HELIGUN EX-17<br />
l2H Weapon is recoil and gas 12M<br />
operated. Insensitive to<br />
different aircraft mounts<br />
l3H <strong>Heligun</strong> is extremely sim- 13M<br />
ple. Has only 69 gun parts<br />
and 14 moving parts, resulting<br />
in lower unit cost<br />
l4H Simple maintenance. Quick- 14M<br />
disconnect disassembly.<br />
Field strips in 20 seconds<br />
into 14 parts, each large enough<br />
to handle with gloves. No<br />
tools required for field<br />
stripping<br />
15H Uses two barrels. Barrel life 15M<br />
estimated at 15, 000 rounds per<br />
set. Use of rifled revolver and<br />
smooth bore barrels, as in 20mm<br />
Mk 11 gun, may increase barrel<br />
life a corresponding fivefold<br />
16H Design features and simplicity<br />
are well proven in 20mm<br />
Mk 11 gun<br />
17H Accuracy and dispersion<br />
optimum for air-to-ground<br />
targets<br />
18H Weapon has recoil travel<br />
built in, so soft mount is<br />
not required. Receiver is<br />
fixed, simplifying feed<br />

MINIGUN XM 134<br />
HTC-AD 66-29<br />
Motor-driven weapon performance<br />
is independent<br />
of aircraft mount rigidity<br />
Minigun cost is higher,<br />
because of number and complexity<br />
of parts<br />
Possibly lower maintenance<br />
frequency and greater service<br />
life, since the weapon is<br />
essentially an electric-motordriven<br />
machine<br />
Uses six barrels. Barrel<br />
life estimated at 50, 000<br />
rounds per set<br />
Design features well proven<br />
Controlled dispersion possible<br />
by modifying muzzle<br />
clamp<br />
Weapon is easy to soft<br />
mount. Soft mounting<br />
involves some feed system<br />
difficulties and weight<br />
