BestLine International Research Inc. has developed a full line of synthetic lubricating and sports
products with patents in the United States, Europe, South Africa, Japan and Australia with
pending applications in many countries around the world. One of its products is a one-step gun
cleaner and lubricant. The goal was to develop a full-synthetic product that would, in one step.

After development, Bestline's Soldier's Choice synthetic gun cleaner and lubricant was tested by
a County Sheriff's Department and competitive shooters.
The evaluations were conducted using both handguns and automatic rifles. Each pistol or
revolver was fired a minimum of 2,500 rounds per month for seven months totalling a minimum
of 17,500 rounds fired per handgun. There were no malfunctions whatsoever due to loss of
lubricity or fouling. The make, model and caliber of the handguns used varied, but included
several different manufacturers, different models, and different calibers.
The evaluation also included six newly purchased M16 rifles. The test was conducted over a ten
day period with each rifle firing 500 rounds of military spec ammunition per day, with a total of
30,000 rounds expended. No malfunctions of any kind involving lubricity or fouling were
encountered during the evaluation of BestLine's "Soldier's Choice" Gun Cleaner and
Comments from the shooters included:
BestLine is the best and most effective lubricant any have ever used.
The pistol, subsequent to the initial cleaning and lubrication, ran smoothly and
without malfunction for over 1100 rounds without cleaning.
The pistol was much easier to clean as it was not as dirty as when previously used
in the same sport, and the barrel had accumulated less fouling;
When his pistol magazines, which are required to drop free from the pistol to the
ground, the range where they shoot is sand, hit the ground, he noticed that those magazines
that had been cleaned and lubricated with "Soldier's Choice" did not collect sand and dirt or
malfunction as they usually did prior to the use of BestLine.
The shooters found that if they disassembled their firearms, cleaned them with a degreaser or
Windex with Ammonia, and then applied BestLine as per instructions, the pistols functioned
flawlessly and were much easier to clean, and easier to keep clean because there was
significantly less build-up of dirt and gunpowder fouling.
The above were informal "hands on" tests by avid shooters. In addition, the product has been
subjected to a number of formal objective tests, Which you can find in the TEST & PROCEDURE section of the website
Friction Heat and Wear
Through mechanical testing, the lubrication components of "Soldier's Choice" were evaluated to
measure its effect on friction, heat and wear. On average, the product demonstrated an ability to
reduce friction and heat by well over 25%. This substantial reduction in friction can have a
profound effect on maintaining the accuracy of automatic or semi-automatic weapons.

Product Comparison with Break Free CLP
Break Free is widely used by both military personnel and civilians. It is widely believed
that it provides excellent lubrication. To compare, BestLine put it to the test.
The test was conducted using a standard
"cross-axis" machine commonly referred to as a
"bench test." The machine holds a "test bearing"
against and perpendicular to (or across) the axis of
a rotating bearing. The metal in the rotating
bearing is considerably harder than the metal in
the "test bearing." Force applied to a torque
wrench determines how much pressure exists
between the two bearings. The damage to the "test
bearing" has a direct inverse relationship to the
lubricant being tested; specifically, the better the
lubricant, the less the damage.
Break Free's instructions state, "For best results, allow to cure for 2 hours." The
directions also state, "Allow a few minutes or more (even overnight) for penetration..."
Following those instructions, both the test bearing and the rotating bearing were treated with the
"CLP" and allowed to cure for 24 hours prior to testing. BestLine's Soldier's Choice,
immediately before the test, was applied and wiped with a paper towel.
The test consisted of placing ten (10) pounds of weight on the torque wrench and running
the machine for 10 seconds. The damage to the test bearings provides clear results:
TEST I: With Break Free CLP. The wear
scar shown was from 10 seconds of running
with the pressure of 10 pounds of weight.
TEST II: With BestLine's Soldier's
Choice. The wear scar shown was from 10
seconds of running with the pressure of 10
pounds of weight.
TEST III: With BestLine's Soldier's
Choice. The wear scar shown was from 60
seconds of running with the pressure of 10
pounds of weight. This would be the same
as shooting hundreds, if not thousands, of
rounds with no jamming or other
malfunction due to lack of lubrication.
BestLine's Soldier's Choice Gun Cleaner and Lubricant is able to provide the best
lubrication available to keep your firearm operating smoothly and trouble free under the most
