Sale! 5.56 Y/M LIGHT WEIGHT NATIONAL MATCH BCG
5.56 Y/M LIGHT WEIGHT NATIONAL MATCH BCG
This carrier weighs 10.5 ounces which is .8 ounces less than our standard carrier. Added surface area in the front of the carrier gives a tighter fit when the bolt is in battery for more consistent lock up. The lighter weight results in less reciprocating mass for lower felt recoil. Also good for  hunters who are trying to keep the weight down.  Available in 5.56 and 7.62x39

Balanced Bolt Carrier Group Complete
Description
With a long history of innovation Sharps Rifle Company (SRC) has done it again!After developing the most technologically advanced AR-15/M16/M4 bolt in the world Sharps felt compelled to develop a bolt carrier unit to complement it. We began by identifying what the shortcomings were with the traditional AR-15/M16/M4 bolt carrier. We identified two primary issues. The first being the rotational camming of the carrier during the unlocking portion of the operational cycle. The second being the canting of the bolt carrier group upon firing due to the gas pressure exerted to the gas key which naturally causes the front of the bolt carrier group to rise and the rear of the bolt carrier group to be pressed downward during its rearward travel. Armed with this knowledge our team of innovative engineers set about to correct those shortcomings. We used computer design technology coupled with real world testing to address both of these issues. When the process was completed we sent the resulting prototypes to a broad spectrum of professionals who use their rifles hard for their personal evaluation and feedback. Their observations were then incorporated into the final design resulting in the new SRC Balanced Bolt Carrier (BBC). The Sharps BBC is precisely machined from S7 steel which then undergoes our proprietary heat treatment process. Finally the BBC is finished inside and out with NP3®/NP3® PLUS to minimize the need for lubricants, to aid in smooth operation and to make clean up a breeze. The BBC has the SRC logo machine cut on the side of the carrier which is visible when the ejection port door is open. It fits standard AR-15/M16/M4 rifles chambered in .223/5.56mm, 25-45 Sharps and 300 Blackout calibers. Superior Corrosion Resistance Every Balanced Bolt Carrier Group is coated with NP3®/NP3® PLUS, an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon™, for self-lubricating corrosion resistance. NP3® PLUS offers far more corrosion resistance for marine and other hostile environments. NP3® PLUS gain up to five times as much corrosion resistance over standard NP3® and up to 10X more than regular electroless nickel!

Sale! LANTAC .223/5.56X45MM Enhanced Full Auto Bolt Carrier Group NiB Coated
LANTAC .223/5.56X45MM Enhanced Full Auto Bolt Carrier Group NiB Coated
LANTAC E-BCG, Enhanced Bolt Carrier Group. M16 Full Auto Style for increased mass and lock time. Our new BCG is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 and Magnetically Particle Inspected. The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, advanced UCT EXO process, unlike standard NiB coatings. This offers extreme lubricity with a friction coefficent of .02 and surface hardness of 82-85 Rockwell C. The carriers patent pending design features unique shrouded and forward facing gas ports that have also been re sized so that gas is vented differently to a standard carrier. This results in a system that runs flatter with a smoother energy pulse. In addition the system also runs cooler and cleaner, there is also less pressurization of the upper receiver when running a suppressed barrel. The flared boss at the tail of the carrier enhances the BCG's lock position within the upper and makes it more consistent, resulting in an accuracy improvement. All critical dimensions are hard turned / ground after heat treat and the bore of the carrier and gas key have been hard chrome lined for the best possible wear resistance. All E-BCG's feature the LANTAC CP-R360 patent pending domed cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx). The ultra smooth head reduces wear within the upper receiver. The BCG's 11.7oz weight helps to increase lock time and smoother operation. Gas keys are properly staked at four points and only grade 8 fasteners are used in assembly. The E-BCG's forward porting and unique shape assist in reducing pressurization inside the upper receiver that can be caused by short barrel rifles running suppressors. However, it should be noted that the E-BCG is not a complete solution for this issue and all rifles are different. 'Over Gassed' guns will suffer to a larger extent from this problem.
