RA-Tech Steel "Magic" Receiver Pin for WE / WA / G&P M4 Series Airsoft GBB Rifles

"Just received one of these the other day. I have a G/P Troy aeg that I have had for quite a few years. I barely use it but the few times I have taken the upper and lower apart, I realized I was having a slight wobble issue between the upper and lower receiver. I purchased this pin in hopes that it would solve my issue. The head of the pin (D shape ) was slightly too wide. It was hitting the area that the spring and pin sit inside which helps hold the original pin from falling out of the upper. I took my Dremel and sanded down the flat face on the pin a little and I was able to fit the pin. This is still worth every penny, as it solved my issue. Yea the price is a little high, but absolutely worth it.

"This thing is awesome and well-worth the money. Really helped "tighten up" my KWA LM4 RIS.

"I used the magic pin on a classic army M4 AEG which was slightly loose between the upper and lower receiver . This caused feeding issues as the mags didn't sit flush enough up to the hop unit . After the magic pin was fitted it pinched upper and lower receiver together perfectly and eliminated the feeding issues . Fantastic solution to a common problem I would highly recommend this item.
