YOU WILL NEED TO PURCHASE THE 300RD M4/M16 HI-CAP MAG SEPARATELY. THIS ITEM INCLUDES THE ADAPTER UNIT ONLY.
Our take: This is a revolutionary new product from JG, made to resolve the issue of low magazine capacity on your standard, run of the mill stock P90/E90 airsoft AEG rifles. This brand new box magazine adapter from JG allows you to take the guess work out of CQB play with your P90 ... gone are the days when you had to take a guess-timate at how many rounds were left in your 70rd P90 mag.
This box magazine adapter is surprisingly sleek, and keeps out of your way to make your P90 a compact and highly versatile airsoft AEG, with the exception being you have over 1600 ROUNDS at your disposal!
Installation couldn't be simpler. Just insert the entire magazine down into your mag well, just like a normal P90 magazine, load the BBs from the hopper (which will feed into your 300rd M4/M16 hi-cap magazine's BB reservoir), wind the hi-cap gear, then shoot! This magazine adapter requires a M4/M16 hi-cap mag to work.
PLEASE NOTE: You must open the top hatch on the M4/M16 magazine PRIOR to loading it into your box mag in order for the BBs to fall from the hopper into your M4/M16 magazine's BB reservoir.
Compatible with Echo 1, JG, KS, AGM, Tokyo Marui and CA P90 full metal gearbox AEGs. Good quality, fit and finish.
