FN® FS2000 "K&M Lightening"

Trigger job / fix for the FN® FS2000

SPEC:

The Lightning was developed from a stock trigger pull that averaged 9lb. 1oz over 10 pulls with a digital Lyman gauge. This trigger fix is the lightest on the market to date at an average of 5lb 1oz. I have gotten it to go even lower but it currently is not reliable to go lower than the 5lb range.

You need to send me your hammer pack to do a bit of machine work on it and do my magic. It is not like the other modifications that I do to lighten the trigger as this one is not a DIY fix. I wish it was but its not.

Instructions for sending in you hammer pack.

1. Remove the hammer pack and send it to my mailing address.

K&M Aerospace - 24206 S 124th st, chandler, AZ 85249

2. Include in the package name and return address. If paying by USPS money order send the MO in the box with the hammer pack.

3. Once the item is sent if you paid with a USPS money order then you need to send me an email with the return address and let me know it is on the way. This way I will have your email address and I can sent the tracking number to you when it ships back.

4. I will be doing this work once a week on Friday and shipping back out on Monday. So if I do not have it by Thursday close of business it will have to wait until the next batch the next week. I will do the work on your hammer pack and you will get yours back. So if yours has issues before it gets to me then it will still have issues when it come back.
