If you’re after a high-performance primary with a militant aesthetic, check out the Specna Arms SA-P04 PRIME™ M4A1 CQBR AEG! Equipped with some of the best internals we’ve ever seen in an out-of-the-box AEG, the SA-P04 boasts a powerful Dark Matter brushless motor, CNC 16:1 ratio steel gears running on 8mm J-CAGE bushings, a reinforced tappet plate, and much, much more! The Prime™ is Specna’s newest line of AEGs, taking its traditional AEG silhouettes and stripping away the internals to make room for a new set of improved parts to increase performance, consistency, and rate of fire. The highlight of this AEG is the option to choose either the Gate ASTER II Bluetooth™ MOSFET or the HAL™ MOSFET, substantially improving trigger response and programmable firing modes. Which you choose depends on your needs; the ASTER II is ideal for the skirmisher seeking a plethora of advanced functions, and the HAL™ version is great for users who prefer an easier-to-use yet still advanced MOSFET. If you’re into the classic M4A1 look and want the best internals an out-of-the-box AEG can hope for, Specna Arms has your six with the SA-P04 PRIME™ M4A1 CQBR AEG. A beast in terms of both build quality and performance, the SA-P04 is the ideal base for any military-style custom build!
