A Tec CTM-4 V Maxim

BWH

Well-Known Member
Any one any experience of the CTM 4 Mod? I am wondering if it might suit me better than the Maxim that I have because it is slightly narrower as is the CMM4, and might not interfere as much with the sight picture throught the scope. I prefer the reflex style over the muzzle mounted design hence the CTM rather than the CMM. Thanks
 
What calibre are you planning on using the mod on BWH ? I ask because I've found that with big calls 30/06,270 and certainly all of the magnum calibres theres no substitute for either large diameter reflex types or the longer muzzle mounted cans.Having said that I've been impressed with a calibre specific Hardy Gen 4 mod that although isn't the quietest is probably one of the best all round compromise mods I've tried (but make sure its calibre specific)
Another point is that I don't think Jacksons are importing the CTM into the country unless its by request
 
I have one on my 243 - 270 - 308 very pleased with them no weight and does what i want it to !
I truly cant understand people putting great big bulky heavy mods on a stalking rifle A Tec cmm4 all the time for me
 
It is for a .25-06. I have finally got all the components together for this rife, the last part of which was the Scope. It was only on mounting it that I found the issue with the moderator interfering with the image. It is not the end of the world, but I would prefer to minimise it if I can. I would also quite like to reduce the weight of the mod. The Maxim seems good in general, but I could get away without the steel inserts I think. I dont suppose it would be an issue for Jackson Rifles to bring in a model that they dont stock routinely. Thanks for the input.
 
I have CMM's on my 22-250 and .270, the 22-250 is a dream to shoot, noise supression is fantastic.

The one on my .270 is again cracking, you still get a recoil from it that certinally causes me to lose sight picture. I wouldn't change either though unless someone showed me a lighter moderator that was as good and cost the same.

When I need to replace either it will be with the same.

Do you find that the CMM is a problem with lamping and light reflecting? Or with the mod in the sight picture?
 
I run a CMM4 on my .270 and have found it excellent - due to its minimal weight, I take freehand shots quite confidently now, whereas the previous mod' made the rifle impossible to shoot off hand. I had a few worries about gas cutting on the first and second baffles, as a mate had problems with his on the same calibre, but having just dismantled it for a look, it's still in really good nick despite having had at least 400 rounds through it. It isn't as quiet as the big can I had before but the difference is negligible and recoil reduction is just as efficient.

Thanks all. The main reason for changing is the issue with the Maxim affecting the sight picture and although I havent tried it yet I am sure it will be a problem with the lamp. The CMM 4 is a little less diameter so I am hoping this will be enough to stop interference with the low mounted scope picture.
 
To get rid of light flash back from the moderator (or front sight if fitted to rifle) you could mount the lamp under the rifle. Not easy to do but it certainly gets rid of the problem. This lamp position also stops the flare back from mist / humidity in the air from the beam of light because you're not looking through the beam like you do if the light is top mounted.
My old bunny rifle had a front sight ramp that flashed back in the light - I stuck a bit of wooly velcro on it & that helped. You could experiment with something dull & non reflective stuck to the back of the mod.
Also a higher scope mount & stock comb is possibly another way round your problems.

Try putting some black insulating tape across the bottom third of the scope lense. You will not see this as you look through in the dark. It stops the flare off the mod from entering the scope, and in the day just pull it off. Also try using more mag on your scope, this will close up your field of view, and stop the problem of seeing the mod. Hope this helps. BTW I was interested in the CMM4 and it looks like you guys rate them, so may give one a go for when testing loads or high seating. Otherwise I have gone right off mods as they make such a negative difference to the handling of a nice gun. I find on my 22-250 that if I drop below 9X mag I begin to see the mod.

Also try using less magnification on your scope, this will open up your field of view, let your scope gather more light and stop the problem of seeing the mod. Hope this helps.

The CMM4 weighs 240 grammes and really makes very little difference to the handling of the rifle - I don't notice any barrel dip when it's on and it doesn't alter the swing for running shots. The other nice thing about it is that is doesn't mess with the balance of the rifle when it's slung on your shoulder; my old one used to drive me mad because it added nearly 800 grammes or 2lb to the barrel and caused the rifle to rotate on my shoulder so that the barrel pointed backwards if I didn't keep a hand on it.
 
Oddly I have the MAXIM too and even though my scope is mounted low (a couple mil off the barrel) I can't see it even at 12 power. I have a 4-12 scope. Unlike wood master I would have said that using less mag and a wider field of view would show more of the mod not less! I can only assume that the OP has a higher than 12 mag scope or that his scope has a wider field of view, or a shorter barrel I suppose....
 
one other thought on the Maxim is that its not that quiet.....

All I want is something that doesn't cause permanent hearing damage an its fine for that, but its not as quiet as some out there. mine has 4 baffles, I could buy more as they are available separately, I had considered buying 2 more for range work as I shoot at home and have neighbours about 200yds away but for stalking 4 are ok.
 
I find the CMM4 excellent on 270 and 22.250 - for reasons stated above on (lack of) weight v. sound suppression balance. I have sleeved mine with neoprene and this has taken away what little glare there was under a lamp. I see a shadow of it under 4x mag, but it doesn't affect sight picture as I know many can.
 
I had problems with glare off the mod on a North Star on my fox rifle and solved it with a neoprene sleeve pulled back so it overhung about an inch back. I also tried a maxim on a new rifle but sent it back as it was far too loud, settled on a jetz compact in the end and very pleased with it, moved onto 1 rifle for everything now (had a cmm4 on the old stalking rifle) and it seems to do it all.
