We have seen a good number of reviews of the Double Eagle M917G UTR45 AEG but this review by Anvil Airsoft TV (AATV) is one of the most definitive. This is a compact AEG that has an adjustable cheek rest as well as programmable firing modes with the Falcon electric cnrol system allowing one to set the mode up to 5 round bursts as well as as trigger sensitivity and protection for the battery and motor. We recommend you watch the review made for Taiwan Gun.
