Q: Can I build my upper while attached to the lower receiver?
A: NO! When assembling your upper receiver DO NOT torque the barrel nut or muzzle brake while the upper is attached to the LW-4 (or any other model) lower receiver. Assembling the upper improperly could cause damage to the lower receiver and will NOT be covered under the factory warranty. When assembling an upper you should use a reaction rod or a vise block specific for assembling upper receivers.
