We are running low on 16" recon barrels with mid-length gas systems, but we should have new ones in before the month is out. 20" barrels are out of stock, but should have more in a week or two. Plenty of 18" recon and SPR barrels are in stock.
We do have a limited supply of barrels with unthreaded muzzles and 11 degree target crowns. Please email or call to order these.
