Excellent .22lr Conversion Kit From


Recommended Posts

Just wanted to give some positive feedback on the Blackdog machine .22LR conversion kit I just got from tsmgdrumdr. Merle sent the kit tuesday and I had it installed in my 1928 WH in 5 minutes or less. I used the Blackdog machine stick mags and all performed flawlessly! Took it to the range today and ran 300rds of CCI-Mini mags through it without a HITCH! Ran like a clock and grouped 30 rds inside 2 inches offhand!. Merle went the extra mile to make sure I knew exactly what to do and was extremely gracious with his time. This is a super product and a ton of fun! Cant say enough good things!-Rob

I also got one from Merle when he and I were at TATA. He cut my barrel to leave in the stock extractor and bolt for the raised cocking knob on a 1928.

 

I had some friends over shoot Saturday and we fired 1500 + 22 lr ( 550 Fed bulk pack, 500 CCI blazer, 200 CCI Mini-Mags,( 200 Win Dynapoints , 150 Rem Std Vel with a suppressor ), and some Stingers. WE had " ONE " failure to extract with the Fed Bulk pack . I did run a patch down the barrel every 500 rounds to clean the chamber .

 

Rpm was about 800 with 9 1/4 " spring and 775 with a 10 " spring. These were my heavy duty ( M1 / 28 ) springs that I cut down .

 

I would recommend this kit to anyone thats want to have some cheap fun with a Thompson . Merle says he only had about 10 kits left at this time , and does not know if Black Dog will run any more . My advise is to buy now ! :agree:

Glen,

On the the springs-

I only have used the once that came with the kit and the stronger of the 2 I received worked best but was fast.

 

I have several std. 1928 springs- Do I just measure off 10 inches exactly and snip it?

 

I can cutting it a little at a time and testing would be optimal but I would have to go to the range and do it

 

and I rarely get a chance
