Front sight on hand guard

As far as You're loads the Ar can be loaded with over a 100gr and I have seen a few 120's bullet weights bullet weight is not so much an issue as the powder, Stay away from ball powders and use flake or perforated powders, as far as how fast you want it to burn depends on how long You're barrel is and were the gas port is located( rifle length, carbine length, Mid?) A good factory bullet that I have very good luck with is federal match, with the 79gr Sierra match king Hollow point boat tail Most of the guns I run it through will cut four or five holes that touch at 200 with good optic and rest. You can get MUCH better than 1.5 with an AR without allot of money going into it by starting with a free floated barrel just floating it 90% of the time in my experience will cut that 1.5 down to a .75 at 100 using factory ammo. Next good sights Metal or glass You're choice, then the trigger. I find the sights to be the hardest part, I like to get the front post out as far as I can Just to make it easier to see, I would stick with the original barrel mounted post sight and attach the sling to the free float tube, then You can Yank on the sling without any noticeable shift in P.O.I. because the FF. is attached the the barrel extension on the receiver and does not touch the barrel. I again really suggest the book I mentioned in my last post for building LR rifles for service rifle, varmint, target, or just getting a good shooter You can really on to shoot extremely well. I You are building a "tactical" rifle You can still expect it to help but in a different application, also goes into reloading theory and covers things that You really need to know for instance the Very low drag bullets (vld's) Molly coated bullets and such which Load COMPLETELY differant than "normal" bullets, Helps You keep You're fingers. IDK if You are going to take it that far though but I still suggest it.

I've ordered "the Mouse that roared" I should get it in a day or so.
Current status "screwed" the dog might need surgery.. I saved out some cash though and picked up an A2 20" HBAR in 223, I'll be looking forward to shooting it this weekend with some reloads a friend has offered up.
Once the dog has (hopefully) passed what shouldn't be in his belly I'll be looking to build a "tactical" type rifle with a 16" barrel that I can still mess with at distance.
This brings up a question about the length of the gas system. Wanting a short barrel but also wanting the sight radius to be as long as possible AND also wanting a front sight fixed to the barrel would put the gas port way out on the barrel (rifle length gas port). To me this would subject the bolt to less pressure and likely lessen the "violence" felt as the bolt unlocks and move's. And maybe improve accuracy.
I'm sure a barrel guy could tell me if I was barking up the wrong tree but the thought came to mind and now here it is.

The farther out You putt the gas port the more pressure You will have to operate the system since it will give the powder a longer burn time creating more gas before it bleeds of witch also means Higher pressure. Witch means in a longer barrel You can get away with slower powders in a short barrel You will need a faster burning powder to created the High pressure needed in a much shorter distance. Just some food for though Until You're book gets in which will clear up allot of You're questions but the side affect of that is it will only leave You will more and You may find You're self doing allot of experimenting! Sounds like You are gonna have allot of fun though, I DID! I just ran outta money! Have fun!

You have any interest in Service rifle shooting?

Our healer did the same thing, She ate one of those "indestructible" Kong balls cost us 3k to have 18-in. of her intestine removed, I have vowed against expensive med. attention for dogs ever again.

This one thought a disposable razor would be a tasty chew toy ?!?!?!

Service rifle shooting? It's funny you mention this. Years ago I was heavily involved with match shooting, the last "game" I played was Black powder cartidge rifles, I was a Master, shooting 35's-37's regularly (of course I got my butt kicked at the Nationals and other "other" Ranges.
Anyway back on point, yes I want to get back into match shooting again, now that the kids need me less I'll have time.
Time to practice! Are you currently competeing?

[Backinblackrifles]

NO To many other responsabilies that require My money, But I would like to get together with someone who have a love for accuracy and precision without all the fancy gadgets focusing more on form fit and function.

And my match rifle got snatched outta my car. She was purty!
