COMBAT MAGAZINE FLAP RELEASE
factory machine gun mag catch was an option that got left off
the semi-auto because of the trigger group block that HK
welded in to meet BATF approval. RDTS can precision install an
authentic HK FLAP MAG RELEASE on any HK, including the clones.
We install the flap mag release in the BATF approved manner.
This simply means that after installation your receiver block
remains intact and no through hole exists. If you ever had to
change mags on your HK quickly you probably have noticed how
you must remove your strong hand from the pistol grip position
to press the mag catch button to release the magazine while
repositioning the gun onto the left hand, Whew! what a pain!
With the COMBAT FLAPPER MAG RELEASE, which is on ALL HK
ORIGINAL Mg's, you simply grab the catch and magazine at the
same time with your left hand while your right hand never
leaves the ready position on the pistol grip! This is similar
to the AK style mag release method.
The affected area is the
left side of your receiver block which is milled back to its
original flat and appears as it did when your weapon was sent
to RDTS. The block is what the lower trigger group rests on to
the rear of the mag well. The rest of the weapon is unaffected
and you cannot tell the operation had been performed.
Note: After the machining and
installation of the Combat Flapper Mag Release we will touch
up with baked on HK Black.
Well try to explain the different styles. Friction Flapper was
normally found on G3ís and older HKís. It is flap that has an
angled contact surface that contacts a matching angled piece
inside the mag well on the shaft that your mag button is
pinned to. Sounds complicated but what it means is itís a
friction style. An angle forces another angle over to push the
mag catch out of contact with the magazine thereby releasing
it. Check out the picture. Roller
Style is an improvement over the
friction in that the flap contact area now has a roller or
cylindrical piece that contacts the angled piece on the mag
catch shaft. This reduces some of the drag associated with
angle to angle contact. Keep in mind if you buff out the older
style angle contacts you canít perceive any difference. And
the roller shaft is not as supported as the full beefier
angle. Its your call, we have both! Anti-Rattle refers to a
small leaf spring that is riveted to the flap itself. It is
available with either friction or roller flaps. Its purpose is
to keep the flap from rattling when a mag is in the weapon.
The leaf spring bears against the inserted mag causing the
flap to be pushed back against the rear part of the mag well
eliminating slack and therefore rattle. Without a mag in the
weapon the flap still rattles.
When RDTS installs a
magazine Flapper release on your weapon it doesnít rattle! We
are not an assembly line so we can take the time to precision
fit the contact areas. We also buff the angle contact areas
and the bottom of the mag catch itself that bears against the
slot it sets in. Through experience we have seen these
procedures will give our customers a smooth and wear free
assembly no matter what style they use.
