Olympic Arms 10mm flat-top 11.5″ complete upper assembly SOLD

Olympic Arms 11.5″ SS barrel 10mm flattop complete upper assembly.

A very handy pistol upper or SBR upper in the powerful 10mm caliber.   The upper is in the rare length of 11.5” with a SS bbl and utilizes a blow back operation.  This complete upper features a flat top upper receiver with internal ejector, charging handle, 10mm bolt assembly, 11.5″ SS barrel, delta ring, carbine style handguards and handguard cap, FSB (front sight base) with A1 post and bayonet lug, threaded barrel with Stoner style flash hider.

This is a used personal upper and has been fired approx 350rds.  It comes with a converted .41AE Uzi mag with the block welded onto the back, which I believe is a 20rd mag.  Olympic now uses a different magazine that is less expensive since the Uzi mags are preban mags.

Barrel is marked SS 10mm.

The use of the new style Olympic Arms mags may require a notched feed ramp according to the Olympic Arms website – this upper has the notched feed ramp.

This item is now sold.

NOTE:  4 extra Uzi .41AE mags are possibly available. They have been modified to work with a standard 9mm magwell block and milled for the AR-15 mag catch.  They do not have the block welded on back like the above mag.  They could be modified to work for 10mm or could be used in .40S&W  or .41AE AR-15 conversion.  Please call to discuss options.
