How to Install the Chen SI "Shooter Installed" Magwell

Congratulations! If you're reading this, you are the proud new owner of a Chen SI "Shooter Installed" Magwell. If you don't have any gunsmithing experience, don't worry. It's so easy that even an 11 year old can do it (seriously, we've checked).

If you prefer a video tutorial, check out our YouTube video here. If you prefer written instructions, keep reading.

RECOMMENDED TOOLS

- small hammer

- 3/32 punch

- 1/16 punch

- bench block (optional)

- eye protection

- peanut m&m's (included in order)

(We've installed an SI Magwell at a safety table without any of the aforementioned tools. We recommend them, but they are not required.)

INSTRUCTIONS

1. Disassemble pistol and remove your existing mainspring housing. If you have never done this before, there are plenty of videos with detailed instruction on how to do so. Please wear eye protection. *** 

2. Remove all internals from your existing mainspring housing. 

3. Install the MSH internals you removed from your MSH into the Chen SI Magwell 

4. Install Chen SI magwell into pistol, and secure with MSH pin from your pistol. 

5. Reassemble pistol in normal manner

6. Eat your peanut m&m's. :)
