Umbrella SR-25 Platinum DMR

Trigger Type

4-6 Weeks Build Time

Umbrella has a certain obsession with SR-25s. Many of our earliest personal guns involved SR-25s. Besides being unique in a sea of AR15 style platforms. SR25s by design offer a unique gearbox frame which allows for additional air volume. Not all SR25s in airsoft uses this unique feature however. So finding a company willing to take advantage of the longer cylinder while having great externals doesn't come up often.

We're happy to showcase our upgraded CYMA SR-25. Designed for DMR use, and will fit the DMR role for many fields requiring at least a ""7.62/308" platform to play using the higher FPS.

This gun is intended to use heavier weight BBs, we strongly suggest at least 0.40g for guns shooting 500FPS.

Rene Guzman Fito
Bad compression 1.6 joules max

It stuns me how in the world a company with this reputation and these prices sells something so faulty to the point that im never ordering anything from here again.

I specifically ordered my sr25 to shoot 1.85 joules with .45g bbs and what i got was a disaster, if i apply 0 hop then i get my desired power, but the moment i start applying hop the joules go down and it can barely even lift the 45s. This is unnaceptable and i refuse to send the gun back to have inspected since its extra work that i shouldnt have to do, theres a warranty period and all but thats for when the gun starts failing enphasis on "starts" all this has caused is for me to throw their warranty on the trash and just focus on building it myself as i just found i tend to do a better job at upgrading guns than them

Hi Rene, we apologize for the issue you are experiencing with your Umbrella SR-25 Platinum DMR. We understand your frustration and want to assure you that the problem is not with bad compression. The gun is shooting as intended with the rating clocked with 0.20g as per most chronograph rules (Hop off, as hop-on is a common cheat to bypass chronograph rules). However, due to the long inner barrel and the use of 0.45g bbs, the gun may be considered 'Undervolumed.' This can actually result in more accuracy, though it may not exhibit joule creep like an 'overvolumed' guns would. We would be more than happy to swap the spring to raise the power, or we can send you the spring, additional spacers, and guide you through the process over the phone. It is a simple process that only requires removing two screws to replace the spring guide and spring. Please feel free to email us and let us know how we can assist in resolving this situation. We value your business and want to ensure your satisfaction. Thank you for bringing this to our attention.
