Vertexops - free shipping w/purchase over $50... confirmed...
Supposedly free V-7 lightweight bolt catch w/purchase over 150... Hasn't worked - waiting for midnight their time...
10% off w/purchase over 250 (haventvtried yet - could be after midnight)...
For those unaware - this site is good source for lightweight builds... V-7 makes a lot of lightweight parts - and this site has best prices (that I know of).... Tactical Link. Com also has a lot of quality parts - but never on sale... V-7 has their own site but Vertex Ops has better pricing.
FWIW, I bought a MI lightweight M-LOK handguard from them on last build - they were the only ones that had it other than manufacturer... It's the lightest handguard I know of besides KMR (which I also have)...
K - no more type... Gonna see if it can get the lightweight bolt release
