Front Frame Lock Pin for M4 Metal Frames:
This frame lock pin prevents looseness in the main frame caused by frequent disassembly and assembly, or frequent use in airsoft games.
It corrects and secures gaps between the upper and lower parts due to individual differences and manufacturing tolerances between metal frames.
Important Notes:
Do not force the pin when replacing, as this may cause damage. Please note that the center of the pin may not line up with the center of the hole on the frame when securely fastened.
If assembly is difficult, disassemble the product and attach each piece to its respective frame before reassembling.
Please note that some imported frames may not fit this product, or there may be a large gap, resulting in looseness. Please be careful not to overtighten the screws, as this may cause damage.
