    BRT OPTIMUM build

    BLUF- Very smooth, LW shooter.

    Purpose of build- To build a LW rifle from the ground up with smooth function and light weight as a priority.

    Concept of parts chosen- The Black River Tactical Optimum barrel piqued my interest. I chose a handful of other parts that are such as the LMT E-Carrier and SLR adjustable gas block after looking at feedback from other shooters.

    Build list-
    Magpul SL stock-I prefer the negative pitch.
    A5 RE/Green Sprinco spring/ A5H2 buffer-go to setup.
    Magpul K2 grip-preferred Grip. Haven't experimented much beyond the K2.
    Stripped S&W lower-works with PMAGs, available locally.
    Sionics LPK- my preferred LPK.
    Vltor MUR w/FA- more protection for my face in the event of a kaboom. Possibly more accuracy.
    BCM ambi CH- was the go-to at the time I purchased. Currently prefer Radian ambis.
    LMT enhanced carrier/Sionics bolt- interested in if this will run noticeably smoother.
    BRT OPTIMUM 16" barrel- looking to go LW with the barrel. Interested in the gas system and low weight.
    SLR Rifleworks AGB- supposed to be the best AGB
    ALG V3 13" DDC- simple, lightweight, economical, and doesn't feel like gripping a pencil.
    Forward Control Designs 6315 FH- more of what I like about the A2.
    Accu-washer shim set- a simple way to get a MD torqued to 20#
    LMT rear sight- I have ample time with A2 rear sights. Like them for what they are.
    DD front sight- Looks like an A2 front sight.
    VCAS Multicam sling w/ Magpul QD- VCAS is my go to.
    Aimpoint CompC3 2MOA RDS- Been using since '08.

    Overall, exceptionally smooth shooter. I shoot from below zero to 100+ degrees, and have had no reliability issues. Round count is now 2686 rounds.
