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
BCM BCG
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.
