Brno Combo new model

Zbrojovka Brno began manufacturing of the Brno 800 -series combination gun in early 2005. In 2007 its production went under the Czech CZ group. From this date on the weapon was known as CZ BO 802. The new Brno Combo combination gun was developed during the years 2013-2014, based on the previous 500 and 802 series combination guns. The new Brno Combo was introduced in 2014 and it replaced the production of the previous model.

Configuration

The 600 mm long barrel pair of the Brno Combo combination gun is made of cold-forged high-quality barrel steel. The rifle barrel is free floating (Thermostabil) and the front mounting of the barrel also allows the barrel to expand lengthwise. The metal strip between the barrels is merely an aesthetic element, which, in a way, mimics the usual “barrel-to-cross solder-list”. In addition, the barrels have a one-piece, manual case ejector. The barrels have blued surface finishing.

12/76 -caliber shotgun barrel has a fixed ¾ -choke (IM = Improved Modified). The marking indicating this, is on the left side of the shotgun barrel, "Choke Ø 17.8", which means the diameter of the barrel bore of 17.8 mm.

The shotgun barrel has been a test shot at 1320 bar pressure, which means it will also withstand the use of cartridges loaded with steel pellets. A CIP proof marking and a French lily -stamp are placed on the internal surface of the lock frame, as evidenced by steel shot proof. In addition, "Steel Shot Proofed" and "Testing pressure 1320 Bar" are on the right side of the shotgun barrel. The left side of the shotgun barrel is marked "Ø 18.3", which means the diameter of the post-cone bore of 18.3 mm. The bore is smaller than average, which increases the barrel pressure and, at the same time, the projectile’s muzzle velocity and penetration capacity.

The caliber of the rifle barrel on the under the shotgun barrel, is optionally: .308 Win, .30-06 SPRG, 8x57 JRS or 9,3x74R. On the left side of the rifle barrel (. 308 Win) there is a barrel’s small-bore marking (Ø 7.62 mm), i.e. the diameter measured between the rifling bar over the opposite riffle bar.

The Trigger mechanism is equipped with two triggers, the front trigger is for the rifle barrel and the rear trigger for the shotgun barrel. The trigger on the rifle barrel is adjustable set trigger, which is switched on by pushing the trigger forward. The trigger pull of the rifle barrel is adjustable between 3-5 N. The trigger mechanism has an automatic safety feature that automatically turns on whenever the gun is closed or is cocked. The automatic safety device push-latch is positioned, in the traditional way, in the neck of the stock.

The weapon has a red fiber optic front sight, which can also be adjusted. The new design, fixed rear sight (Hud Sight), in turn, allows for better visibility to the target.

You can also install riflescope on the Brno combo. For this, an 11 mm salmon tail rail is on top of the lock frame. On the weapon, present of this site, has a fixed Kozap riflescope mount. The Kozap riflescope mounts are also available as a quick detachable model.

Most parts of the gun are manufactured by CNC machining. The folding lever (Top Lever) and trigger guard are made by a precision casting and the surface treatment of these parts by blueing.

The low-profile locking frame is made of steel by CNC machining. The outer surface of the lock frame lightly sandblasted and then nickel-satin coated. The sides of the lock frame are laser-engraved hunting-related engravings. On the left side of the lock frame the theme of the engraving is wild boar and hunting dog and on the right side two roe-deers, placed in the forest landscape.

Ergonomically designed stock with Bavarian styled cheekpiece is made of high-quality Turkish walnut wood. Stock grip texture has been driven by a braid-type of roughening and surface treatment is oil finish. The stock recoil pad is made of a black rubber alloy and has a logo of Zbrojovka Brno, with a Z in the middle of the rifling.

Aligning the rifle barrel

The sights are regulated at the factory at 50 meters, so that when firing a shotgun barrel with the Sellier & Bellot Special Slug cartridge, the rifle barrel will shoot roughly at the same point. The rifle barrel alignment can be adjusted by using two adjusting screws, which are in the adjusting mechanism between the shotgun and the rifle barrel.

Each weapon is attached with a test shot results from the factory. Test includes, first test is two shots with a rifle barrel and one slug shot with a shotgun barrel and a second test is two shots with a rifle barrel and one shot with shotgun barrel, using the Sellier & Bellot pellet cartridge.

The adjusting- and locking screws between the barrels, on both sides of the barrels


When you want to adjust the alignment of the rifle barrel of the Brno Combo combination gun, you must first loosen the M2x4-size locking screws (Ø 0.9 mm) on each side of the barrels at the adjusting mechanism. When the screws are unscrewed about 0.6 to 1 mm, the lock is unlocked. When the adjusting screws are turned clockwise the barrel aligning will move up and screws turned counter-clockwise the barrel aligning will move down. After barrel adjusting the locking screws should be tighten properly so that the barrel alignment won’t change by the recoil force when shooting.

Factory markings

The weapon has multiple different manufacturer's markings. The model designation of the gun is placed on the left side on the chamber end of the shotgun barrel. The serial number can be found under the folding lever and on the underside at the chamber end of the rifle barrel. The manufacturer's logo and manufacturer's name Zbrojovka Brno can be found on the right side of the chamber end of the shotgun barrel and on the underside of the locking frame. The CIP proof marking, as well as the French lily -label, are placed inside the lock frame.

Zbrojovka Brno

The weapons factory Zbrojovka Brno was founded in 1918 at the end of the First World War. The weapons factory in Brno had before been an Austro-Hungarian artillery repair shop, but after Austria-Hungary’s breakup to several independent states, the factory became the new Czechoslovak state’s state-owned weapons factory.

At the beginning the Brno's weapons factory repaired a variety of military rifles. At first to the production came the Austro-Hungarian era Mannlicher rifle, which was later replaced to manufacture the German Mauser rifle. In 1924 the production was expanded and the rifles, along with the production of the machine guns. During the Second World War, the plant produced mostly Mauser-type weapons for use by the German Army. However, the weapons production plant slowly faded into the 1980, while production continued until 2003 when the plant went bankrupt. The plant was acquired in 2007 by the multinational J&T Finance Group.

Today Zbrojovka Brno brand is part of the CZ-Group Czech. Today the Brno brand makes hunting rifles and composite weapons.
