This machining service provides bore, ream & hone your 6P/C2/M2/C3/M3/U2/Kroma/M4 (and most other models) to accept the AW18650 or similar diameter 18mm cell. Your light body is first bored to near net size (three to six boring passes), reamed twice to assure dead on straightness & triple honed for final finish. Honing is first done with 320 grit, then 600 grit & finished at 1200 grit. The final ball hone operation leaves a super smooth finish but it is not a mirror finish - for that you'll want to polish the bore with a metal polish like Flitz or Semichrome applied on a snug fitting paper towel.
The smaller tube L1/A2/E-series can be bored for either a 17mm protected cell or for a standard size 18mm cell (like the AW2900 mAh or AW3100 mAh). There's no excess of material to work with so the small tube lights are minimum bored, meaning that the cell will just slip into the bore. The newer AW3400 mAh cells are slightly larger in diameter than any prior AW cell & cannot be used in the E-series.

NOTE #1: most machining mods don't require the entire light. Please ship only the parts to be machined. Removal of the clip, O-rings, combat rings, etc. is greatly appreciated.
NOTE #2: all standard machining mods are listed in this post. I'll be happy to look at any idea you have & quote a price. Please understand that custom mods often cost much more than standard mods.
Note #3: My shop primarily provides trouble shooting, emergency repairs & fabrication to local area business owners. Flashlights are machined whenever the time is available, meaning that your light may not be machined for many weeks after arrival - some lights may wait here for 60 to 90 days before they can be machined. Please don't send your light if you need it back by a date certain. Lights are machined in the order in which they arrive.
Two cell lights like the 6P/C2/M2/Z2/A2/E2 and small one cell lights like the L1/3P/E1 bored to 17mm are $42 + shipping. This includes the U2/Kroma basic service, please see below.
Three cell lights like the 9P/C3/M3 are $50 + shipping. Also the E-series & L-series lights bored to 18mm.
Four cell lights, like the M4, are $59 + shipping. Boring a U2/Kroma for rear battery loading is also $56.
SF A19 extender is $12 when bored with a light or $22 if bored by itself.
LEO-MIL-FF-EMT - please provide proof of status for special pricing.

Battery sizes vary widely. AW18650/2900 consistently measure .725"-.726" (18.4mm). AW18650/3100 measure .722"-.723" (18.3mm). Panasonic 18650/3100 button tops are .729"-.730" (18.55mm). Panasonic 18650/3400 run very large, .738"-.740" (18.8mm). Please keep this in mind when having your E-series bored for 18650. Those bores finish out at 18.5mm & I cannot go any larger than that.
PAYMENT is not due until the work is completed. An invoice will be sent as soon as your work is done. PayPal payments are accepted in USD only. You may prefer to send a check or money order with you light & that is perfectly fine. You may also pay using Visa-Mastercard-Discover-American Express.
