FSE hammer: problem w/ older version?

[Richard W.]

I received an FSE hammer, trigger, and sear set for metric rifles yesterday.

Both the sear and the trigger were marked "M3", but the hammer was "M02".

Should all my parts be the same series? I heard there's now an M3 hammer on the market. Is this a problem?

Richard,

If these pieces were packaged together, everything is fine. I had run about 100 hammers which were marked "M 02" but were manufactured to the "M3" specifications. I decided to change the hammer # in order to have uniformity among the h/t/s.

The only difference between the "M3" spec hammers and the older "M 02" hammers (not yours) is that the sear engagement notch is now gauged with an optical comparator. The depth is .0027" +- .001" Older hammers may have been as shallow as .022"

Your set, as you described having received, is fine. If you should have any problems, I can be reached at hshinn@mindspring.com

Best regards,

Harold/FSE

Sorry about the typo

it should read .027" instead of .0027"

Harold-
Yes, the 3 pieces were packaged together in a segmented clear plastic sleeve (from TAPCO).

You have put my mind at ease. Thanks very much.

Glad to see that you are posting. I sent you an email regarding the status of the exchange of my .429 gas piston for the .431 piston. I sent it to you late July / early August, but have not heard back.

Please give an update.

Thanks!
