You can run it without an airbrake, with a mid brake or with a full airbrake. Thanks to the guide ring and cup design, even a weighted, unbraked setup at 4.5 joules stays reasonably quiet.

Beyond a certain power, the spring and piston override the brake and slow the air too much, costing power. Where that point is depends on your setup.\u003c\/li\u003e\n\u003cli\u003eIt works with most 13mm springs, although some lower-power SBA springs are a different spec and may bind.\u003c\/li\u003e\n\u003cli\u003eLubricate the cup before use. \u003ca href=\"\/products\/abbey-silicone-gun-oil-35-dropper-bottle\"\u003eSilicone oil\u003c\/a\u003e works best.\u003c\/li\u003e\n\u003cli\u003eBecause of the rear guide design, you may need to lower your sear height so the sear can slide over and release.
