Title: Javelin CO2 to HPA Umarex conversion kit
Post by: tkerrigan on February 16, 2022, 08:08:52 PM

Has anybody heard what FPE - FPS this conversion kit will add to the original 300FPS CO2 version if any?  Does it equal the stats of the new HPA 375FPS Javelin?  Inquiring minds would like to know. At $60 plus freight it would be a real bargain if it does the job.    Regards, Tom

i doubt it brings it up to full speed , the javelin valve is cast pot metal , so i cant see handling much higher pressure than about 1400 psi.
