Silverback Airsoft
Silverback Airsoft, Desert Tech licensed replica, DTSS muzzle brake timing
updated
A big thanks to everyone involved in the SRS success, nothing is possible without your trust and support.
Thanks to all SRS users, to our licensor Desert Tech and to Popular Airsoft.
Since its release in 2015, we have developed and produced magazines, barrels, silencers, suppressors, handguards... as well as many spare parts to customize and fine tune your SRS.
Over the years, the SRS has evolved significantly, but we are beginning to be short of new ideas.
What would you wish to be developed? Your help would be greatly appreciated!

We recommend to use the MDRX replica with 11.1 V battery. In this case, it is not necessary to install the jumper (*).
If you use 7.4 V battery, you need to install the jumper as shown on the video.
(*): If your battery is old, if the temperature is cold, or if you use powerful spring, you may need to install the jumper as shown on the video.

It’s mounted on the lateral MLOK slots with 2 Nylon lugs. A rubber pad pushed by a grub screw will help you to adjust the vertical alignment (canceling the free float effect, we suggest mounting the bipod on the tripod mount if you are using this accessory). CNC aviation grade aluminium construction, 48 grams (hardware excluded).
This rail will give you 95 mm of picatinny rail aligned with the receiver rail, and 2 Mlok slots at 45° angle (1 on each side). It will help you to fix any accessories at the front of your scope, typically light amplification for night shooting or scope cam.

SBA-HOP-31, "GBB" hopup unit for TAC-41 (LINK) include:
- T41-0226 hopup body “GBB” (aviation grade CNC construction)
- T41-0227 hopup rubber socket (aviation grade CNC construction)
- T41-0228 barrel clip (SS304 laser cut)
- T41-0202 hopup wheel
- T41-0203 concave nub
- T41-0224 feeder
- T41-0225 feeder spring guide
- T41-1008 spring
- HOP-316001 60° flat hopup rubber, “GBB” type
- M5X6 ISO7380-2 screw
- M3X6 ISO7462 screws (x3)
- M4X8 DIN7991 screw
- M4X5 ISO4027 screws (x2)
- oring 8×2 (x1)
- 4 mm ball plunger
This TDC (Top Dead Center) hopup has 0.75 mm nub travel amplitude, divided in 50 positions (15 µm per clic). It includes a feeding system to avoid double feed, a 60° flat “GBB” hopup rubber (SBA-HOP-41), and it is compatible with “GBB” hopup rubbers and “GBB” inner barrels. To accommodate different brand of barrel, it can be assembled either with the barrel clip, or with the 3 M3X6 screws.
Because of a different inner barrel position inside the hopup, this unit require inner barrels at least 3 mm shorter than the “AEG” hopup unit equipped with the same outer barrel to avoid inner barrel sitting out of the outer barrel.
- “510” outer barrel requires a 507 mm GBB inner barrel
- “420” outer barrel requires a 417 mm GBB inner barrel
- “330” outer barrel requires a 327 mm GBB inner barrel
This hopup unit is compatible with the advance hopup kit (SBA-HOP-34)

- “GBB” type hopup for TAC-41 (SBA-HOP-31) silverback-airsoft.com/hop-31
This kit include:
- T41-0240, Fine tuning wheel (aviation grade CNC construction with laser marking)
- T41-0241, reinforced feeder (stainless steel CNC construction)
- T41-0242, low nub (stainless steel CNC construction)
- T41-0243, high nub (stainless steel CNC construction)
The fine-tuning wheel is dedicated for players looking for finer hopup adjustment. It has a 500 µm amplitude, with 50 increments of 10 µm (while the original wheel has 15 µm increments). Used with the low nub, you can adjust your rubber pressure from 0 to 500 µm, and with the high nub, you can adjust your rubber pressure from 250 to 750 µm. The laser marking on the wheel help to return to the exact same “click”.
The reinforced feeder will increase the feeder lifetime (but may leave some marks on the nozzle without affecting the normal operation of the parts).

The video explain with a 3D animation the feeding and the hopup mechanism. A dedicated part is avoiding any double feed, or any bbs jumping into the outer barrel. The hopup is a TDC design, fully low profile (the hopup wheel is tangent with the top of the barrel, no interference with the scope). The hopup wheel has 50 position, ranging from 0 mm up to 0.75 mm of preload (15 µm increments / click).

These Carbon barrel extensions are designed to be used directly on our 24mm threaded outer barrels: SRS G-Spec barrels (A1 & A2) and SRS Sport barrels (16’’ & 20’’). To use these extensions on any other barrels, you will have to use a DT muzzle brake (please check references SBA-FHD-06 silverback-airsoft.com/product/srs-30-muzzle-brake-model-a2 & SBA-FHD-07 silverback-airsoft.com/product/srs-338-muzzle-brake-model-a2-dtss-silencer-compatible), and a set of timing shims (please check reference SBA-SIL-06 silverback-airsoft.com/product/fine-tuning-shim-set-for-muzzle-brake/). To properly time the muzzle brake, please refer this video : youtube.com/watch?v=829ujuwRL6Q&t .
You can skip the timing procedure if (and only if) you screw the muzzle brake all the way onto the outer barrel thread, ending in an unrealistic position.
2) Inner barrel length
Please refer to the chart (silverback-airsoft.com/pdf/CBX_user_manual.pdf) to know the maximum inner barrel length of your personal configuration. For concentricity reasons, we suggest you also to respect a minimum inner barrel length (100 mm shorter than the maximum length). Your carbon barrel extension is delivered with barrel spacer(s) (1 piece for the XS model, 2 pieces for S/M/L models, and 3 pieces for the XL model). Install a barrel spacer at the inner barrel muzzle extremity, and if necessary, distribute the others on the protruding inner barrel. Additional barrel spacers can be purchased separately (please check reference SBA-BBS-11).
3) Muzzle-Handguard offset
Please refer the chart to know the distance between the carbon barrel extension muzzle and the front face of the handguard. If the distance is negative, that means the carbon barrel extension muzzle will sit inside the handguard.
4) Integral silencer use
It is possible to use your carbon barrel extension as integrally suppressed barrel by using up to 100 mm (suggested) of foam filling on the muzzle side of your carbon barrel extension. Please check the reference SBA-SIL-18 for additional information.

Fresh from the “drawing board”, here is the concept of our future spring bolt action rifle platform, the TAC 41.
The initial idea is very simple: transpose the mechanism of our SRS replica into a non-bullpup rifle. The cylinder bore and piston stroke are the same as the SRS, with 41cc air volume, hence the name of the project.
Some specs:
- SRS piston fitted with a specific piston end.
- Stainless steel cylinder.
- Stainless steel spring guide with thrust bearing.
- Carbon steel bolt handle with ergonomic bolt knob (M8x1.25 threaded bolt handle, compatible with our full range of bolt knobs).
- APS 13 mm springs. It is possible to change the spring using only the tools included in the stock. To ensure a smooth cocking movement, the bolt is guided in the receiver by POM rings.
- Rigid receiver/outer barrel assembly, using a clamping system similar to the SRS, allowing quick barrel change preserving hop up setting.
- Inner barrel, 510 mm long, 6.05 mm bore, brass material, AEG type, 3 barrel spacers for stability. Outer barrel thread is M24x1 (direct compatibility with DTSS silencers replicas).
- CNC TDC hop-up unit, 50 position, secured by a ball-plunger. It is adjustable while having the target in the scope and the finger on the trigger.
- Trigger box in stamped stainless steel, CNC stainless steel piston sear, mounted on ball bearings to limit trigger pull weight, adjustable trigger pre-load and dual-stage course.
- Carbon steel safety.
- Fully ambidextrous design, conversion can be done within minutes without any optional parts.
- CNC aeronautical grade receiver and outer barrel.
- Nylon stock, fiberglass reinforced, 5 MLOK slots on each side, 2 MLOK slots under, 4 QD attachment points, tripod mount, adjustable cheek rest height, adjustable length with 10mm extensions (3 pieces will be included with the rifle).
- 48 rounds polymer magazine.
- Estimated mass: 2.65 Kg (with magazine and 3 stock extensions), length: 110 cm.
- Release date and price range to be confirmed.
TAC-41 is now in prototyping stage, actual shooting video will come as soon as possible.
