Looks awesome. Can't wait to hear the range report.

Just remember, you will have varying/inconsistent POI when you put front sights on the free-float hand guard. Especially if you use a bi-pod.

Ok so after so real nice GunBroker crap dealer drama and having to mail the upper back to get the fore-rail fixed correctly this is how she is sitting, and probably will not be changing anytime soon

The range report today I am pleased to say was fantastic! I don't know why everyone is so hard on these AR15's in 7.62x39mm, I built one, and it went threw about 200 rounds today with no fail to feds or extracts. Although I may buy an enhanced firing ping, as I did have a few duded primers, even double tapped them and still no boom, out of 200 shots maybe 10 or 12 failed to fire. Used Tull Ammo 123gr steel case, and doped in for 100 on a 25 yard range basicly 2.5" high over center @25 yards. Here's how she shot off the bench, I was rather surprised with the groupings, shes a shooter :machinegun: for sure and I couldnt be more happy with it

Over all the platform itself is fantastic, an AR15 is an AR15 is an AR15 it seems. I know this marriage of platform and caliber is "unholy", however I have shot many AKs in my day as well, and I honestly think the the AR platform does the 7.62 a little bit more justice as far as accuracy goes. As long as you are willing to take the time and find the best price on the level of quality parts you want, your weapon should perform as you want it to. I also feel that the Spike Tactical ST-T2 Buffer I installed made a big difference with the follow up shots. It was very smooth threw the cycling(slow or fast) of rounds and with the recovery of the recoil. I personally went into today not knowing how this thing was going to to turn out, but I am really pleased to say that the picture above says it all. I know there will always be people who say its going to be problematic, or its a poop combination of platform and cartridge, but I will tell you it seems to work really well.

End verdict: Build an AR47, you'll love it

I am not going to pooh pooh your rifle, you like it, you love it that is all that matters. I will however offer you some advice. keep a close watch on your bolt's locking lugs. because of the larger diameter of the casing it leads to the bolt's steel being thinner in a high stress area. clean it often and check for cracks. Another thing is the way you have the scope mounted with one ring on the upper receiver and one ring on the keymod handguard. I think you are going to have some troubles with it not holding a good zero and possinbly working loose. I would suggest moving the scope back getting both rings on the upper and extending the buttstock or looking into a cantilever scope mount setup, a good example of which is right here: http://all-in-general.com/product_info. ... s_id=67243

The scope was fixed before we shot, that picture was just a rough fit up the day the before just to figure out eye relief. And yes I agree that the larger caliber with put more wear and tear on the internal stress points, and it is essential to clean and inspect this type of rifle as best and as often as you can. like before shooting and after cleaning I would have gone with a cantilever style riser, but I haven't had much luck with them in the past. Either they work them selves loose, or my favorite, something catches the leaver in the woods and it falls off.... So I am just going to stick with the 1" traditional weaver style rings this time.

But I do say well put points when dealing with the larger multi cal AR families(.300 BO/ 6.5/6.8/7.62), especially the stress points as it was originally made to handle the much smaller .223/5.56 mm cartridge.
