We take special care in bringing you the best in short barrels, and use the best artisans, both in-house, and in our extended supply chain, when something has to be engineered to a Colt production barrel. Our collectors and cloners will want the 10.3" barrel for historical accuracy. The Daniel Defense is a great option, as it is now being used by US Special Forces in limited numbers, and is readily available and affordable. For more authenticity, choose a Colt 10.3" barrel.
Shooters and law enforcement typically choose the 11.5" barrel, as it has better overall performance, especially in the heavy (SOCOM) profile. Our LE customers tell us that they will only use Colt barrels in 10.3" to 14.5" lengths. Colt truly does dominate that market, while other barrel companies own the long-range and sniper market.
As always, we are here to help. Drop us a line, or use our online CHAT to ask about our short barrels.
