Working on my double dovetail MKI

**cal50** · 04-02-2021 10:57 PM

Finally getting some play time and work done on my Bren double dovetail MK1. I opted to grab a BRP center section which cuts down the built time ( for me) quite a bit. Cut the gas cylinder section to length and milled both the center section and cylinder and welded them together.

Rear receiver heel was cut a little wide and thru the take down hole. Its welded and needs cosmetic clean up but I focused on the internal section.
The bolt and carrier do the "tilt test" and travel freely by its own weight. I built my DPM and RPD the same and they run super smooth.

A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered. Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping. In the USA shipping is $5.00 for media mail. I will accept PayPal, Zelle, MO and good old checks (and cash if you want to stop by for a tour!). CLICK BANNER to send me a PM for International pricing and shipping.

Test fire day tomorrow !

I wrapped up making my "Lime" flavored striker group per print.
Striker is made from 4140 heat treated to 50Rc C , guide rod is 0-1 and tubes are stainless steel.

My MKI was a partial parts set missing a lot of small items and the farther I got the more parts I found out were missing but I think I got all of them now.

When I put firing group together and racked the slide and dry fired it I really thought the striker was weak and not going to snap a primer. To make sure I pulled a Wolf .303 round and chambered it and gave the wife and grand kid in the other room a heads up. It want "BANG" with a nice primer strike.
I had a big smile and they looked confused / condition normal.

The impact force and spring rate is deceiving and will find out tomorrow if it cycles.
Turkey day is coming up and I need to vacate my favorite work spot.

Pile of striker parts~

Test fired primer hit , very robust~

If it runs then I make it pretty~
