Thanks for summary of problems with your 338 build. Hoping some of your methods help me in addressing mine.

Will post additional pics of internals. Appreciate your responses

I started the build with a smoke composite fixed stock but it didn’t work with relief for my thermal so I switched to the UBR 2. I’ve wondered if the BCG was too light, and I’d be inclined to think that contributes to it not cycling properly but the marring on the cartridges makes me think I’m missing something else…

Thanks for response. I don’t see any evidence that the BC is slamming into the ears. Re the stock depth, I had to add Armaspec spacers behind the spring but, yes, it is contacting the lower.

Thanks for response. I have the UBR 2 with the ARM153-308 spring. Oddly, when I go full gas it won’t cycle. In fact, the ejector seems to get jammed with the cartridge still in the chamber. I have to adjust the gas to roughly 3/4 full for it to eject the cartridge but it still won’t feed the next round. I’m using a magpul pmag so I wouldn’t think it’s the quality of the magazine but I’m considering trying a different one to see if that changes things. I thought about replacing the BCG but the idea of the rifle was to be an ultra-lite 338 so I’m trying to avoid that.

I recently build a 338 federal LR308 and I am struggling with getting it to cycle properly. After a great deal of adjustment to the gas block, it gotten it to fire and eject the cartridge but it will not chamber the next round. There is also significant scratching to the bullet and casing. I’ve taken a dremmel to the feed ramp to polish it but it only slightly lessened the scratches and continues not to feed. The rifle is built on and SLR B-30 receiver set with a Wilson Combat barrel, a JP Enterprises low mass 308 BCG, Superlative Arms adjustable gas block, Geisselle two stage trigger, Radian Raptor charging handle, Magpual UBR Stock with an Armaspec SRS AR10 spring and similarly high end parts. It has the most expensive components of the half dozen rifles that I’ve built and yet it simply will not work properly. I’ve attached a few videos showing what it’s doing. If anyone has some advice I’d appreciate it. IMG_3344.MOV IMG_3343.MOV IMG_3342.MOV
