Details

This Foxtrot Mike AR-15 pistol caliber carbine complete upper receiver comes with a huge assortment of features and improvements that can’t be had if you build yours from the ground up. With the FM products .45 ACP AR upper receiver, you get the functionality of a non-reciprocating side charging handle instead of the traditional T-handle. Now you can charge the rifle while still on target without having to lower it from your shoulder. The upper receiver and handguard are a near-monolithic design with a proprietary lock system that ensures the rail won’t loosen over time. The slim free float handguard features the popular M-LOK system, so you can attach lights, rail sections, or other accessories. Underneath the 8.75” M-LOK handguard is a 7” 4150 chromoly barrel that has a 1:16 twist rate for stabilizing the .45 ACP projectile. This barrel comes with a FM products blast diffuser to help tame the concussion of .45 ACP. Why build a .45 ACP AR-15 from the ground up when you can get a head start with this complete upper from Fox Trot Mike Products.

  • Non-reciprocating fixed forward charging handle

Manufacturers Note: FM Products does not support the following items, using these may void the lifetime warranty associated with our uppers;
 
1) FM Products does not support Aluminum Cased ammo.  Blow backs have a much higher pressure spike in the chamber than a handgun.  Using Aluminum cased ammo in a blow back PCC is dangerous and will void the lifetime warranty of an FM Products Upper Receiver.
 
2) FM Products does not support import magazines besides OEM Glock magazines.  We recommend Magpul, OEM Glock and ETS magazines only.
 
3) FM Products does not support Spikes Glock style lower receivers.  The LRBHO requires consumers to modify the FM Products upper, to make egress for the Spikes LRBHO.  The FM Products upper is cut to the Colt spec, therefore we have no plans to deviate from that.  Modifying your FM Products Upper to accommodate a Spikes Tactical Glock style lower will void the lifetime warranty on our PCC Uppers.   
 
4) We only recommend Sylvan magwell adapters, as they require no modifications or adjustments to work properly.   FM Products does not support Stern Magwell Adapters as they require regular adjustments to work properly.
