I have a the src gen III mk36kv. the only reason i saved the extra money was for the KV stock, which did not disappoint. This is an incredible stock. If you want specs, look at the review below. But when you buy this, if you have a big battery, be prepared for some wire squishing. The plastic coating on my battery wire has been cut through, but i fixed the problem. Still, BUY THIS!!!
