-Our LLW3 Upper Assemblies are extremely reliable and like to run on 105-147 grain round nose ammunition.  We maintain a very precise chamber and headspace dimension, to SAAMI spec for 9 x 19 (9mm Luger), giving the competitor exceptional accuracy with unmatched reliability.


Wiland USA LLW3 Upper Assemblies hold National Steel Challenge speed records and have won numerous matches already in the last few years.


Note: Do NOT use this assembly with factory ammunition.

It is specifically designed to cycle low-power ammunition for steel match shooting.  Although the bolt & barrel can more than handle factory loads without a problem, the buffer and buffer spring are set up for light, special steel match loads.

If you would like to use factory ammunition with this assembly, you will need to switch out the buffer and spring to a 9mm heavy buffer and appropriate spring.

Damage to your firearm and injury may occur due to using factory ammunition with the configuration of this assembly as it arrives to you.

Please contact us via email or phone to discuss if you wish to use factory ammo in this assembly.

    9mm upper

    Posted by John R Dorn on May 2nd 2021

    I've only gotten to shoot it a few times and I'm still finding a load it's happy with, with the powders I have. I shot it in its first match and it ran fine, then click, no bang. One of the trigger pins fell out. Certainly not the uppers fault. Anti-rotate pins have taken care of that. Will be shooting it this weekend with a variety of loads and a chrono. Once dialed in this will be a 5 star upper!
