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.

"This eliminated a slight wobble between upper and lower receiver of my WE HK416 GBBR. When tightened, the center piece pushes the upper receiver a bit forward, making the joint point of the rear receiver pin and the lower receiver tight. After installing this, there is absolutely no wobble between the two receiver pieces. There was no negative effect on the operation of the GBB rifle, either. Highly recommended if you are experiencing an annoying wobble with your rifle.
