Converted over a JG M-4 S System into a metal body. The JG full metal body for M6/M16 has worked out great. I dropped in a JG M130 gear box, Dboy full metal hop up chamber, Matrix 6.03mm 303mm tight bore inner barrel into a Madbull one piece metal outter barrel with no problems.
1).All internal upgrade parts fit perfectly.
2).All internal upgrades now have a improved 'protective shell' to prevent damage.
3).The metal body has improved the over all look of the AEG with a more combat realistic presentation.
4).Price is unbeatable at $65.00 compared to other metal body parts from other companies.
5) Other upgrades that fit well onto the JG metal body were a Magpul grip handle.
6) G&P Delta ring fit on with on with no difficulties.
1).AEG is a little heavier.
2).I find that metal magazines fit perfect and the Star Magpul plastic magazines donot fit very well. This was not the case prior to swapping the original plastic body for the metal. Both magazine types fit equally well in the plastic body. Go figure.
3) Magazine release is a little funky. The release does not seem to go very flush into the body. Magazine is tight when in the AEG.. However I may replace the mag release and look for another type that will retain a flush. This might become a problem in the field if the mag release gets snagged on brush or tree branch.
