United Defense Mfg Corp’s S5-DGIS and S5-PVAR rifles are variants of the M16 and M4 rifles. The “S-series” are the semi-automatic models that can be purchased by active AFP, PNP and LEA individual personnel with proper LTOPF and proof of Duty Detail Order. These rifles are chambered in the time-tested 5.56 NATO round (5.56 x 45mm) and designed to hit point targets at 500 meters (MER). The S5 takes after the M4 and M16 battle rifle designed by Eugene Stoner. It uses two different action designs, the Direct Gas Impingement System (DGIS) and the patented Pneumatic Valve and Rod (PVAR). The DGIS is the simpler design between the two as it has less parts and uses the hot gases coming from the gas port of the barrel and through a gas tube the hot gases are rammed into the bolt carrier group to cycle the round. On the other hand, the Pneumatic Valve and Rod (PVAR) gas-piston or simply the patented PVAR™ system or Pneumatic Valve and Rod System is a “bare bones, no frills and very simple” designed gas and piston operating system that utilizes a combination of gas and mechanical energy for a more effective and reliable cycling of the weapon. The valve has three (3) settings: With the use of sound suppressor, without sound suppressor and bolt action mode. The PVAR design prevents hot and high-pressured gases from reaching the bolt assembly, the one-piece bolt carrier group and the chamber. This results in a cleaner and reliable operation, as well as minimal maintenance even in the most rugged environments such as jungles, deserts, snow and salt-water conditions. This means reduced cleaning time and overall LONGER rifle life span. The PVAR’s simplified parts and mechanism allows reduced recoil and reduced muzzle rise, which enables the firer to refocus instantly on the target for each and every round fired! The DGIS uses a lightweight thermoplastic handguard and the PVAR uses a milspecs 1913 picatinny quadrail handguard which matches with a military standard 1913 picatinny flat top rail upper receiver. The handguard is held securely only at the barrel extension which allows the barrel to “float” and reduce barrel vibration while in battery. This allows for greater accuracy and consistency. As designed, the barrel of the S5-PVAR does not touch any part of the entire length of the handguard except at the barrel extension. The barrel of both the S%-DGIS and the S5-PVAR comes in different lengths: 7.5, 10.5, 11.5, 14.5 and 20 inches.

Q – What type of ammo can your rifles use?
A – For the caliber 5.56 NATO, it can use any brand of M193 or M855 ammo.
Q – What are the maximum effective ranges (MER) of your rifles?
A – For the caliber 5.56mm NATO, 500 meters for the 14.5 inches barrel.

Maximum Effective Range (MER)
*To borrow a definition, MER is “The maximum range within which a weapon is EFFECTIVE against its intended target”. This would translate into the maximum range that the weapon could effectively put a man out of action.

Q – What type of barrels do you use?
A – We use only Stainless Steel 410 or 416 Premium or Carbon Steel 4150 in ordnance grade and duly certified from source or origin of the blanks as raw materials.
Q – Do you manufacture your own barrels?
A – Yes we do. We manufacture them from barrel blanks supplied to us by Dikar-Bergara from Spain. We are the Exclusive Distributor of Dikar-Bergara for all their products, barrel raw materials (blanks) including their bolt-action rifles in the whole of Asia-Pacific.
Q – What is so special about your UDMC barrels?
A - The Bergara cylindrical blanks are made from the finest 4150 carbon steel, SS-410 and SS-416 Premium stainless steel, used in the ordnance, aerospace and defense industries.
A - If other suppliers will claim that their barrels are 4150, SS-410, SS-416, only a Certificate of Chemical and Mechanical Analyses can determine its quality. UDMC’s AISI 410 and 416 Stainless Steel PREMIUM ordnance grade barrel has traces of Vanadium, Nickel and Molybdenum which are not found on a standard AISI 410 and 416 stainless steel barrels. The net effect is that the United Defense-Bergara barrels have a yield strength of 780 MPa (versus 275 MPa of an ordinary AISI 410 and 416) and a tensile strength of 920 MPa (versus 517 MPa of an ordinary AISI 410 and 416). In terms of toughness, a UDMC barrel is 73 Joules (versus 34 Joules of an ordinary AISI 410 and416).
A - If required by the customer, we can issue a certification that the barrel installed on his or her UDMC rifle is a United Defense-Bergara PREMIUM Ordnance Grade barrel.
A - The optimum combination of high hardness, yield strength, and tensile strength, along with the correct toughness, allow UDMC barrels to withstand the generated pressures when the rifle is in battery, even with powerful rounds such as the .30 caliber or the .50 caliber precision rifles.
A - UDMC barrels, compared with other stainless steel barrels in the firearms industry, are very hard steel which increases the mechanical properties of the barrels and it is fair to say that this is one of the best insurance from the safety point of view of a barrel. In addition to this, one of the differences of UDMC barrels is the small grain size of its molecular structure thus guaranteeing excellent toughness. The homogenous microstructure during hardening and tempering provides a uniform hardness along the bar, producing a very uniform rifled bore, which is the key to accuracy of a barrel. The heat treatment, in combination with the precise deep hole drilling, honing and button rifling process results in a uniform finish of the bore under 0.0008 inches. The stress relieving heat treatment on the other hand, after the button rifling process, protects the bore from inside deformation after the tapering of the barrel. It also helps protect the barrel from heat generated after continuously firing several hundreds of rounds.
A - The same level of quality speaks of the UDMC-Bergara 4150 carbon steel barrels in durability, safety and accuracy.
A - Finally, the high chromium content of UDMC-Bergara barrels provides a good corrosion resistance to it.
Q – What raw materials do you use for the rifles?
A – We use T6-7075 for the upper and lower receivers, T6-6061 for the handguard (or thermoplastic) and buttstock tube. For metal parts, we use only 4140, 4150 and MIM-S7 for the small parts. Our barrels are made either of Stainless Steel 410 or 416 Premium or 4150 carbon steel, Premium ordnance grade which has contents of Molybdenum, Nickel and Vanadium not found in other barrels which makes it double the tensile strength versus other barrels in its category.
