A-Tec CMM4 Alu Mod

[2428 miles]

To those of you that took the plunge and bought one of theses Aluminium CMM4’s

1. How are you getting on with it now a few months have passed?

2. Is the gas cutting an issue or is it just hype?

Thanks in advance!

Loving mine - no signs of any wear yet and have it apart regularly because (a) the concern above and (b) it's so easy to dismantle and clean

"doesnt look out of place on the wonderfull BLASER "

Is that because you have a problem keeping it on it Pete?

I liked the noise reduction and weight balance of my CMM4 but found it cut badly and I put less than 100 rounds through it. I also did not realise before I bought it that it stated in the instructions not to use bullets of 100gr or more and not to use plastic tipped bullets in it. I was using a .243 and the moderator was marked to be used up to 6.5mm and at that size you would be expecting to use bullets heavier than this.

I have sold it and since ordered the new atec maxim with steel baffles and aluminium body.

It weighs more I believe about 370g for the 4 baffle version but is cheaper than the cmm4 was.

It's arriving on Friday so looking forward to testing it out.

Works ok on mr .17 fireball but it is gas cut badly.

David, You will not be disappointed.
I got mine last week and so far have zeroed with it on my new .243 barrel, three rounds, zeroed with it on my 30-06, five rounds and shot a fox and a Fallow.
Played around with it on, using some reloaded heavy bullets, light bullets, PPU light bullets and some PPU heavy bullets all in all had some fun and put a few rounds through it.
So far no sign of gas cutting, easy to clean and balances on my Blaser wonderfully

Just to throw a spanner in the works, I have the Roedale V with the first two baffles in stainless steel coated in TAiN. Now I have learnt to tighten it up properly it works a treat. 100 rounds, no cutting!

Chuffed to bits with mine so far. At first I noticed some erosion (roughening) on 2 of the baffles, but this now seems to have stopped. I use mine on a 308 and a 243, and it seems very efficient on both rifles.

i have a 30cal cmm4 will not come apart anymore gas cutting on the baffles is bad, this mod is 9 months old and used on a 270 and had about 200 rounds through it and as started getting louder i use it when stalking and checking zero i do not sit on a range putting round after round through it i have contacted jackson rifles and the reply i got was they are not meant to be taken part to be cleaned and the baffles are meant to wear like this it is a throw away part and the baffles are replaceable at a cost of 18 each as and when u need them and if it will not come apart just send it to them and they will send me new baffle sections at my cost so much for customer service , so if you want a mod which will last more then a few yrs stay clear of the cmm4 , and i still have the emails from jacksons telling me this.

wow! never expected the cutting to be so pronounced.
have to ask yourself where all that material is going!?

I haven't had much luck with Jackson rifle's either

 

[User00004]

I use mine on a 22-250, I have put about 200 rounds through it, no visable wear, still very happy with it, would get another if needed to.

As for £18 per baffle, I wonder how much the end and threadded end are?

18x4= 72
Surely the threadded end and end section don't cost circa £170 to buy......Might just look into that.

It seems to me that the only negative to the A-Tec Cmm4 is the gas cutting on the baffles.

Does the Roedale Delta suffer the same fate…?

I cant make up my mind between the two!

As per my post earlier, I have the Roedale V with the first two baffles in coated stainless. it has had 100 rounds through it so far with no sign of cutting. I am on the Gloucs/Worcs border if you want to see one.

Hi Pete
When you say it keeps balance of the rifle perfect i suppose the balance point is about 53 metres down range

I had a look at a mates the other week and his was suffering from cutting too. I went for the CMM6, all good so far but it don;t half get hot!

Perhaps the Roedale with 2 steel baffles is the best comprimise....

Can you buy mods through the post?
