CUSTOM ONE-OF-ONE 300 BLACKOUT AR-15 — SPARE NO EXPENSE BUILD

Description

This is not a factory rifle. This is a hand-built, one-of-one 300 Blackout AR-15 assembled from top-shelf components — no corners cut, no budget compromises. Every part was selected for performance, reliability, and quality.
BUILD SHEET:
Radian Model 1 Billet Upper/Lower Set w/ 8.5″ MLOK Handguard — precision-machined billet aluminum, not forged. Radian is the gold standard in fit and finish.
10.5″ 300 Blackout Barrel — Black Nitride finish for corrosion resistance and longevity
Radian Raptor SD Vented Charging Handle — ambidextrous, vented for suppressor use, buttery smooth
JP Enterprises Silent Captured Spring — eliminates buffer spring twang, smoother recoil impulse
Hipertouch Competition Trigger — crisp, clean break with a lightning-fast reset
300 Blackout Nitride Bolt Carrier Group — properly headspaced and ready to run
Dead Air KeyMo Compensator (1/2×28, Long Version) — quick-detach suppressor ready out of the box

Magpul MOE SL-S Carbine Stock (FDE) — slim, lockable, QD sling points
Holosun HS403C Red Dot + HM3X 3X Magnifier Combo — flip-to-side magnifier, shake-awake dot, ready for CQB or reaching out
Over $2,700 in parts alone.
PACKAGE INCLUDES:
Complete custom rifle as described above
I have over 1000 rounds of ammunition if you would like to discuss.
10x 10-round magazines
Everything you need to leave the shop and hit the range — or be ready for whatever else.
This build is suppressor-optimized with the Dead Air KeyMo mount and vented Raptor SD charging handle. Slap a can on it and you’ve got one of the quietest, smoothest-shooting 300 BLK platforms money can buy.
