SBR & Carbine Length M4

Operator:
Brendon "BEARD Actual" Wright

Details:
So as most of you that airsoft with me know, I spend the vast majority of my playtime at indoor CQC fields, as opposed to outdoor fields. As amazing as the Masada is, with its 14" barrel and fixed stock, it can become a bit unwieldy in a large percentage of encounters. I love using Tilly, but she is still just a handgun and not ideal for any prolonged skirmishes. Once again, I found myself in the same situation as I did with Lana, requiring a purpose-built weapon built to my exact specifications.

Still need to install bolt forward assist for aesthetics, and new selector plate for more smooth firing mode transition. Video taken: First one demonstrating raw fire rate.
