The newest project

**Gunco** · 09-27-2009, 06:32 PM

I've been collecting parts for my next project for the last few months. The hk91 receiver I've had for a number of years. It had some damage to the front trunnion area and the cocking tube. no worries we can rebuild it.

Just got a G3 barrel and the new trigger group and lower. I have all the parts need now.
Its time to start on the HK51 project...

First question. Which might sound like a newbie question but never having done it....What is the best way to cut and crown a barrel with hand tools?

All the links I'm working with.

Is the trunnion already in the receiver?

Brownells sells the tools to do the job correctly if you want to do it yourself

Here is the low-buck method, basically a carriage bolt + valve lapping compound:

This is a bit more involved with a crowning reamer:

And some other info, i.e. special tools:

You could always send the unmounted barrel to a gunco member with a lathe.

If you're looking to pay someone for the service, there is a guy over on Falfiles who is highly recommended. He shortened a Fal barrel for me, rethreaded the muzzle and recrowned it all for somthing around $35-40. He has done this service for many on Falfiles and does a fantastic job

If you're interested I can dig out his name.
