Spikes Tactical Ar-15/m16 Bolt Carrier Group Nib Review

I have been shooting the AR platform for over xx years and I only recently decided to try out a coated bolt carrier group (BCG). There was a ane-mean solar day coupon at Brownells and I was thinking of random things to become and ended upwards ordering the Spike's Tactical Nickel Boron BCG.

Traditional AR BCGs employ a (manganese) phosphate stop coating, also referred to as parkerized. This terminate is actually quite resilient and is a adept coating for steel to foreclose corrosion and to provide lubricity. This is why it has been used on military machine service rifles (M1 Garand) and has been used on many production guns (due east.g. Remington 870 and 700 police models).

Only some manufacturers experimented with alternative coatings to promote the concept of having a BCG with a blanket that is harder and has more lubricity than traditional phosphate for better role and easier cleaning / maintenance.

Chromed commodities carrier groups were some of the first culling BCGs to be released. And then came Nickel Boron (Nib) and later on Titanium Nitride (TiN). Alternative coated BCGs often carry a higher price tag compared to phosphate BCGs of the aforementioned manufacturer, oftentimes 25% higher (or more than).

The debate has always been, do BCGs with alternative coatings provide more reliable role, do these BCGs make for easier cleaning, and is the increased price over a traditional phosphate BCG justified?

Anyway, my xvi″ midlength rifle (and 18″ SPR) has a Spike'southward Tactical phosphate BCG, so I've already been using Spike'due south Tactical BCGs for awhile now.

Thus, I ended up sticking with Fasten'south Tactical in my dabbling with a non-phosphate BCG, which is nickel boron, as indicated before.

A NiB coating is supposed to reduce friction between 2 metal surfaces and as well help dissipate heat faster.

The unabridged BCG every bit shipped is nickel boron except for the cotter pin (the pivot that retains the firing pin in the carrier). If the inside of the bolt carrier is non Bill coated, and so I assume it is chromed.

Important: Always check headspace whenever pairing upwardly a commodities and butt that have not been used together before. Headspace gauges are very cheap, and can typically exist had for $20-$25 per estimate.

Afterwards 300 rounds at the range, the new Neb BCG functioned perfectly fine and the burglarize didn't function any unlike than with the previous phosphate BCG.

As far every bit cleaning is concerned, cleaning the Neb BCG is easier than cleaning phosphate, but non by much.

After wiping down the NiB BCG with a disposable shop towel (with no liquid cleaner), most of the grime wipes off easily, only the areas where hardened carbon fouling builds up, specifically the bolt tail, nonetheless requires scraping.

So even with a Beak coated BCG, you withal demand to utilise some annoying cleaning (eastward.g. nylon brushes and MPro-vii) and a scraping tool to get some of the hardened carbon build upward off the BCG parts.

With these observations, would I recommend a nickel boron coated commodities carrier group over a regular phosphate BCG? Not actually.

A NiB or other culling coated BCG is probably the last matter to think most when putting together your AR. Getting a high quality BCG is obviously a priority, just there are plenty of reliable phosphate BCGs out there that will serve yous well. Spend your money on a better trigger (eastward.g. Geissele) or on quality optics / sights before going with a Beak, Tin, or other specialty coated BCG.

But even if you have the actress cash to spend on a coated BCG, don't expect it to provide y'all any huge differences over a standard mil-spec phosphate BCG. Cleaning won't exist all that much easier and you'll even so need to lube the BCG for proper function.

So in summary, you can forgo a nickel boron, titanium nitride, or other alternative blanket commodities carrier group and you volition not be missing out on much at all.
