William, who works at Arisaka Defense, sent us a photo of his new AR-15 build. He wrote …

This is a custom build that I assembled from scratch, consisting of:

BCM Upper Receiver
BCM 14.5″ ELW barrel
Geissele SMR MK8 M-Lok handguard
Magpul MBUS Pro sights
Trijicon ACOG TA33
Arisaka 600 series light body with Surefire KE2-A head and Z68 tail cap
Arisaka M-Lok inline scout mount
Arisaka M-Lok finger stop
Silencerco Saker

Noveske Gen 2 lower receiver
Vltor A5 receiver extension
Geissele G2S trigger
Magpul MIAD grip
Magpul STR stock

I use it primarily for product testing, carbine classes, and ringing steel out to 400 yards.

Thanks William.

    Nice. Looks good.

    Have the same lower (chainsaw) sitting in my safe, they’re excellent but I just have nothing to do with it just yet.

    Rifle looks great
