As with gun cartridges, D&F first introduced the DF6PD, which fires 6mm countersunk rounds.

As can be seen from the codename, this is not a submachine gun in the traditional sense, but a weapon for individual self-defense, but it is different from PD in the usual sense.

To put it simply, the DF6PD is more like a carbine like the M4.

According to D&F, the DF6PD is used to replace the M4 carbine and AK assault rifle, and all the performance exceeds the M4 carbine.

Of course, this is due to the head-buried bomb.

In the regular army, the DF6PD can fully serve as the main force and become the main battle weapon in the hands of the infantry, coping with the needs of engagement within 600 meters.

By replacing the short barrel, the DF6PD can replace the submachine gun as a personal defense weapon for non-combatants.

Thanks to the powerful performance of the countersunk bullet, the DF6PD not only has the portability of a submachine gun, but also surpasses the power of carbines and assault rifles.

In the words of D&F's advertisement, having DF6PD is sufficient.

Of course, D&F company focuses on recommending DF6PD, which has a lot to do with its price, that is, DF6PD is the cheapest automatic firearm that fires countersunk shells, the base price of mass purchase is only $3,000, and the full-state model equipped with a reflective optical sight and a second barrel is only $4,200, and the daily maintenance cost is comparable to that of the M4, and the economic benefits of mass equipment are extremely considerable.

As for performance, it's actually quite enough.

According to D&F's advertisements, the DF6PD is comparable to H&K's HK650 in terms of performance, far surpassing existing small-caliber rifles.

In terms of price, it is naturally much cheaper.

The HK650 can be purchased in bulk at up to $5,500 and the full-state version can reach $8,000, and the daily maintenance costs are extremely high.

DF6PD can be made cheaper, the key is still the bullet.

D&F's countersunk bullets are made of metal cartridge housings, so the design requirements for the firearm are much lower, and there are no special requirements for the production process.

The problem is that the overall performance of the 6mm countersunk is worse than that of H&K's 6.5mm countersunk.

Actually, there's nothing surprising about that.

The metal shell is heavier, occupies a larger specific gravity, and while maintaining the same mass, the 6-mm head-sinking shell will definitely have a smaller charge.

Of course, judging from the actual needs, the DF6PD that launches 6mm countersunk shells is indeed enough.

It's just not the point.

The second type of firearm presented at the press conference was the DF8SMG.

According to D&F's code rules, "SMG" is an abbreviation for "Squad Automatic Weapon".

Not a rifle, not a machine gun, but a "squad automatic weapon", what does it mean?

In fact, this is what makes the DF8SMG unique.

Typically, the infantry's main combat weapon is a rifle, while the support weapon assigned to an infantry squad is a light machine gun such as the M249.

Infantry squads are also issued with precision marksman rifles such as the M21 if needed.

DF8SMG brings all three together.

For this purpose, the DF8SMG is available in three barrel lengths, and can be used as a rifle, machine gun, and sniper rifle by changing the barrel.

On the DF8SMG, the only thing that can be changed is the barrel, and the other components are completely common.

If these features are not distinctive enough, or not unique, then the DF8SMG can fire two lengths of 8mm countersunk without any changes, just by adjusting the two devices, which is absolutely unique and unprecedented.

To put it simply, the DF8SMG's ammunition feeder and bolt are both adjustable in two gears.

When used, the soldier only needs to change the gear between the feeder and bolt to fire the corresponding length of bullets.

The ammunition feeder is better to say, and it can be solved with a length adapter.

The key is the bolt.

To this end, the DF8SMG adopts the "Suspension Adjustable Bolt Engine" designed by Zhao Yu and owned by D&F for which D&F has full intellectual property rights.

It was this bolt that extended the design work of the DF8SMG for almost half a year.

As for the specific principle, because it is a trade secret, D&F did not disclose it to the public, only emphasizing the advanced performance of the "suspended adjustable bolt machine".

Of course, the main model of the DF8SMG is a rifle type that uses a normal barrel and fires short bullets.

The machine gun version, which uses a heavy barrel and fires long rounds, is only available in limited quantities.

As for the sniper type, which uses an extended heavy barrel and can fire both short and long bullets, it is customized according to the needs of customers.

However, D&F can also produce special DF8SMGs according to customer requirements.

For example, customers can use non-adjustable ammunition feeders and bolts as long as the rifle type, thereby reducing the purchase price and reducing the difficulty of daily maintenance.

Customers can also purchase the all-state type to equip special forces, after all, special forces have more operational needs.

All in all, D&F is completely focused on the needs of its customers.

With two types of bullets to choose from, as well as three barrels to choose from, plus sights, mufflers and other accessories, the DF8SMG is simply an all-round firearm.

According to D&F, the DF8SMG is capable of replacing all squad automatic weapons except pistols.

In addition, it can replace most of the battalion and company-level direct-fire support weapons, i.e., general-purpose machine guns and heavy machine guns.

The benefits are obvious.

After equipping the DF8SMG, only two types of ammunition need to be provided for the troops, and daily maintenance can be carried out centrally, which greatly reduces the pressure on logistics support.

You know, just in the past, there were several types of guns and ammunition used by units fighting below the battalion level.

As for firearms, there are more than a dozen kinds, and it is a big trouble to carry out daily maintenance and provide necessary spare parts for these firearms.

Replacing a dozen guns with one gun and a dozen with two bullets is definitely a huge step forward.

According to D&F's propaganda, in the current combat environment, a short bullet of 8mm countersunk is sufficient, and there is no need to purchase a second type of ammunition.

In this way, the burden of logistics support can be further reduced.

In addition, D&F is developing a carbine that fires 8mm countersunk rounds.

Obviously, when the time comes, even DF6PD will not be needed.

As for the performance of DF8SMG, it is natural to say that all of them exceed HK650, of which the main performance such as penetration and stopping effect are more than twice that of HK650.

The price is also not to be said.

The unit price is $12,000 for the Simple Rifle, $13,500 for the Machine Gun, $17,000 for the Sniper, and up to $22,000 for the All-Status.

It is for this reason that at the press conference, D&F emphasized that the DF8SMG is designed for the future, and for the time being, it is aimed at special operations.

In other words, the DF8SMG is not suitable for equipping regular troops.

Of course, for local tyrants who have too much money to run out, that's casual.

Since no prototype guns were made, D&F simply showed renderings of the machine gun firing 12mm countersunk rounds, providing the main performance data.

The price of such a heavy machine gun, for sure, is not cheap.

Of course, not many people pay attention to heavy machine guns, after all, the fist products of the conference are DF6PD and DF8SMG.
