Finnbear, the nice thing about the Delta is that one could order a moderator made for purpose.
I have three on my rifles at the moment.
A stainless 5 baffle bead blasted on my 223. This one would also take up 6.5-284, ultra sturdy. Weight 480 grams.
On my main deer rifle a sako 308 I have an all aluminium 5 baffle mod. This was a early test example and weighs 175 grams!!!!
Absolute fantastic handling rifle with this mod on. The newer Aluminium mods weigh a bit under 200 grams. I have shot about
80 rounds through that mod and checked the first baffle this afternoon, no wear. I presume it will take a few years before
the wear on the aluminium baffles could maybe become an issue, but then one can buy single baffles to replace.
On my 243 light stalking doe rifle, i have a "Light" delta 5 which is all aluminium except the first two baffles which are in stainless.
This compromise moderator weighs 280 grams.
All components can be exchanged. Only thing one must watch out for is that one doesn't use small holed baffles on a large cal rifle.
Delta have only two main sizes, up to 6.5mm and up to 9.3mm. Roedale have made some "specials" for up to 458 win mag.
Of all moderators I think the Delta range is the most flexible and ultra reliable, no messing with delrin rings and if one buys a new
rifle with a different thread one can order a new rear end with the new thread.
The all steel parkerised mods start at 260 Euro as far as i remember.
Top, "Light" 280 grams, mid "Ultralight" ~ 200grams, bottom Stainless bead blasted 480 grams.
Size comparison to the older A-tec moderator.
