Looks like a good parts list. I would suggest you add an adjustable gas block if you are running a light weight BCG, or you will be over gassed. If you want to save some weight on the optic mount the Aero Precision mounts are light, but a bit of a pain in the ass to get the scope level with.
 
For anyone looking at what I think is a Norgon style ambi mag release from TNA, I was unable to successfully release the magazine using the ambi side. The part worked fine as a normal release however. YMMV

That's interesting to hear... Can you try loosening it by a rotation or two and see if it will function then ?
 
I tried both installing to where the stud is flush to the top of the button (BAD extended), as well as backing it off a turn. Unfortunately I mailed the part back today so I can't test further.
 
I'll try an actual norgon tomorrow for you.
Honestly, TNA resells a lot of Chinese copies, and the parts I've seen first hand may look the part, but the quality is definitely questionable. They seem like a good group to deal with, I just wouldn't buy anything from them that wasn't a well known brand name item.
 
I had bought one of TNA's "Norgons" and while they sell some quality budget parts at a market discount, this release is not one of them. Fit was what you'd expect but the button was gritty to the point of being unusable presumably due to some burr in there somewhere. Do not recommend.
 
If you’re interested in knock off parts at a price consistent with their quality, download the wish app.... I’m pretty sure the junk is coming from the same Chinese source, so why pay 400-600% markup on garbage.
I definitely don’t suggest using cheap junk on a firearm, but I’m also against a retailer selling knockoff crap at a massive mark up.
An example is their “ premium charging handle “ that they sell for 60$... wish sells the identical one for 10$ shipped from China... and I do mean identical. Save the extra money and buy a quality unit instead
 
Anyone planning on running a 7.62x39 upper?

I know 223 is relatively cheap as is - but for lots of trigger time, hard to beat the cost of surplus 7.62.

Personally, I’m fine shooting/hunting a deer with a 223, albeit I know the argument for some is ‘how humane’ is it.
I’ve got my stag10 in 308 as well, but the practical part of me wants everything rolled into one.

223 is my go to for long to mid-range precision matches. 308 is also another favourite for long range, but for trigger time it’s definitely more costly.

Thought about 6.5 Grendel, but it gets back to the $/round cost

Reloading knocks the cost per round down huge plus the added advantage of tuning a load perfect for the rifle and. I reload 223 for $320 per 1000. That's pretty cheap. I'm pretty sure a person could get the cost of grendel ammo down considerably. $1.75 per round including the cost of the case which is $1.18 of the cost. So if you reload 5he cost goes down everytime. And if you get once fired brass at a discounted price it's even better or buy hornady ammo and not include the $1.18. Without the case price its 57 cents a round for grendel. That's cheap.

Wasn’t sure if semi auto reloading was worth it.
I do tend to reload for my 223 and 308 bolt, but I don’t put out many rounds per hour as someone with a Dillon, as I use a single stage.

2019 I am carving more time out for myself, as the last few years have been sunk into work-work-work (joys of being my own boss though).

How long will brass last in the semi-auto?
I always found the tedious work of trimming and deburring the most time consuming to get the brass just right

Whereas at gotenda I could pick up a case of 1000 .223 for $329 (on sale) and stock it deep
7.62 bulk is on average 15-25c/round - which is hard to beat for no time out into it.

But the obvious downside is the lack of accuracy with it, and ballastically the 7.62x39 definitely isn’t the same as a Grendel
Moreover the lean towards the 7.62 would be for luxury of laziness and the cost effectiveness

There are lots of brass trimmers that cut down prep time immensely. I have a frankford arsenal powered prep center with a trimmer on it. Makes prep work 1000x less terrible. Chargemasters are also a life saver. I will never be without one now. I want a progressive for 9mm and 223 but I wont be buying a dillon. The lee loadmaster is finicky but for the price I'll deal with finicky and the powder measures are very very accurate.

Proper brass prep will extend the life of it greatly. Oversizing is the main killer of brass. If you anneal and minimally size the case they last for a long time if you dont run them to hot. Cant run to hot in a semi or you risk damaging the rifle after prolonged use. The bolts cant handle over pressure rounds like a bolt gun can. Plus primer pockets get sloppy on the case.

I usually prep brass one day and load the next. I can usually make about 600 rounds a day on a single stage if it's all been prepped.
 
With reloading for a semi, you must small base resize, so you are working it as much as possible. But you'll still get many loadings from each case.
It's easy to get 223 to under 300$/1000, and you'll end up with more accurate ammo than the cheap bulk stuff.
As far as using a Lee, vs buying a Dillon...... Save your money and your sanity and just buy a Dillon, you'll thank me in the long run.
I also do allot of brass prep for friends and even the odd " customer".. quality tooling makes all the difference.

Going with the 6.5 grendal is a reloaders specialty, and if you happen upon a stash of 7.62x39 brass, you can convert to grendal... I recently bought the tooling to do this, but haven't tried it yet

I've been have fantastic results in my stag 10 with shoulder bump neck size. No failure to feed no jams.. it has a min samii spec 7mm-08 chamber. Results may vary but I haven't had any problems. Some chambers need small base some dont. That's the best thing about reloading. Experimenting
