For the first time yesterday, I converted an 80% lower to a 100% lower completely on my own (picture). The owner of the mill had an emergency right after we completed his lower, so I had to figure it out.
I learned a couple things that might help you. I was converting a KE Arms 7075 anodized lower using the jig they sell.
- 7075 produces little razor shards, unlike the 6061 I did last time. Gloves are a must working with 7075.
- I put a vacuum on the buffer tube hole, and held a low-pressure air nozzle at the magwell. This cleared chips very quickly and resulted in a much easier time and nicer finish.
- The through-pins on the KE Arms jig are for drilling only. Don’t put them on when you’re milling from the top. I’m down one pin because I milled right through it; luckily I had a spare.
- The previous times we cut in 1/8″ increments. I milled in 1/4″ depth increments and it wasn’t any harder. The feed rate was a little slower. I went for a single 3/8″ pass but there was chatter, so I pulled out to 1/4″ and it was smooth.
- It’s much faster to work alone. It took about two and a half or three hours to complete the mill owner’s lower. Mine took a little over an hour, including a break.
- It’s easier to make mistakes alone, too. I realized the previous night I needed to take care of the pin I ended up milling through, and I was super careful on the first one to point it out, but when it was time to do mine I was in a hurry and now I’m down a pin.
- The liquid squirt bottle of BOE LUBE is absolutely worth the cost. If I’d had five hands or so, I would have dripped BOE LUBE into the work.
The quality of the KE Arms lowers is fine. I got them on sale. Previously, I completed a BRS lower which I like much better (the integrated trigger guard, threaded mag catch, threaded takedown pin hole). However, the BRS jig is not as nice, and I wanted to try another maker’s setup. I thought I would like the steel bosses for the drill work, but it turned out to be easier to flip the jig over and come in from the left side as the bosses are not perpendicular to the jig surface.
If I do this again, I will probably buy more BRS lowers and make a transfer of the template to the top of the lower instead of using metal templates.
Buying magazines at reasonable prices from people that are selling them. Not as fun as buying them in bulk prices and selling them for panic prices, but so far I’m plus 30 30 rounders. No plans to stop.
Well, maybe if I score one of those 2500 magazine skiffs from MagPul. Maybe.
Watch from about 03:45 forward. Guy goes from engaging in a gun battle (one way at that point) to out like a light (literally, a headshot). The video isn’t graphic, unless seeing someone die is graphic. You can’t really see any gore.
were the worst part of Amigas.
In other news, I think I’ll dream of an SR25, even though I don’t want one.
If I could find a Cobb MCR-400 in 300 win mag, though, that would be nice. I’ve only known one person that had a pre-Bushmaster Cobb, and it was a 300, not a 400. Still.
Time to start saving pennies. Threaded for silencers from the factory, eh?
The owners of AR15.com are selling a huge stack of firearms to finance the move to Dallas. If I had a spare couple dozen grand, there are some nice rifles I’d pick up. The list is growing as time goes on, so watch carefully.
Factory 223 from at least 2011. Tempted to get a box to play with.
These guys have no idea. I’ll save you the trouble: they put it in a pile and shoot it from way too close.
