Colt's new M.A.R.C. 901 Series aims to take versatility to the next level, giving shooters a platform that simply switches between AR-15 and AR-10.
From barrel length to rail configuration, the AR can be decked out to tackle nearly any challenge. Heck, just that aspect alone is one of the main drivers of the platform's popularity.
Colt, however, aims to take the flexibility concept a step further by evolving one its most versatile firearms into an entire line.
The four new rifles that make M.A.R.C. 901 Series are basically the evolution of the LE901-16S. And like the original model, the new family of firearms can be configured to take on any trial.
Perhaps, the biggest selling point of the M.A.R.C. (Modular AR Carbine) family’s flexibility is its ability to switch between the two most popular AR calibers. The new guns are sold as AR-10, chambered .308 Winchester, but can quickly become an AR-15.
The series is designed to accept any of Colt’s Mil-Spec .223/5.56 upper receiver with a conversion kit. The kit, sold separately, scales down the magwell, buffer and action spring to shoot the lighter round.
The LE901-16S kicked off the concept of switching between AR-10 and 15, and remains an option in the M.A.R.C. 901 Series. But the four new rifles that have been added to the family aim to take the platform’s flexibility a step further.
The new models – LE901-16SE, LE901 FDE-16SE, LE901-18SE and AR901-16S – achieve much of their adaptability through their rail systems.
Each SE model has a fixed rail at the 12 o’clock position on the receiver and provision to mount rails at the 3,6 and 9 o’clock positions. The AR901-16S features a flat-top upper receiver and a tubular forend, with provisions to mount rails on 16 different planes.
All of the carbines, except the LE901-18SE, are outfitted with 16.1-inch free-floating barrels. Like its numerical designation suggests, the 18SE is designed for those who prefer a longer 18-inch free-floating barrel.
All models in the M.A.R.C. 901 family boast chrome-lined barrels, for longer life and less fouling. And they have a 1:12-inch twist rate (right hand), which will stabilize bullets up to 168 grains.
The SE models of the M.A.R.C. all have VLTOR adjustable buttstocks, while the AR901-16S has a B5 Bravo Buttstock. In both cases, the firearms with 16-inch barrels can be adjusted from 34.24 inches to 37.5 inches in overall length.
All but the FDE-16SE come with flat black finishes. The FDE model, on the other hand, has a flat dark earth finish on its upper and lower receivers along with matching furniture.
The SE models of the direct-impingement rifles each come outfitted with flip-up adjustable sights. The AR901-16S does not come with a sighting system included.
The MSRP on the M.A.R.C. 901 Series is as follows: LE901-16SE and LE901-18SE $2,181, LE901 FDE-16SE $2,281 and AR901-16S $1,623.
