Spike’s Tactical is a company that is well known in the AR-15 industry. They produce quality products the are made to be run hard. This Spikes Bolt Carrier Group is a excellent piece for your AR-15 due to its excellent build quality, top notch materials and low price.
As noted earlier, the M16 profile BCG has more mass than an AR-15 BCG and some feel that this can increase reliability. The rationale for this line of thinking is that since the BCG has more mass, it will have a greater amount of momentum when moving through the firing cycle. Since the BCG may have more momentum, this could possibly help the bolt carrier group to better push dirt, debris and fouling out of the way to enable your rifle to continue firing. However, there has not been a definitive test to demonstrate this difference in reliability
One of the best parts about Spike’s Tactical products is that they have a pretty cool logo. This Spike’s spider logo is laser engraved on this bolt carrier group. The laser engraving is located in a position that makes it visible through the ejection port for your viewing pleasure.
Spikes Tactical has used very high quality materials in the manufacturing of this component. The Bolt carrier is machined from mil-spec 8620 tool steel. The carrier key assembly is formed from mil-spec tool steel. The bolt is precision CNC machined from Carpenter NO. 158 steel. Tool steel is also used to make the extractor.
To ensure enhanced durability, the bolt is shot peened, which is current military specification requirement. To ensure that every Spikes Tactical bolt is high quality and will not fail you, each individual bolt is individually high pressure tested (HPT) as well as individually Magnetic Particle Inspected (MPI). This helps to ensure that the bolts are properly manufactured without any hidden defects.
