This is a unique and great addition to anyone's military style collection.  And, what a name.  FN !.  This is roll-stamped on the port side, so the real deal.

Military replica, made to the same specifications as the military-issue M4A1, however without the select fire feature.


  • Semi-automatic, only
  • Ambidextrous selector
  • Anodized, flat-top receiver with MIL-STD 1913 rail (12 o'clock) and UID label
  • Collapsible, 6-position with sling mount

The FN 15 rifle series is based on FN's semi-automatic, direct impingement platform for the 5.56x45mm, .223 Remington, and .300 AAC Blackout (7.62x35mm) cartridges, and offers something for everyone, whether the application is tactical, collector, or target/competition.

THIS IS A SERIALIZED FIREARM.  IT MUST SHIP TO AN Federal Firearms License holder.  No civilian exceptions.

When you check-out:  We no longer take PayPal, as it has caused some confusion on the purchase of firearms, which is contrary to PayPal policies, and we had no way to restrict it  just for FFL items.  

A firearm cannot be sent directly to you.  I am sure you know this, but for the fake-news reading this, who might think that a firearm can be mailed to a buyer, I have to reiterate:  A firearm or federal regulated serialized item (like a receiver or suppressor), only a federally licensed firearms dealer may receive such an item. It would be good to know your FFL and their shipping address before purchasing.  If you know the FFL address, please put this in your shipping address at check-out.  

Note:  California residents, click here for CA compliant processing.  This will also work for New York residents.  We will act on your behalf and instructions to ship to restrictive states, but ultimately, it is your responsibility to know the local and state laws.  We are in Virginia, and cannot, and do not know all the nuances of other states.  If we ship to your FFL, and there is an issue, we cannot accept a return, so please make sure that you know and follow your local and state laws.

Please note our shipping timelines.  We do not ship immediately.  Also, if you choose the free 5-7 day shipping, those orders ship after all other forms of shipping chosen.  Express shipping is given priority. 

Be sure to read our return policy.  While your satisfaction is our primary concern, we are limited in a highly regulated business environment by what we can and cannot do, and the number of local, state and federal regulations.  We do not accept returns for ammunition and firearms, other than obvious defects.  Your gun dealer or transfer agent is responsible for inspection for defects:
