Description
For years, buying a Colt meant getting a rock solid carbine and then spending your own money swapping out the basic furniture. The EPR II Pro flips that script. Colt started with the same TDP components and MIL-SPEC materials, coatings, and processes that earned the 6933 its reputation, then finished the rifle the way working professionals set them up anyway. The 11.5 inch chrome lined barrel keeps this short barrel rifle quick handling in vehicles, hallways, and anywhere a full length carbine feels like too much gun.
What Makes the EPR II Pro Different
The centerpiece is Colt's new free float handguard with M-LOK slots in seven orientations, a full length Picatinny top rail, anti-rotation tabs, and two integrated steel QD sockets. It's rigid, light, and gives you consistent mounting real estate for lights, lasers, and hand stops. The Pro trim adds the upgrades that matter: an ambidextrous safety selector and magazine catch, a Radian Raptor ambi charging handle, a QD receiver end plate, and an enhanced trigger guard. Furniture is all Magpul, with a MOE SL stock, MOE K2 grip, and MBUS Pro flip up steel sights that hold zero and stay out of the way of your optic.
Suppressor Ready with the SureFire SF3
This particular configuration, the LE6933-EPRII-PRO-SF3, comes from the factory wearing a SureFire SF3 flash hider on the 1/2×28 threaded muzzle. That means it doubles as a fast attach mount for SureFire SOCOM series suppressors, so if you run SureFire cans you can go from bare muzzle to suppressed in seconds with no extra hardware to buy. Even unsuppressed, the SF3 does a fine job taming flash from the short barrel.
A Colt SBR That's Ready to Work
Between the pony on the receiver, the duty grade build quality, and a parts list that reads like a serious end user's wish list, this is one of the most complete factory SBRs Colt has ever offered. It ships with one 30 round magazine and pairs naturally with a red dot or LPVO up top.

Frequently Asked Questions
What does the SF3 in the Colt EPR II Pro SF3 mean?
It refers to the SureFire SF3 flash hider that comes installed from the factory. Beyond cutting muzzle flash, the SF3 serves as a fast-attach mount for SureFire SOCOM series suppressors. If you already run a SureFire can, this rifle is ready for it the day you take it home.
How is the EPR II Pro different from the standard EPR II?
Both share Colt's TDP-built receivers, chrome lined barrel, and the new free float M-LOK rail. The Pro adds an ambidextrous magazine catch, a Radian Raptor ambi charging handle, a QD receiver end plate, the Magpul MOE K2 grip, and MBUS Pro folding sights. It's basically the fully loaded version, so there's less to upgrade later.
Is the Colt EPR II Pro accurate with an 11.5 inch barrel?
Yes. The EPR II Pro line has printed groups in the neighborhood of an inch at 100 yards in published testing with quality ammo, which is excellent for a duty grade carbine with a mil-spec trigger. The free float handguard helps a lot here since nothing hangs off the barrel to disturb harmonics.
Can I mount an optic and still use the MBUS Pro sights?
Absolutely. The full-length Picatinny top rail gives you plenty of room for a red dot or LPVO, and the Magpul MBUS Pro sights fold flat when not in use. Most people run them as backups that co-witness or lower one-third with a red dot.
