DPMS LR 308 Barrel "break-in"..

RICE ETR

Well I bought this gun a few months ago but due to traveling for work, I haven't had a chance to shoot it...so what do you do with money and no time...BUY stuff! So I put a geiselle (sp?) two stage in it, accurizing wedge, hogue grip,and prs stock all on it before even shooting it. Lol I also bought 300rds of federal gold match ($19.95 per box!).

I have been searching and searching, trying to figure out if the break-in process was hog wash or not. I came to my own conclusion that in a custom, hand lapped barrel, the first shot is the probably the best shot...a factory barrel may require some smoothing....but I was still a skeptic and I believe more harm can be done to a barrel by improper cleaning than break-in or no break-in.

I decided I wasn't putting any rod down this barrel until I got a Lucas bore guide so after seeing the idea on the net, I made my own patchworm. .281" hole seems to fit nicely with the thickness patches that I am using.
I don't know how many rounds DPMS test fires but the last few inches that I could see of the barrel had excessive amounts of copper fouling. It took me about 45mins with butches bore shine to get it all out.

This past saturday I got the chance to shoot it, I had no scope or bipod so to wally world I went...I'll replace these items later. Don't knock my $70 Centerpoint scope, I'm going to see how long it lasts lol.
Anywho, it was hot, real hot here, about 95F in the shade. We set up at 100yds with a huge piece of cardboard and a target in the middle of it.
The only other centerfire I have ever shot before is a hand-me-down .270 bolt action, so I was curious about a gas operated 308.
First shot was (i guessed through scope) 15in low, 7 in left. I took a peek at the barrel, no copper...so I made adjustments then fired off the second round, 3in right, 1in high as you can see. Again, no copper so I continued without cleaning.
Again I made adjustments and decided to fire off three rounds to get a group.
If this barrel "breaks-in" and gets anymore accurate, I don't know if I am going to be able to stand it lol.
I LOVE this gun!!! and I have to mention that I also LOVE this gun!!! Such a sweet shooter.
I let my brother, his fiance and my dad shoot a few rounds thru it. I then shot another 3 shot group with two rounds almost in the same hole and one about an inch high and to the right....I then discovered a loose scope ring so decided to call it quits.
Sorry for the book, thanks for reading/looking. FYI I was so excited about the picture that I didn't notice the upside down box of ammo for the picture...lol...ahh well.
One question though, anyone recommend a good repair/upgrade kit for the internals? Cam pin, piston rings, etc? Prior to shooting I pulled it all apart and clean then lubed with break free and it cycled flawlessly but I just want to make sure I have extra parts next time I make it out to the farm so I don't have to end my day short.

Nice group. Get a DPMS parts kit for it that way you know it fits. The way it shoots, I don't think you need any more upgrades.

People hurt their guns more by overcleaning them than shooting them. Seems like the barrel is just fine with no break in.
 
Nice shooting, these .308 AR's are more fun then should be legal. I follow Noveske's cleaning recommendations of patch and brush travel in one direction only, chamber to crown. It's a pita with a brush but so far I've had no problems with copper that four or five passes doesn't take care of.
 
If the rifle shoots good and doesn't pick up excess copper I don't know that you would gain anything. But, it won't hurt anything either. If you use a bore guide and don't rake the bore at either end with the rod you can clean it until you are blue in the face and it won't damage the bore.
 
My buddy bought one last fall it shoots like yours but he had a few problems feeding or the bolt not closing all the way after about 60 rounds it was alot better now its his fav. nice little rifle:D
