Sons of Liberty Gun Works M4 L89 5.56 NATO 11.5" 30rd SBA5 Brace Pistol

The SOLGW M4 L89 pistol is the 11.5" 5.56mm member of the L89 series, the line of M4s Sons of Liberty Gun Works builds for the professional end user. The upper and lower are machined from aluminum forgings and finished in black. The 10.75" L89 Drivelock handguard locks to the upper with anti rotation tabs and a stainless steel pin, and it has 7 sided M-LOK slots and integral steel QD cups at 10 and 2 o'clock on both sides. An extended steel barrel nut gives the handguard a more rigid lockup.

The 11.5" Liberty Fighting Barrel is a medium contour steel barrel with a .223 Wylde chamber that accepts both .223 Rem and 5.56 NATO, a chrome lined chamber and bore, a phosphate coated exterior, a carbine length gas system and an A2 flash hider on 1/2x28 threads. The bolt carrier group is chrome lined, high pressure tested and magnetic particle inspected, in a full auto profile. Recoil runs through SOLGW's A5 length buffer system with a 9 position receiver extension and an A5H2 buffer, set up for reliable running with a suppressor. Controls are the ambidextrous Liberty charging handle, the Liberty two stage trigger and an ambidextrous safety selector, and the brace is an SB Tactical SBA5. One 30 round Gen3 PMAG is included (a compliant magazine where required), and each pistol is individually built and test fired.
