    Nemo Arms Recoil Reduction BCG

    Rainier Arms Pre Order Exclusive.

    https://www.rainierarms.com/nemo-arm...nd-buffer-kit/

    Nemo’s patented bolt carrier and buffer system has never been offered in a builder’s kit until now. The same quality components, high-end coatings, and innovative recoil reduction technology that are used in NEMO’s OMEN and XO model lineup are now available in a kit for your large frame AR. Use this kit whether you are building a rifle from the ground up or looking to reduce recoil in your existing rig. The technology in the bolt carrier group reduces bolt speeds and felt recoil when the recoiling mass bottoms out in the buffer tube. Other products are designed to minutely dampen the force at the moment the recoiling mass bottoms out, whereas NEMO’s design creates a dynamic solution at the beginning of recoil that creates a low “bottom-out” force. This is accomplished by forcing the buffer to bottom out and start its return before the BCG has finished its recoil cycle. The buffer and BCG momentum are opposite, and the result is a noticeable low impact “bottom-out” force.


    Kit includes:

    NEMO’s complete Bolt Carrier Group stacked with premium features:

    Recoil Reduction Carrier Plunger System, High Pressure Bolt and Ti Firing Pin with return spring, Tool Steel Ejector and Extractor with high strength springs, One-Piece Gas Ring, POF’s patented Roller Cam Pin, Nickel Boron Diamond-Like Carbon and Chrome coatings, Staked Carrier Key

    NEMO’s proprietary Buffer with hardened, Nickel Boron coated impact face

    NEMO’s Buffer Tube with indexing tabs (MIL-SPEC Diameter)

    NEMO’s Custom Buffer Retainer and spring

    NEMO’s Custom tuned Buffer Spring

    NOTE: Castle Nut & Receiver Plate NOT included.


    Kit Compatible with most AR-308 Large Frame Receivers, Direct Impingement only

    Including:

    DPMS Pattern Receivers (LR-308™)

    ARMALITE Pattern Receivers (AR-10™)

    NOT Compatible:

    DPMS Gen II Receivers

    POF Revolution


    BOLT/BARREL HEADSPACE MUST BE CHECKED WITH PROPER GAUGES BEFORE FIRING

    NEVER REMOVE FIRING PIN SPRING FROM THE FIRING PIN

    Recommended Gas Port Diameter Sizes

    16” 308 Win Barrel: Mid Length gas tube = .070

    20” 308 Win Barrel: Rifle Length gas tube = .086

    16” 6.5 Creedmoor Barrel: Mid Length gas tube = .072

    18” 6.5 Creedmoor Barrel: Mid Length gas tube = .067

    18” 6.5 Creedmoor Barrel: Rifle Length gas tube = .093

    20” 6.5 Creedmoor Barrel: +2 Length gas tube = .098

    22” 6.5 Creedmoor Barrel: +2 Length gas tube = .096


    NOTE: These sizes are approximate and can vary depending on the multitude of variations seen between manufacturer’s dimensions. It is recommended that the kit is installed and tested initially without modifying gas port sizes, gas blocks, or gas tubes. Initial testing should include confirmation of cycling and last round lock-back of the BCG. Adjusting gas port size or adding an adjustable gas block may be required for optimum performance.
