#TiN

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.

Welcome everyone to the 112th edition of ‘Hot Gat or Fudd Crap?’, one of our many series here on TFB. If you’re new to the series, this is where we look at the most obscure firearms that are actually for sale and ask the question – is this Gat a sweet deal or only has a Fudd appeal?  Each week the TFB staff weighs in with their thoughts, but readers get the final say in the poll at the bottom of each article.

Brownells now makes lightweight AR-15 bolt carrier groups. While the bolt itself is a standard one, the bolt carrier has been lightened by cutting and machining out the material and leaving just enough to make it functional. As a result, the new BCG weighs 8.2 ounces.

Suarez International, known for training, avocation of red-dots on pistols, and quite a few Glock components, has announced their latest release, Glock “Match” grade barrels. The new barrels are 1/10″ twist to stabalize most common 9mm bullet weights, from 95 to 147 grains.

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.
