SIG Sauer is coming out with two new complete, drop-in AR-15 upper-receiver assemblies. These complete kits include everything you need to upgrade your AR lower.
MCX-SPEAR LT 9-inch Upper AR Conversion Kit 300BLK – FDE
The MCX-SPEAR LT developed for the Special Forces community and allows you to convert any AR15 lower into either an SBR with a stock and the appropriate paperwork or a large-format pistol with a brace.
Features:
- Adapts with any M4/AR15-spec lower assembly
- Dual-rod recoil assembly eliminates buffer system
- M4 adapter allows for picatinny rail folding stock capabilities
- Adjustable gas system for suppressor optimization
- Quick-change barrel design allows to easily swap calibers and barrel lengths
- Gas-piston design reduces exposure to carbon fouling
- Designed to go 20,000 rounds before any maintenance-part replacements
- Ambidextrous charging handle with gas deflector
- Replaceable parts (cam path follower, feed ramp, forward assist/deflector, charging handle locking pins) allow for longer receiver life over standard AR designs.
- Tapered bolt design functions more reliably and lasts longer than standard square-lug M4 bolt designs.
- Nitride coated, cold hammer forged barrel for more accuracy and barrel life
SIG AR Upgrade Kit
Upgrade your AR rifle or lower assembly with a complete, drop-in M400 upper assembly. This kit includes all the necessary components for a complete swap, including a two-stage match trigger as well as the popular Tango-MSR LPVO 1-6X24mm second focal plane (SFP) riflescope. The free-floating handguard uses a new steel lockup design that significantly reduces handguard deflection by providing maximum rigidity and allows for accessories to be attached on all four sides with no effect on accuracy. The 2-Stage Matchlite Duo trigger provides a crisp 4.5-6.5-pound pull weight with a flat blade design for a precision feel.
