Guess you didn't. It was a natural assumption since most unfinished receivers on the market are 80% complete. If you have to be going to all this trouble, why bother with a solid forging? Most of us don't have access to or knowledge of CNC equipment.

That's understandable. I work with bringing new products to market and it's not easy or fast if you want to deliver a quality product. In light of trying to make sure that everything is just right, perhaps the wait is a blessing. I'll keep an eye out, too. Making a complete .308 lower from an 80% is looking very much like my next challenge. I have access to a small milling machine, and have milling table on an old drill press in my shop. It could be an extremely interesting project, but some type of drilling jig is needed o get the trigger, hammer, and safety holes in exactly the right places.

I've never heard of rapid barrel wear in the .22-250. It can be a problem in the .220 Swift. But that round can crack out 50 grainers at 4k fps and maybe slightly higher. It's pretty cool that you can get away with using unmodified .308 mags in the .22-250 AR. A 1 in 8 twist will allow for the stabilization of heavier bullets, something the .22-250 should be quite capable of handling, one would think.

Wow! That would certainly be different. What were you thinking of using in the way of a magazine? Since the .22-250 is based on the .250 Savage case, it's more than likely dimensionally different (other than the rim size) from any caliber that the AR platform is currently chambered in. I would think that this would present some rather unique feeding issues. Come to think of it, the .250 Savage may not be a bad chambering in the AR in it own right.

That's interesting. About 20 years ago I converted a 30 rd. Orlite (similar in construction to Pmag) 5.56 mag from 30 round to 10 round by doing the same thing. I cut the spring down with a Dremel. I still have it and it works like a champ. Fits nice and flush with only the bottom plate sticking out. At the time I bought 10 of the Orlite 30 rounders for $65 in anticipation of a federal ban, so figured I could sacrifice just one. Never thought of doing the same to a Pmag. I'll have to pick up a few more (only have one right now). Thanks Horsemen!

Already been eyeing the heavy buffer by Clint. Not familiar with the carrier weight system. I'll have to poke around on that one.

Nice! I want one - oh wait! I already have one. Well I want another one then. :)

Me too! :) Now that it's built and close to being broken in I'm lookin to do a little tweaking in the recoil reduction department, not that it's all that bad now. It's easier on me than my HK91, which is heavier. And after 20 rounds or so, I end up literally with a bruised black and blue shoulder. Firing over 40 rounds in an afternoon with the AP4-not even sore.

I am searching for a muzzle brake on my .308 DPMS. I really like the muzzle brakes that Bushmaster makes for the 5.56, and I have one on each of the AR-15 Bush twins. It's the one modelled after the Russian design for the AK-74. They work well, cost less than $30, and don't create much side blast and noise. Unfortunately, Bushmaster doesn't make a .30 caliber version to my knowledge. Are there any .30 cal muzzle brakes out there that are effective in mitigating muzzle rise yet don't produce a bunch of blast and ear-boxing concussion? A heavy buffer is the next recoil-reducing device.

I recently purchased a DPMS 4 rounder for hunting from DPMS. By the time the dust settled, it was just a few cents shy of $60. Ridiculous! Pmag could definitely fill a niche here!

Good answer.

Hey no problem. I just got an invite from my sister and her significant other to head out on Sunday. They found a spot up off of Park Links Dr. Catch you another time. :)

Planeflyer - were you guys planning on heading out to do some stuff-blasting?

You're right about the cam pin. But I've seen the same thing on my Bushmaster 5.56s. So I was'nt too worried about it. Then I got a good close look at the locking lugs on the 5.56s - pretty much the same thing, just never noticed it. The 5.56 twins have been going for about 20 years without a problem, so I'm no longer going to worry about the 7.62. Just shoot it and have fun. Thanks guys for your input!

Next MG shoot is 30, 31 March, and 01 April. They also have one in October. I was there last October and some guys were lighting off the 76mm main gun on an M18 Hellcat WW2 tank. The muzzle blast was not to be believed. You just never know what's going to show up. Night shoots are pretty spectacular, that's when the tracer goblins and pyrotechnics come out. www.mgshooters.com Always seems to be a number 1919A4s and ma deuces that show as regulars. Sometimes muzzle loading cannons anywhere from about 3 to 5 inch show as well as a guy with a beautifully restored gatling gun in the original 45-70. Admission is $25 for a spectator for 3 days (actually 21/2).

Any of you Arizona boys ever attend the M.G. shoot just north of Wikieup on US93? It's held twice a year, and it's quite a bash.

Why thank you unforgiven. Hope to run into you here on the forum. Likewise mikedaddy and blue109.

I think you're probably right ,Dusty. In looking more closely, even though there's a "ding" on the rear of each locking lug, there still plenty of the original metal. It's not like the bolt is actually weakened. But, if I can figure out how, I'll upload a photo. The lugs appear to measure about .150" in width and appear to measure about .144" at the rounded edge. At the time of the photo the bolt head has a abundance of moly grease on it. I'm beginning to feel like a new doting father. Good suggestion on the photo upload Planeflyer.

I would actually gravitate toward the M1A loaded or NM. Unfortunately they're very expensive and out for reach for me. The next best thing is to build your own AR, which is basically what I did. There's simply no better way to learn the intricacies and the internal workings of your firearm. And with the endless options out there, you can get exactly what you want, although you may have to wait a while because in some instances the lead times stretch out there. The other advantage is that you can buy the parts a few at a time, rather than having to plunk down a huge sum of cash all in one outlay.

Planeflyer - sounds as though it could be interesting. NW side myself about a mile from the freeway - in the county but much of the area has (apparently) long been annexed by Marana for the tax revenues. Some weekends are free, pretty much out of the question during the week. Full, and I do mean FULL time job. Not complaining though.

Ouch! You could have an M1A for that.

It looks as though Sig has a new .308 AR platform piston gun ... http://www.gunsamerica.com/blog/sig-sauer-7-62-rifle-p224-doublestack-compact-551-a1-sbrs/

St. David, pretty quiet little place, at least whenever I've been through there. I believe it originated as an LDS settlement. I'm out of Tucson - the nuthouse - but hoping to retire away from here in a few years. Any more, one must drive too far to shoot.

Hello from another newbie, both to this board and to the .308 AR platform. Hope things are going well for you in the great free state of LA.

Just got my LR308 put together a few weeks ago and have been following the barrel break-in procedure. It's almost complete, with about 120 rounds of surplus US ball and American Eagle run through it. Yesterday when I was cleaning it I noticed that one rear corner of the all locking lugs on the bolt were slightly rounded, no longer sharp, square cornered as before. It's almost as if the bolt had rotated a degree or two too far upon unlocking and the corners snagged a bit on the adjacent locking lugs of the barrel on opening. I've had no problems with the rifle - it functions like a Swiss watch. But anything possibly affecting the locking lugs gets me a trifle nervous. The upper was purchased as a factory assembled unit. The lower was assembled myself. Anyone else seen this? Is it part of normal wear during "break-in" with these? I've assembled three Bushmaster AR-15s and never seen this, even after a couple thousand rounds. Maybe it's something inherent to the .308 version.
