WE-Tech Lower Receiver for SVD Series Airsoft GBB Sniper Rifles

"This is indeed the WE-Tech lower receiver replacement. It does everything the OEM one does except one major thing: this replacement doesn't come with the small metal ball that locks the lever that detaches the upper receiver from the lower receiver. I don't know why this replacement doesn't have this, but it would've been very convenient to have it as I can't find where to buy that small ball. So what I do is I use electrical tape to hold that lever in place. 4 out of 5 stars because it's the OEM replacement but doesn't come with one major component.
