Spikes Tactical Barrel st-16" m4 le-556
by Ronald Fortney
This barrel came very fast considering the times we live in now. Very happy. Just what I needed to finish my build.
top quality Spike's
used two spike's barrels for my last two builds. easy to install with YHM gas blocks and YHM flash hiders. functioned great, but haven't had a chance to truly check their accuracy.

Spikes Tactical Barrel ST-16" M4 Carbine LE-5.56
Barrel mounted on Aeropresion stripped upper with no problems. I shot 100 brass rounds through it this past weekend at the range with no problems. I would purchase again.
