Nice to read you on firearm forum too Mr. Smith, i really like what you write…
I must tell you that i have a TRG-42 in .338 with the NEAR base. After 2340 round and a NF 5.5 - 22 x56 on top, it NEVER came loose yet… But anyway, time will tell us.
The reason i write too is that Richard at Near produce the BEST muzzle brake for the TRG-42, you notice a cloud of dust in your review and you are right but not with the Near brake, the port just don’t go UNDER the brake A LA Sako, also, a found the Near to be more easy on recoil as there is 4 wall instead of 3 for the sako… Hehe, you should review some Near product… Hope you will have the chance, like me, to feel the difference by yourself…
