The SLR-B30 foundation is a large-frame AR receiver set machined from billet aluminum, with an integral trigger guard and a flared magwell for efficient magazine changes. The lower is marked "MOD. SLR-B30" and "CAL: MULTI," with the maker’s mark "SLR RIFLEWORKS, WINTER GARDEN, FL." Per SLR guidance, the platform uses DPMS/SR-25 pattern barrel-nut thread compatibility. This rifle is a semi-automatic, direct-impingement .308 Win with a 20+1 capacity.
The 16 inch barrel is paired with an SLR free-float M-LOK handguard featuring a full-length 1913 top rail, offering stable accessory mounting and clear sight alignment. The permanently attached (pinned and welded) muzzle device is a SureFire compensator. A SureFire Warden blast regulator is installed over the compensator via the quick-attach collar and is removable. The barrel is threaded, with the compensator secured per the pinned-and-welded installation noted.
Controls and ergonomics are upgraded throughout: a Timney trigger for a refined fire control, a Radian 45/90 ambidextrous safety selector, a Battle Arms Development extended magazine release, and an SLR ambidextrous charging handle. The Magpul UBR adjustable stock provides a solid, adjustable interface, with a 13.5 inch length of pull. The rifle is completed with a polymer pistol grip.
Optics are fully set up with a Trijicon Credo HX 1-8x28 FFP scope featuring a red/green segmented-circle reticle and a 34 mm main tube, mounted in a one-piece 34 mm mount. The scope is accompanied by its factory box, manual, lens cloth, and a neoprene cover. One 20-round SR-25/DPMS-pattern metal magazine is included. Note: a discrepancy was observed between user-supplied and photographed serial characters (second character appears as the letter O vs numeral 0).
