This machining service provides bore, ream & hone your Fury/6P/C2/M2/C3/M3/U2/Z2/M4 & Weapon Lights to accept 18mm cells. 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. Final inside bore diameter is 18.90mm & will accommodate every current 18650 cell made today. The bore is a continuous cylinder without a forward shoulder - because the shoulder interferes with some long body drop ins. The forward shoulder is available on request if desired.
The smaller tube L1/A2/E-series & Scout Lights 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 larger in diameter than any prior AW cell & may not fit in the E-series ... AW2900/AW3100 are the best choice. Final inside bore diameter is 18.50mm & will fit many but not all 18650 cells - you'll need to sort through your cells for best fit. Cell length is important in L-series light & they require the shortest flat top cells in order to function.

Final boring pass, bar run in reverse to eliminate deflection caused when machining titanium.
Surefire M600 Scout Light® bored for 18mm cell (Please note - Scout Lights use Surefire E-series dimensions & may not work with some oversize cells like some 3400 mAh. Cells up through 3100 mAh are recommended.)
Surefire C2 bored for 18650 + custom machined spacer for CR123 cells to reduce rattle.
Mac's Customs Ti EDC bored for 18mm. The design of Mac's lights is very robust & thick, making them ideal for boring.
NOTE #1: most Surefire machining mods don't require the entire light. Please ship only the parts to be machined, usually just the bare body. Removal of the clip, O-rings, combat rings, etc. is greatly appreciated.
Note #2: The newer X-Series from Surefire have thread locker sealant (glue) at the body to head joint. Their website offers this caution:I can bore the X-Series lights with head attached but it is much more complex & time consuming & cost is 50% more than a normal (head removed) boring job. Full details in post #199.The heads of some SureFire flashlights and WeaponLights are fixed in place and are not meant to be removed. If the head of your illumination tool cannot be unscrewed with moderate hands-only effort, then it is not meant to be removed.
Note #3: My shop primarily provides trouble shooting, emergency repairs & fabrication. Flashlights are machined whenever the time is available & your light may be here for 2-4 weeks (sometimes longer) before machining. 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.
Boring (with head removed)*:
Two cell lights like the Fury P2X/6P/C2/M2/etc are $42 + shipping.*
Three cell lights like the Fury P3X/9P/C3/M3 & any E-Series or L-Series lights are $52 + shipping.*
Four cell lights like the M4 are $62 + shipping.
*Recent X-Series light have required boring with the head attached & cost is 50% more than shown above. The Fury P2X is $63 & the P3X is $78. The Z2 is extraordinarily difficult to set up & machine so the cost is $63.
Spacer to fit CR123 cells:
$10 each or $15 for two to fit a 2-cell light
$15 each or $25 for two to fit a 3-cell light
$20 each or $35 for two to fit a 4-cell light
Weapon Lights require a much longer set up & take more machine time. Pricing is based on how many parts have to be machined since some are 1-cell, some 2-cell & some are 2-cell + extender.
One piece WML's are $63 + shipping.
Two piece WML's are $94 + shipping.
Three piece WML's are $119 + shipping.
Elzetta 2-cell or 3-cell (including the Bravo & Charlie models) are bored from the head end & stoping slightly short of the tail end - please see image in post #242. This is the best way to preserve the unique tail profile & standard rates apply. Please send complete light so I can verify function after machining is done.
SWM V10R Ti, V10R Ti+, M11R Ti, etc. :
Boring the body for either 17mm or 18 mm cells is $84.
Boring the extender for either 17mm or 18mm cells, de-hex extender & diameter match to body - $45.
Other SWM mods are listed under "Mechanical Modding Services"
Custom flashlights: Bare titanium single cell lights like the McGizmo Ti McClickie Pak, Mac's EDC, etc. are $168. Aluminum body single cell lights are $84. Please request a quote if your light has any type of coating (Cerakote, DLC Hardcoat, color anodizing, etc.)
Battery diameter & length vary widely.
AW18650/2900 consistently measure .725"-.726"
AW18650/3100 measure .722"-.723"
Panasonic 18650/3100 button tops are .729"-.730"
Panasonic 18650/3400 run very large, .738"-.740"
Length runs anywhere from 65mm to 70mm (including the positive button if the cell is button top). L-series lights usually need the shortest possible flat top cell. When running 2x18650 you may need to run a button top at the tail end & a flat top at the head end.
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.
LEO-MIL-FF-EMT - please provide proof of status for special pricing (as much as 15% off + 48 hour turn around for duty lights).
