TTR 700 Family

How does it work? 
    Our patented barrel change system goes back to zero every time with only hand tightening. There are multiple surfaces that all must align perfectly. This insures that the rifle returns to zero.

What do you do to make the TTR-700 accurate?
     With each rifle we begin with truing the action. Next we true the bolt and true the barrel to the action. The factory trigger is reworked or replaced. The fully prepped action is bedded into the stock. This procedure gives constant repeatable performance.

How accurate is the TTR-700?
     These rifles fire ½  MOA  or better at 100 yds.

 

Compak-16 Family

Why change from the Stoner Gas System?
      Since it was adopted the M-16 family has been plagued with a number of problems.
These problems have gotten worse with attempts to improve the system. In particular, when ever the gas port of the Stoner Gas System is moved toward the chamber.
Problems seen with the Stoner Gas System:

1. Failure to Feed
2. Failure to Extract
3. Poor Barrel Life
4. Bolt Fracture
5. Barrel Droop
6. Action Fouling
7. Poor accuracy with wear

 

What did you change with the Compak-16?
     We changed the following:

1. The Gas Trap - Instead of the Stoner Gas System.
2. The Barrel – Heavy contour with Progressive Gain Twist Polygon Rifling.
3. The Gas Tube – Same mil spec but of a different length.
4. A Sling Swivel – Optional
5. A 4 Quadrant Rail System – Optional

How do these changes alter the weapon?
      The Gas Trap changes the time pressure curve of the weapon. That means the weapon has a lower cyclic rate and is more controllable even on full auto.
 
       The Barrel is made of a specialty steel for long life. The heavy contour keeps the barrel stiff for greater accuracy. The PGT Polygon rifling helps resist wear and extend the life of the barrel.

        The Gas Tube has an extended life because the adiabatic cooling of the Gas Trap lowers the operating temperature of the gas tube.

        The Optional Sling Swivel operates ambidextrously when using plastic furniture on the rifle.

        The Optional 4 Quadrant Rail free floats the barrel and allows air circulation for better cooling especially when firing full auto.

How does the sequence of Operation differ between the Compak 16 and the M-4?
        Compak 16

1. Weapon Fires, bullet goes down the bore and exits the barrel (NO GAS PORT).
2. Bullet enters the Gas Trap followed by the products of combustion.
3. Products of combustion expand and undergo adiabatic cooling and the bullet exits the Gas Trap.
4. The Particulate matter in the gas stream solidifies and exits the front of the Gas Trap
5. The remaining (much cleaner) gas goes down the gas tube to unlock, extract, eject and reload the weapon.

             The M-4

1. Weapon Fires, bullet goes down the bore and past the gas port.
2. Gas exits the gas port and goes down the gas tube.
3. Products of combustion go into the action and it begins to unlock, extract, eject and reload the weapon.
4. The bullet leaves the bore of the weapon. 

 

Why is the Compak 16 more reliable?
       There are a number of reasons for this.

1. The Compak 16 stays cleaner since the products of combustion are cooled and go out the front of the Gas Trap. In the M-16 family unburned powder and soot from burned powder is deposited into the action with every shot.
2. When the Unlock, Extract, Eject cycle begins in the Compak 16 the chamber pressure has dropped. In the M-16 family the chamber pressure is still high and the dissimilar metals of the cartridge case and the chamber wall want to adhere to one another (the Blish Effect).
3. The change in the time pressure curve produced by the Gas Trap causes the weapon to cycle closer to the native rate of the mechanism. As you drive the cyclic rate up beyond the native rate of the mechanism it becomes progressively less reliable.
4. Because our barrels will stabilize ALL ammunition ever fielded by the US military having a problem with functioning from that arena is nil.

Why is the Compak 16 more accurate?
      Starting at the bolt, we mate our bolts to our barrel extension. This give a more uniform cartridge head support. The progressive gain twist causes less stress on the jacket/ core junction of the bullet. The barrel is stiffer because of its heavy contour.
The barrel has a target crown that is well protected (inside of the Gas Trap). Since there is NO gas port there is NO engraving of the tail of the bullet by a hot jet of gas as it passes the gas port.(this robs you of some of the accuracy you paid for in every bullet).

How can the Compak 16 fire 3 different wt. bullets?
      Stabilization of bullets depends on the amount of contact of the projectile with the rifling of the bore. With our PGT polygon rifling we chose the system to allow the use of ALL the ammunition types the US military has ever put into the field.

Silencer Purchase

     A private citizen may purchase a suppressor from Arms Tech Ltd. To take possession of the suppressor he or she will have to complete a Form 4 thru a local class 3 dealer. Once the suppressor is paid for we will initiate a transfer of the suppressor to the class 3 dealer of your choice. Expect this to take no less than 30 days.  Once the suppressor is in you class 3 dealer’s possession he will then direct you to fill out the form 4 (which will cost $200.00 for the tax stamp). Dealers usually charge a minimum of $50 for the transfer. Expect approximately 90 days for the Form 4 to go thru.
     Government Agencies, Police Departments and municipalities purchases are done on a Form 5 and do NOT require a tax stamp. It STILL TAKES TIME FOR THE TRANSFER however.
      The following states allow the civilian ownership of suppressors when last researched: AK, AL, AR, CO, CT. FL, GA, ID, IN, KY, LA, ME, MD, MN, MS, MT, ND, NC, NH, NV, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WA,WI, WV, and WY. Please check with your Class 3 dealer for the latest information.
