CowCow Technology CNC Aluminum Blowback Housing for TM Hi-Capa / 1911 Pistols
(Color: Silver)

"If your novritsch ssp1 blowback housing needs to be replaced go for this model, avoid others. I tried the edge airsoft bbu and the tolerances would not work together. For all KJ spec hicapas buy this one. Good quality overall.

"Noticeably lighter than the OEM KJW BBU. Definitely helped improve the gas efficiency to where I can actually get off an entire magazine without running out of gas. Also replaced the gas routers on my magazines with purple Nineball/Laylax gas routers. Much tighter tolerances than the OEM unit as well.

"Looks to be good quality. Feels like good quality. Must be of good quality. Unfortunately, I couldn't get it to work properly in an EMG/SAI RED Hi-Capa. Hopefully when I build a TM I'll get to try it out.
