Hey guys new to the forum. Always been a gun guy but somewhat new to the AR platform. I recently picked up a used LaRue LT15 with a 18” Stealth barrel. I swapped it to a 16” stealth and running a SureFire Recon 2 Mini Suppressor. Love the gun extremely accurate but it’s a tank. Thinking of buying and extra upper and adding a lightweight barrel just as an extra set up. What barrel would you recommend for a suppressed 16” to bring the weight down for more of a close range setup?
