Robar PolymAR-15Ti

R

obar Guns, a company usually
associated with specialty firearm
finishes and plating, recently
introduced a lightweight variant of the
AR-15. Weighing less than 5 lbs., the
PolymAR-15Ti is a mixture of old technology and new materials assembled
with a great degree of attention to
detail. Featuring a 1-m.o.a. accuracy
guarantee, the Robar gun also possesses the reliability needed for law
enforcement, security, home defense
and hunting.
The key to the PolymAR-15Ti's
light weight is its polymer upper
and lower receivers. Manufactured
by Kaiser Shooting Products, the
receivers are molded with a proprietary blend of polymers specially
compounded to provide strength. The
upper and lower receivers together
weigh merely 10 ozs.-compared to
around 16 ozs. for conventional aluminum receivers. Kaiser reinforces its
receivers, molding aluminum inserts
into the polymer at critical areas such
as the receiver ring, hammer and trigger pin locations, and the barrel nut

area. The upper receiver does not possess a forward assist, but does have
a polymer ejection port cover that is
laser-engraved with an American flag
and the legend "556 NATO".
Another significant weight savings
comes from Robar's titanium bolt carrier, which, at 7.7 ozs., weighs about
30 percent less than a conventional
bolt carrier group. The bolt itself is
plated with Robar's NP3 finish-a
nickel-Teflon coating that is self-lubricating and extremely easy to clean.
Robar uses a roller cam rather than
the traditional rectangular cam, which
reduces drag and friction, and provides
smoother unlocking of the bolt.
In addition to the bolt carrier, the
castle nut, takedown pins, receiver
end plate, barrel nut, gas block,
magazine catch and button, and the
selector/safety are all machined from
titanium. Titanium is roughly half the
weight of steel yet three times stronger than aluminum and is extremely
corrosion-resistant. The downside to
this alloy is that it is more expensive
than aluminum or steel and also more
difficult to machine.
Robar uses a Faxon Gunner barrel
on the PolymAR-15Ti. The barrel has
a 5.56 mm chamber so it can safely
fire both .223 Rem. and 5.56x45 mm
NATO cartridges without pressure or
extraction issues. Our test sample

had a barrel length of 14.5" with a
Bravo Company Mfg. 1.5" titanium
compensator pinned and permanently
welded to meet the 16" minimum
barrel requirement. The barrel is
rifled with 1:8" twist, has a midlength gas system and is Melonitetreated for wear and corrosion
resistance. The low-profile titanium
gas block is covered by the BCM 13"
free-floating, KeyMod handguard for
a sleek, uncluttered profile.
Bravo also supplies the sixposition collapsing stock used on
the PolymAR-15Ti. The Gunfighter
stock Model O is silent in operation,
slides between positions easily and
locks securely. The pistol grip is
also a BCM part and has excellent
ergonomics. It is of tapered design-
thinner at the top and fatter at its
bottom-and is textured for a secure
grip. At its bottom is a hinged trapdoor, and Robar uses this storage
area to include an extra firing pin
and a Magpul MBUS sight tool.
Robar outfits the PolymAR-15Ti with
a Sionics Enhanced Mil-Spec Trigger,
which is also plated with an NP3 finish.
Our test sample's trigger broke cleanly
at 5 lbs. To maximize the carbine's accuracy potential, we mounted a Trijicon
5-20X 50 mm AccuPoint scope on it,
which is certainly far more scope than
needed for practical field applications

The Robar PolymAR-15Ti's Bravo Company Mfg. Model O buttstock can be adjusted to
six different lengths due to the gun's use of a carbine-style buffer extension.
