Broke after first range trip. - Armaspec AR10 Gen4 Stealth Recoil Spring

Functionally speaking, for what it's supposed to do, the noise reduction while hand charging is minimal but noticable. Can't say much for function while firing as the plastic base to the spring broke in half after the first few rounds. The plastic shard then interfered with the springs ability to compress while bouncing around inside the buffer tube and caused malfunctions and rendered my rifle unusable until I could get home and remove the unit and pieces. Why this base disk is made of such a brittle plastic is beyond me but is a very obvious failure point that seemingly doesn't stand up to even standard use. It could be I somehow received a lemon, but no response from customer service on armaspecs side asking for an exchange so I'll be returning it and sticking with a JP or standard set up.
