LARGE VOLUME, EXTREME PERFORMANCE SUPPRESSOR FOR 45CAL SUBSONIC CENTREFIRE SMALL ARMS
The A-TEC A-SUB 5 was designed with the .45-70 in mind. Large volume and adaptable, it is ideal for employment on heavy hitting 45cal cartridges.
Intended Use
Short barrelled firearms running 45 calibre ammunition such as 45-70. Large diameter for maximum performance and modular to reduce length if desired.
Design Features
- Stainless steel thread boss. First stage steel muzzle brake eliminates excessive baffle erosion.
- Surprisingly lightweight for its large size. Aluminium baffle construction.
- Able to reduce length by removing baffle modules.
- Removing a module reduces noise reduction effect by 2-3 dB.
- Aluminium finished in mil-spec anodising to handle wear & tear over it's life.
- 49mm diameter to maximise noise reduction.
- Muzzle forward, not reflex.
-
Optional A-Lock thread adaptor system. Any thread is supported.
- See link below to add an A-Lock to your order, it is not included.
- The A-Lock can be affixed to your rifle muzzle allowing quick attach/detach of the suppressor. It also provides the ability to use the same suppressor across multiple rifles all with different threads (an A-Lock for each muzzle is required for this and with calibres up to that of the suppressor).
- The A-Lock can instead be locked into the suppressor and the unit attached and detached like legacy suppressors (we prefer to do this for you by special request to ensure it is correct before use).
-
Optional Special order direct thread options.
- Important note on reduction performance: Unique to A-Tec, our suppressors are tested to the latest MIL-STD-1474D military standard which is the most stringent and difficult standard to test to. Research shows our competitors do not test to this standard. For comparing to competitors products we prefer to let our reputation do the talking but you will observe our suppressors performing 5-10% better for a stated dB and significantly better for dB reduction vs. weight & length.
- A-Tec have only one grade of precision: Match Grade. A-Tec suppressors are second to none for concentricity, straightness and fine dimensional tolerances. This is especially evident in our bore apertures which are tight to the projectile to maximise sound reductive effect. To get peak performance from an A-Tec suppressor, one's rifle muzzle must be correctly crowned, threaded and shouldered.

A-Lock Adaptor detailed design
It's a revolution in how you think about attaching your suppressor.
This unit can be used in two ways:
-
Adaptor locked on to the muzzle thread
- This allows the Optima and H2 suppressor to be quick attached and detached in a second with a forceful 1/4 turn.
- This allows a single suppressor to be shared amongst multiple rifles all with different threads. In this case the calibre of the suppressor must be equal or greater than the largest calibre rifle.
- This means the adaptor is on the end of the muzzle, maybe affecting it's aesthetic if it is a thin barrel
-
Adaptor locked inside the suppressor
- This allows the suppressor to be attached using muzzle threads like legacy suppressors.
- When the suppressor is removed, nothing is left on the barrel.
- We prefer to do this for you to ensure quality.
