG (bolt carrier group) and charging handle that would be removed from an AR15 upper during cleaning or disassembly. Let’s dive right in!

Review: Iron City Rifle Works Tactical Advantage BCG

Right after we announced that Iron City Rifle Works was offering a new Tactical Advantage line of bolt carrier groups, they reached out to Phil to arrange for testing of the new design. I selected the C4V coating for no other reason than it is a great looking finish. The C4V coating also has some other benefits past being good looking that we will get to later.

New Iron City Rifle Works Tactical Advantage Bolt Carrier Groups

I will admit, prior to this press release being emailed to me I was blissfully unaware of Iron City Rifle Works and their products. Every now and then even though I try to stay pretty in tune to what is going on in the shooting sports world a manufacture somehow hides from me. Now that I have had a chance to look over Iron City’s inventory, I think I am going to have to part with some money as soon as they get that Copperhead bolt carrier group back in stock.
