SRS Upgrade Parts

Shop our roster of upgrades for Silverback's premium bullpup sniper platform, a highly-detailed and officially licensed replica of Desert Tech's very own SRS.

Silverback SRS Upgrades and Spares

The Silverback SRS is a bullpup pull-bolt sniper rifle that packs a long barrel into a compact overall length. It performs well out of the box, but the platform is designed to be tuned, and this collection brings together genuine Silverback parts plus upgrades from other specialist makers.

Hop-up chambers and rubbers

The hop-up is where most players start. Options include MAXX Model precision hop-up chambers, the Maple Leaf "THE LAST" CNC hop-up chamber set, the Silverback SRS/HTI hop-up unit and FAST hop-up unit, a 70 degree hop rubber and nub, and a Maple Leaf CNC nub tensioner. Note that the MAXX Model chambers come in right-hand (R/H) and left-hand (L/H) versions, and for either AEG-type or GBB-type barrels, so choose the version that matches your rifle and barrel.

Pistons, cylinders and spring guides

For the power train you'll find Silverback variable mass pistons and a steel variable mass piston body, the Sniper Mechanics W.A.S.P piston, a twisted stainless steel cylinder, nylon and aluminium spring guides (including a version with a thrust bearing), and steel and open piston sears. Rapax Power UP rings let you adjust power without swapping the spring. Always chrono your rifle after changing internals and stay within your site's limits.

Magazines and pouches

Spare SRS magazines are available in metal and polymer, in a choice of colours, along with replacement flexible followers and a dedicated SRS magazine pouch to carry them.

Stock and external parts

Buttplate spacers (solid and hollow), a buttplate base with rubber recoil damper, a replacement nylon stock, steel/aluminium magazine catch, cylinder pull bolt, a replacement screw set and a 24mm to 14mm adapter help you tailor fit and finish, or replace worn parts.

HPA conversion

If you want to run your SRS on air, the Mancraft SDiK sniper HPA conversion kit is available for various models. You'll also need a tank, regulator and line.

Tips Before You Buy

Check whether your rifle is an SRS A1 or A2, or the HTI, as some parts are model-specific. Pay attention to hand orientation and barrel type on hop-up parts, and if a part is listed for both the SRS and TAC-41, it will fit either platform. If you're not sure, contact us before ordering.
