Explain your AR15 layout...

[TheRifleman]

Zeroed to 55 grain Speer Gold Dot .223 using the 50/200 yard zero.

-LMT SOPMOD, gives me the best balance, best cheek weld, and even when collapsed it's still in a pinch ready to go LOP for close quarter emergencies.
-V7 castle nut, to shed some weight as every little bit matters.
-Radian endplate, for weight reduction.
-Magpul buffer tube, it's as if the SOPMOD and that tube were made for each other. Super smooth but not noisy at all.
-Magpul K2, it allows me to get closer to the gun with a shorter LOP than the traditional A1 and A2 grips, and allows for a more comfortable and less fatiguing thumb over bore grip.
-FCD trigger guard, not a sharp as milspec OEM.
-FCD ASF-90 short and long offset levers. As a southpaw it's so much more efficient to thumb to fire and trigger finger flick back to safe on and off. This becomes apparent after even just one whole day on the line at a course. The levers are kept in place by roll pins, not screws or spring loaded detents.
-Odinworks extended mag button, much more efficient to thumb it with the non firing support hand leading to faster more positive magazine changes.
-CMMG pivot and takedown pins, easier to use a punch should an out of TDP spec upper be placed on top.
-FCD ABC rear biased and serrated as it should be, I have tried a lot of bolt releases and again saying this as a southopaw, is one super rugged yet super fast to either rest the bolt or to put back into action with.
-Geisselle SSA, one of the best IMO 2 stage triggers and definitely good for duty use. Not too light, 1st stage allows for self correction if a bad pull is to be initiated or not before that stiffer wall on the 2nd starts.
-JP Enterprises Silent Captured Spring, smooths the cycling for an improved shot recovery.
-FCD 9 pound mag release spring, I've had mags drop unintentionally while slung, that stopped after the heavier weight spring was introduced.
-Colt mag release, TDP spec snag and problem free.
-V7 lightweight FA, dropping weight wherever it can be done.
-Radian Raptor-SL, I love the Raptor but the SL is less pronounced and less prone to snagging if there was such a thing with ambidextrous CH's. And Ambidextrous because I'm a southpaw and it's faster, YMMV.
-Microbest phosphate BCG, TDP spec.
-V7 ejection port door, because weight savings where I can without impacting critical areas.
-DSA Dogbone M4 upper, TDP spec that many SOPMOD M4's were rebuilt with.
-Magpul MBUS Pro and MBUS Pro LR, durable, holds zero even when banged or dropped.
-SOLGW M76 Wedgelock, super strong anti torque mounting system and a perfectly shaped circumference to thumb over bore with even with heat shield panels.
-Ballistic Advantage Hanson 13.9, wanted a lightweight barrel that was both durable and in a length that I could P&W to a legal 16 to get as short as possible without doing another Form 1.
-Reptilia QD sling swivel, durable yet doesn't use up more than one Mlok slot. Brings the sling a tiny bit further out so there's less of a chance of brass bouncing back in the port causing a malfunction.
-Magpul MVG, this is used as a hand stop when thumb over bore and is the perfect stabling solution for barricades, stumps, boulders, trees, structure sides, etc. Hand stop that I can have my thumb rested on and pull against while or rest against the support hand wrist.
-Magpul Type 2 heat shield panels, a very grippy texture that I have never lost gripping with or have been burned.
-Railscales heat shield, I had a fitment issue underneath because of the proximity to the gas block with the M76 FF with the Type 2's and the Railscale shield solved that and without being a fatty.
-Cloud Defensive Rein 2.0 short tube, I've owned Rein 1.0, seen the Owl in use, have Surefire 300's and a 600, and Modlite OKW & PLHv2. The 2.0 is a cooler light, has a pressure pad that I am a fan of, and has a thumb activate pressure pad. And it's very durable that gives great throw and lots of spill.
-Magpul offset mount, strong, lightweight, and durable mount for scout lights. I prefer offset mounted lights because I want a reduced area as much as possible to reduce it's silhouette.
-FCD 6315 KM-L, I wanted a great MD in the correct length to P&W and be awesome at flash suppression with a Keymo mount to mount a Dead Air Sandman to at some point.
-Scalarworks LEAP/01 1.57 that I may or maybe not change to a 1.93, durable yet lightweight micro mount.
-Aimpoint M5, both the T-2 and H-2 that I own have very stiff brightness knobs that I have to use a zen or look at to make sure it's where I want it to be. With the M5, I can visually see it and know instantly where to place it with it's white dot on the knob, and without being distracted like I would with the 2's.

This is my lessons learned from a 40 hour Carbine 223 course at Gunsite, rifle. Lightweight within reason, a simple dot with a BUIS set to back it up in case of force on force washout or a dead sight. I like my SBR a lot and it's what I ran at Gunsite that I know it works and works all the dang time. The 11.5 while a great short barrel length, I wanted to get as much velocity as I could with the shortest yet non NFA equipped rifle that I could bring across most state lines without doing asking for permission to take my SBR with me. In fact if I ever do another SBR it's going to be in 12.5 because my mind was blown at just how close in velocity a 12.5 is next to a 14.5.
