Lilja 10.5" / 12.5" / 16" Barrels (option for complete upper, round 2)

I would be interested in a 20" barrel.

You’d be better off contacting rebby at Six Sigma Arms if you’re interested in a Lilja barrel. To my knowledge rebby isn’t doing group buys but keeping barrels in inventory at his business Six Sigma Arms. Here is a link and there is a phone number if you choose to call.

It's crucial to maintain the appropriate gas system length when shortening a barrel. Generally, for an 8.5" or 9" barrel, a pistol-length gas system is more suitable to ensure proper cycling and reliability. Always consult with a qualified gunsmith for personalized advice based on your specific firearm.
