Editing BT Paintball


'''BT Paintball''' (later marketed as '''Battle Tested''' or '''Empire Battle Tested''') was an American [[paintball equipment]] brand established by [[Ben Tippmann]] in 2004. The company specialised in mechanical and electronic [[paintball marker]]s, accessories and protective equipment designed primarily for recreational, woodland and scenario paintball.[1]

Its principal products included the [[BT-16]], [[BT-4]], [[BT Delta]], [[BT-4 ERC]] and [[BT TM-7]]. The brand later became part of the [[KEE Action Sports]] portfolio and was marketed through [[Empire Paintball]].[2][3]

== History ==

=== Establishment ===

BT Paintball was established by Ben Tippmann, who had previously worked for [[Tippmann Pneumatics]], the American manufacturer founded by members of the Tippmann family.

During the late 1990s and early 2000s, Ben Tippmann was involved in promoting Tippmann equipment at tournaments, scenario games and trade shows.

He subsequently left the company and established his own paintball equipment business.

BT Paintball appeared in 2004, initially marketing a range of tactical and scenario-oriented markers and accessories.[1]

The original BT name was associated with Ben Tippmann, while the brand subsequently adopted '''Battle Tested''' as its commercial identity.[4]

=== BT-16 ===

The company's first major marker platform was the [[BT-16]], a mechanical semi-automatic marker developed for woodland and scenario paintball.

The BT-16 used a blowback operating system and incorporated military-style external components.

Its construction was designed to support the attachment of accessories, including shoulder stocks, sighting equipment and barrel assemblies.

A detailed technical review published by [[WARPIG]] in September 2005 examined the BT-16 Elite, including its mechanical operation, maintenance requirements and firing performance.[1]

The review documented the marker's open-bolt blowback mechanism, removable grip frame, interchangeable barrel adaptor and accessory mounting arrangements.

=== BT-4 series ===

BT subsequently developed the [[BT-4]], which became the foundation of an extensive range of recreational and scenario markers.

The BT-4 was a .68-calibre mechanical semi-automatic marker incorporating a blowback operating system and removable barrel.

It was designed to accommodate numerous external accessories, allowing customers to configure the same basic platform with different stocks, barrels, foregrips and tactical components.

The original product range included the BT-4 Combat, Assault and Rental models. A manufacturer's manual dated July 2005 documents these configurations.[5]

Additional models and equipment packages followed, including the Delta, Ironhorse, Banshee, S.W.A.T. and ERC.

These products frequently shared the same underlying BT-4 mechanism, differing principally in their external equipment and accessory packages.

=== Expansion of the product range ===

During the late 2000s, BT expanded beyond conventional mechanical blowback markers.

The company developed the BT Electronic Grip Frame, allowing compatible mechanical markers to operate using electronically controlled firing modes.

The [[BT Rip Clip]] loader was also introduced as a side-mounted, motorised feeding system.

In December 2007, contemporary retailer reporting documented the BT-4 ERC, which combined the BT-4 Combat platform with an electronic trigger frame, Rip Clip loader and Apex barrel system.[6]

The company also introduced additional tactical-style marker configurations, including the Delta Elite.

=== TM-7 ===

In 2008, BT introduced the [[BT TM-7]], an electronic marker using internal technology related to the [[Invert Mini]].

Unlike the company's earlier mechanical markers, the TM-7 incorporated a compact electronic pneumatic firing system.

Its external design was inspired by the Heckler & Koch MP7 submachine gun, incorporating a folding foregrip, integrated stock and side-mounted firing-mode selector.

Contemporary reporting from the [[2008 PSP World Cup]] documented the TM-7 at the BT Paintball trade stand.

The marker had been released earlier that year and was exhibited alongside the company's other tactical equipment and accessories.[7]

=== Empire Battle Tested ===

BT subsequently became part of the wider paintball equipment portfolio associated with National Paintball Supply and KEE Action Sports.

By 2010, the brand was being marketed under the Empire Battle Tested name.

Manufacturer documentation identifies Battle Tested as a trademark of Empire Paintball and describes Empire as a brand of KEE Action Sports.[8]

The BT product range continued under Empire, including the BT-4 series and subsequent electronic and tactical marker designs.

Later products included the [[BT TM-15]], [[BT Omega]], [[BT SA-17]], [[BT D*Fender]] and the BT-4 Slice series.

These models are documented through the manufacturer's technical manuals and support archives.[3]

The available records do not establish a single date on which all Battle Tested products were discontinued.

The [[VintageRex]] historical marker database lists five principal BT models under the manufacturer heading ''BT - Ben Tippmann''.[2]

The VintageRex database records 2006 for the BT-4 and 2008 for the ERC, although contemporary documentation establishes that both were marketed earlier than those catalogue dates.[5][6]

=== Additional models ===

Other BT and Empire Battle Tested markers documented through manufacturer manuals and contemporary product records include:

* [[BT-4 Combat]]
* [[BT-4 Assault]]
* [[BT-4 Rental]]
* [[BT-4 Delta Elite]]
* [[BT-4 Ironhorse]]
* [[BT-4 Banshee]]
* [[BT-4 S.W.A.T.]]
* [[BT-4 Slice]]
* [[BT Omega]]
* [[BT TM-15]]
* [[BT SA-17]]
* [[BT D*Fender]]

Several BT-4 configurations used the same basic mechanical platform and differed primarily in their accessories and external appearance.

== Technology and accessories ==

=== Mechanical blowback system ===

The early BT-16 and BT-4 markers used mechanically operated blowback systems.

Gas pressure propelled the paintball while also driving the hammer assembly backwards to recock the marker.

The system allowed semi-automatic operation without electronic controls.

BT incorporated removable grip frames, interchangeable barrel systems and components intended to simplify cleaning and maintenance.[1][5]

=== Electronic Grip Frame ===

The BT Electronic Grip Frame was an aftermarket and factory-installed accessory for compatible BT markers.

It provided electronically controlled firing modes, including semi-automatic and programmed firing sequences.

The system was incorporated into the BT-4 ERC equipment package.[6]

=== Rip Clip loader ===

The '''BT Rip Clip''' was a side-mounted electronic paintball loader designed for BT markers.

It used a sound-activated motorised feed system incorporating technology associated with the HALO loader range.

The loader positioned the hopper beside the marker rather than directly above it, allowing an unobstructed sight line over the receiver.

Its operation and installation are documented in the manufacturer's technical manuals.[3][6]

=== Apex barrel ===

BT marketed the '''Apex''' barrel, which incorporated an adjustable device at the muzzle intended to alter the spin and trajectory of fired paintballs.

The design allowed players to adjust the direction and extent of the spin effect.

The Apex barrel was available as an accessory and was included with certain factory marker configurations, including the BT-4 ERC.[6]

=== Tactical accessories ===

BT marketed additional accessories designed for woodland and scenario paintball.

These included:

* Adjustable and fixed shoulder stocks.
* Tactical foregrips.
* Barrel shrouds and extensions.
* Sight rails and mounting equipment.
* Magazine-style expansion chambers.
* Marker carrying systems.
* Pod harnesses and tactical vests.

The accessory range allowed players to modify existing BT markers rather than purchase entirely different internal marker platforms.[5][7]

== Relationship with Tippmann ==

BT Paintball and [[Tippmann Sports]] were separate businesses despite their shared connection through Ben Tippmann.

Their products competed in the recreational and scenario paintball markets.

BT's early mechanical markers used operating principles similar to those found in Tippmann's established blowback models.

The companies became involved in a legal dispute over intellectual property and branding during the mid-2000s.

A federal case filed in November 2004 identified Tippmann Pneumatics and related businesses as plaintiffs, with BT Paintball Designs, Ben Tippmann and National Paintball Supply among the defendants.[9]

The litigation should not be interpreted as proof of infringement without reference to its findings or settlement terms.

BT continued marketing its marker range under the Battle Tested identity.
