Accessories
1. Stocks – The APC300 comes with a folda-
ble and length adjustable stock. As an op-
tion a clamp-on check rest, to add an extra
12 mm in case special optics (e.g. night
vison) with a higher mount are chosen, is
available. The helmet stock will enable the
operator to use the APC while wearing a bal-
listic face visor, a protective mask or SCUBA
gear. The skeleton stock is foldable but not
length adjustable. The retractable stock (bot-
tom) does not increase the width of the gun
when stored.
Q: Why not make it easy and produce a weapon on an M4 platform.
A. The AR15/M4 platform was first introduced in 1958. It has ser-
ved well for over fifty years but all major armies that have the M4 are
looking for the next generation rifle to replace it. We feel that by not
doing the extra work on the APC we would be dooming our custo-
mer to perhaps ballistic advancement but mechanical obsolescence.
Q: How often does the weapon and suppressor need to be cleaned?
A: As with all weapons that are used for real life combat, it is
recommended to clean your weapon after every shooting session.
The silencer however needs only periodical cleaning, we recom-
mend cleaning it after 500 to 1,000 rounds fired.
Q: How loud is the .300 Whisper or the .300 Blackout compared to other sub-
sonic cartridges? Please refer to the table listed below.
Q: Is there a way to tell the difference between a subsonic and a high velocity
round in .300 Whisper/.300 Blackout?
A: Yes, the subsonic rounds have a blue primer
Q: Will .300 Whisper cartridge function in a .300 Blackout chambered
weapon and visa versa?
A: A .300 Blackout cartridge will function in a weapon chambered
for .300 Whisper. It may not be the same the other way around. This
depends on the chambering of the weapon. The APC300 will func-
tion perfectly on each caliber.
Q: What is the difference between the .300 Whisper and .300 Blackout
cartridge?
A: Even so both cartridges look almost identical; there are a few
very technical points to discuss on this subject. But the main points
to remember are: The .300 Whisper from is CIP approved but not
SAAMI certified. The .300 Blackout SAAMI certified but not CIP
approved.
Q: What is the difference between SAAMI and CIP?
A: CIP (Permanent International Commission for Firearms Testing) is
the standard used in Europe by 14 countries and accepted by many
nations worldwide. SAAMI (Sporting Arms and Ammunition Manu-
facturers’ Institute) is used in the United States. There are technical
differences on how ammunition is tested.
Q: The .300 Whisper as well as the .300 Blackout are designed as subsonic
rounds. How does the supersonic round perform?
A: The supersonic round is perfect for police work up to 300 meters.
Penetration, accuracy and terminal ballistics are outstanding.
Q: How reliable is the APC300 if loaded with sub- and supersonic ammunition?
A. The operator will feel a difference in recoil, however the action of
APC300 is especially designed to work in full auto mode with both
cartridges, even if you load them alternating in the magazine.
Q: Will the .300 Whisper/.300 Blackout be able to penetrate body amour?
A: Yes, depending on the type of bullet even up to level IIIA.
Q: How do the .300 Whisper/.300 Blackout react if shot on a windshield?
A: We have tested all four .300 Whisper cartridges (2 subsonic,
2 supersonic) from RUAG on windshields with soap behind it, accor-
ding to German Police testing standards. Bullets are not deviated
passing through the windshield and transfer an impressive amount
of energy in the target.
Q: Why is the .300 Whisper/.300 Blackout better as a subsonic round than a
.308 Win (7.62 x 51 mm)?
A: Subsonic ammunition uses significantly less powder than high veloci-
ty counterparts. When this reduced powder volume is ignited in a large
capacity case (eg .308), it may ignite inconsistently, thus producing
inconsistent velocities & ballistics. The smaller .300 Whisper case is
more suited to reduced powder volumes & hence provides more consis-
tent ignition.
2. BT Weapon Mounted Light – This state of the
art tactical illuminator was designed from
the very beginning following B&T specifica-
tions by the well known INFORCE company
as a weapon light not as a handheald flash-
light modified to weapon use. It is very light-
weight (100gr) in spite of the 100 % solid
state, shock proof design. It produces a blin-
ding 125 Lumens of output. The light is small
in size (10cm length), does not require ca-
bles which can easily break and is activated
with a simple pressure switch designed to be
easy to operate with gloves.
3. Brass Catcher – This accessory is an ab-
solute must when working in, on or around
vehicles, ships and aircraft. The contain-
ment of the hot brass is important wherever
conbustible materials are present. The B&T
designed brass catcher mounts directly on
the right side NATO Accessory Rail (NAR).
It pivots easily and quickly for manipulations
and safety inspections. On the range a brass
catcher makes cleaning up quick and easy.

4. Sound Suppressor – Due to the many advan-
tages they offer, suppressors are a must with
modern police and military tactics. As
learned in the actual assymetrical conflicts a
good suppressor will bring safety and secu-
rity to the user. Some of the direct noticeable
benefits are sound and muzzle flash reduc-
tion, command & control, friend / foe identi-
fication and of course hearing protection.
The B&T suppressor can be attached to the
APC300 within seconds and without any
tools. It does not degrade accuracy, but
rather in many cases improves it.
5. Quick Detachable Vertical Foregrip – Provides
the shooter a stable shooting grip and keeps
the support hand away from the muzzle.
There are several versions with or without an
retractable bipod available.
6. Bipods – In order to archive maximum accu-
racy, B&T offers a variety of foldable teles-
copic bipods, which could be hinged down
when necessary.
