CMMG upper...help

[ninjawho?]

i have a ccmg upper on a NFA lower i havent shot yet....should i get the plug..should i expect some problems??

[onegtalon]

Only way to know is to shoot it first. The kit IS cheap so it wouldn't hurt anyway IMO.

You need to shoot it first... Though, i will say... The kit is worth while IMHO.

Good luck getting this resolved. I have had nothing but problems with my CMMG rifle and even worse luck with their "customer service" staff.

It wasn't always that way. Sorry they are giving you problems. I would help but I'm kinda on the outside now.

The TACCOM Reliability Kit will improve any Atchison type conversion or dedicated bolt.

range report with the Taccom kit in place.

1st off...I thought the firing pin was a bit loose fitting , called the Taccom dealer and asked a few questions , he took the time to explain all to me...sounded good , so off to the range I went...

winchester 36grn....still had a few light strikes , much less then before the kit

federal lightning 40grn....still a few light strikes

cci velocitors.....100% (before the kit it was maybe 50%)

Rem golden 36grn (the 525 bulk packs)....almost 100% with only a few light strikes , out of 300+ rounds I had only 7 light strikes and all but one went bang when tried again..

I have to give the kit a big thumbs up

I ordered the complete kit , and belive it was woth every penny spent ....

thanks to all that refered me to the TACCOM kit , guess now I'll need to stock up on more ammo (the good ol' 525 bulk pack seem to work best)

What's wrong with using a .22LR CMMG upper with a poly lower. I purchased the complete (w/butt stock) lower for $109.00 two months ago, and just found out that CMMG has shipped my left handed Revo upper today (!). Very excited. I thought I would just mate them and be happy with fun, low-cost shooting. Is this not a good/dependable config?
And if the upper is specifically designed for .22lr, is that little insert part useful?
Thx,
B

So long as the upper mates to the poly lower, there shouldn't be a problem.

Another thing to check when having light strikes is the bolt rubbing against the bolt catch. That will slow the bolt down and could keep it from closing completely.
Make sure the bolt is going completely closed or you could have an OBD.

I also suggest buzzing the chamber on the CMMG.
Go to the CMMG YouTube and you will find a video on the procedure.

I stickied this thread there is alot of great information here

I had the same issue, if it's a notched hammer the cmmg will not like it. I also bought the pressure plug. Hopefully that helps

[NorCalDustin]

The Pressure plug goes along way to reducing issues...

Got a CMMG upper and have the TACCOM kit.

The TACCOM parts say disassemble bolt as direct by mfr., but the CMMG documentation says don't disassemble past field strip so I don't have instructions for that.

I don't want to cheese my CMMG parts, anyone got a link to info on how to get it apart to replace/adjust firing pin and replace extractor?

Thanks

[onegtalon]

Its like the AR bolt assm.

Firing pin - pull the retainer pin out from the side and the firing pin comes out along with the spring.

Extractor - you need to put some pressure on the extracor inwards and drive the pin out, then slowly allow the extractor to come out with the spring.

Does anyone know where to find a Nordic upper (sorry I know this is regarding CMMG stuff) I haven't been able to find for some time. If anyone has a Nordic upper 18" I'd be very interested. thanks
