KEL-TEC RFB 7.62 mm HIGH EFFICIENCY RIFLE
INTRODUCTIONRFB stands for Rifle Forward ejection Bullpup.
This
concept, enhanced by an improved tilting block breech,
gains over a foot of additional barrel length over aconventional
rifle.
Furthermore, the stock and mechanism cross-section
is similar to a conventional rifle, in stark contrast to
thebulky bullpup rifles existing today.
DESCRIPTIONThe RFB is a gas-operated semi-automatic rifle in
7.62 mm NATO (.308 Win) caliber. It accepts standardFAL type
magazines. Barrel options include 18", 24",
and 32". Twist 10" or 11.25".
All controls are fully ambidextrous; the reciprocating
operating handle can be switched to either side. Thetrigger
mechanism has up to five individual
adjustment parameters. The dual action safety dis-connects the
trigger and blocks the hammer action.
A MilSpec picatinny rail is attached rigidly to thebarrel. No
iron sights are provided. A free floating,four sided picatinny
forend or bipod can be attacheddirectly to the barrel.

The improved ballistic efficiency of the RFB rifle derives
from a very long barrel increasing muzzle velocity over10% when
compared to similar size rifles.
The long range improvement is even more pronounced
with a heavier bullet at normal velocity. An M110 SASSshoots a
175 gr projectile at 2500 fps.The RFB will firea 210 gr bullet at
the same velocity, resulting in 65%more knockdown energy at 1000 m.
At the same
distance the wind deflection is reduced to 72%.This ballistic
performance is superior to a traditional 300Win Magnum and closely
approaches a 338 Lapua.

The Kel-Tec RFB has several new and innovative featureswhich are
here divided as sub-functions: Ballistic, feedingjection, firing
mechanism, and ergonomics.
BALLISTIC
The RFB barrel acts as a spine in the rifle. The compactreceiver
and tilting bolt close the breech. The sightingsystem is solidly
attached directly to the barrel. Forward othe sights the barrel is
free floating. Close to the chambergas pressure determines the
dimensions of the barrel.
Further forward, rigidity and mass are more pronounced the sake
of accuracy.
FEEDING
The hollow, trapezoidal, sheet metal bolt carrier is propelleby
a captive, adjustable gas piston. The return force is frotwo small
diameter coil springs with a high pre-load. Themass ratio of bolt
to bolt carrier is a favorable 1 : 4. The Rutilizes a proven FAL
metric type magazine.
EJECTION
Two symmetrical extractors are mounted on the sides of thbolt.
The extractors can rotate around a pivot point in theback and can
also move sideways to engage the rim in th
case. The extracted case is rotated upwards and on the wforward
fed into an ejection chute above the barrel. Thechute extends and
turns right to a forward opening where case is gently ejected.
