This system can significantly reduce the overall firing sound of a bolt-action airsoft replica, with minimal or no loss in muzzle energy when properly tuned.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThis new version of our airbrake kit replaces the previous three-piece aluminum set with seven finely graduated airbrakes, injection-molded in reinforced polycarbonate, a high-performance engineering plastic known for its durability, resilience, and precision. The polycarbonate construction ensures no compromise in strength, reliability, or performance compared to the former aluminum design.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe seven airbrakes (sizes XXS, XS, S, M, L, XL, XXL) come attached to a single sprue, allowing users to easily select and detach the size that best suits their performance goals. Sizes XXS, M, and XXL correspond to the previous aluminum models, while the four additional sizes allow for much finer adjustment of damping effect, letting players optimize noise reduction without sacrificing power.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eHow to choose your airbrake:\u003cbr\u003eTest your replica with a chronograph using each of the 7 airbrakes. You should get a curve that starts with a stable plateau before dropping off sharply, as shown in this example (see chart below). Choose the longest airbrake that does not reduce the replica’s power — in this example, it’s the 12 mm airbrake.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eCompatibility: – Original SRS piston (SBA-BPS-12 [discontinued] and SBA-BPS-13)\u003cbr\u003e– Original TAC-41 piston (SBA-BPS-30)\u003cbr\u003e– Variable mass piston for SRS (SBA-BPS-18)\u003cbr\u003e– Variable mass piston for TAC-41 (SBA-BPS-31)\u003cbr\u003e– SRS Push piston (SBA-BPS-14, discontinued)\u003cbr\u003e– SRS Push bolt kit (SBA-BBA-17, discontinued)\u003c\/p\u003e\n\u003cp\u003eNot compatible with:\u003cbr\u003e– TAC-41 GBB hop-up unit and cylinder head (SBA-HOP-31 and SBA-CYL-33)\u003cbr\u003e– Early SRS A1 pistons (SBA-BPS-02, SBA-BPS-03, SBA-BPS-04 – all discontinued)\u003c\/p\u003e\n\u003cp\u003eSBA-BPS-19\u003c\/p\u003e","brand":"Silverback","offers":[{"title":"TAC-41\/SRS Piston Cup with Polycarbonate Precision Airbrake Kit (x7)","offer_id":55514000916804,"sku":"SBA-BPS-19","price":14.71,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/3613\/2164\/files\/sba-bps-191s.jpg?v=1755860479","url":"https:\/\/www.skirmshop.nl\/en-de\/products\/tac-41srs-piston-cup-with-polycarbonate-precision","provider":"Skirmshop","version":"1.0","type":"link"}
