Soon to be available a true custom fit breech plug for all knight bolt action rifles. No more shims, No more headspace issues, No more stuck cleaning patches on 45 cal and No more vent liners to replace.
I have been working with many very experienced knight bolt owners and have what we feel is a great design.
The new plug will be produced by Lehigh Defense which produces a total quality product. It will be made from17-4 stainless steel and heat treated plug will also utilize a tungsten carbide .031 bushing that will last well over 1,000 shots and beyond ..
Bushing is easily replaceable if ever needed .
Production run of breech plug will be made with overall length in excess of installed length.
Rifle owner will need to supply me with breech plug face sealing surface to primer face sealing surface dimension. To obtain proper primer crush (headspace).
Step 1:
Choose your preferred primer and measure primer length with dial caliper. Example .299
Step2:
Install primer in existing breech plug and measure overall length from breech face to primer battery cup surface . Example 1.889
Step3:
Install breech plug in gun with same test primer . (Please remove firing pin assembly from bolt body for this step) next install bolt handle and close bolt completely.
Remove primer and measure primer length if primer is crushed by more than .002 example.297
You have the 3 dimensions in steps 1-2-3 to have your custom fit breech made and delivered .
If not proceed to step4.
Step 4:
Put primer back in bolt and take a feeler guage and place .002 feeler between rear of bolt and action where bolt handle contacts action when closed to headspace primer .
continue this process increasing feeler guage until you obtain.002 primer crush.
So now you will have possibly 4 measurements.
Example
step1 = .299
step2 = 1.889
step3 = .297 Done if .299 step 4
step4 = .005 feeler guage installed you obtain primer crush measurement .297
Done ready to order your custom fit knight bolt rifle breech plug.
Plug will sell for $80 shipped to your door and should be available in 6-8 weeks possibly soon depending on production schedule .
If prefer you can fit plug yourself for $70 or send rifle to me for breech install for $125 which will include breech plug , installation and return shipping.
Thanks,
