Reptilia's patented turn buckle technology takes a different route: the barrel nut goes on to a 50 ft-lb torque spec, then the turnbuckle is brought up hand tight with red thread locker and draws the handguard into alignment against it.\u003c\/p\u003e\u003cp\u003eThe tube itself is a 6061-T6 aluminium extrusion with a 33.5 mm internal diameter, finished in MIL-STD Type III, Class 2 hard anodise, and M-LOK slotted for accessories. Three lengths are offered here — 10.5 in at 255 g, 13 in at 309 g and 15 in at 358 g — each in Black Anodized or FDE Anodized.\u003c\/p\u003e\u003ch3\u003eWhy shooters choose the Reptilia Handguard\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatented turnbuckle clamping\u003c\/strong\u003e — draws the handguard square to the receiver rather than pinching it there\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree-float tube\u003c\/strong\u003e — nothing touches the barrel, so nothing loads it off zero\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6061-T6 extrusion, 33.5 mm bore\u003c\/strong\u003e — clears a wide range of barrel and gas system profiles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM-LOK slotting\u003c\/strong\u003e — direct mounting for lights, lasers, grips and sling points\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree lengths\u003c\/strong\u003e — 10.5 in (255 g), 13 in (309 g) and 15 in (358 g)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat the Reptilia Handguard fits\u003c\/h3\u003e\u003cp\u003eFits all M4 upper receivers, on AR-15 and M4 rifles.
