- Base for Attaching Stock Pipes to Picatinny Rear Stock Base!
- Compatible with Various M4 Stock Pipes and Stocks!
 
This Rail Stock Mount Base is designed to be installed on our Picatinny Rear Stock Base series or on firearms like the SIG MCX that are equipped with Picatinny rails at the stock base. It allows you to customize the appearance of your gun by combining it with a variety of M4 retractable stocks, including those made overseas. It securely holds the stock pipe to the gun body, contributing to greater stability in your shooting form. 
 
Notes:
Stocks and stock pipes are not included; please purchase them separately. If you need a stock pipe, consider our "Rail Stock Pipe Adapter Lite."  
 
Depending on the type of stock pipe you use, there may be gaps or play, and some may require modification during installation.  
 
The length of the fixing screw (M5) may vary depending on the stock pipe type. Screws are not included, so please refer to the diagram (screw less than 5mm from the end of the stock pipe) and prepare separately or cut to size if necessary.
