I purchased as a new factory assembeled gun. Like i said in another post, machining looks good, fit not so. . Put a gold trigger, M4-72 Brake, Viper HST scope and mount, aligned the floating handguard. Shoots a good group with old brass, different powders different bullets. Only bad groups came with BL-C2. This is the last issue to work out. Thanks

Im thinking Anderson has some of those parts bins..

Ill pull it apart and measure everything i can, thanks!

Hello, Matt It is running back plenty far, it chambers the next round and then jambs the spent round on top of it. The photo is simulated, I thought after I was done shooting a photo would be easier then trying to explain so I staged it, I'll look at the case mouth next time. All the other case mouths of the ejected brass have that little dent, similar to my BAR. Hello, Robo The bolt catch would not rotate on the pin far enough to engage the bolt face, even when I manually retracted the bolt and pushed it in by hand. I know, seems strange but either it was drilled wrong or milled wrong. Hello, 98Z All internals are Anderson Manufacturing. Overgassing is possible Definitely not undergassing, always strips the next round from the mag and always locks back (after I modified the rotation range on the catch) Thank you all for the input. Thinking an adjustable gas block, low profile, any recommendations?

Extractor clean and square, ejector good. All like new. No visible defects, where would I find the spec on the groove width/ depth/ placement? Thanks

New here, lots of long guns and short guns but first ar10. Started with an Anderson AM10, refitted the floating guard and dremmeled quit a bit of material off the bolt catch before it would engage the bolt and lock it back, my impression of the rifle is overall good machining but poor fitting. Added a nice scope, trigger, and brake, shoots close to 2 in at 200 yards with misc headstamp twice fired brass loaded on my dillon 650, only problem is 1 in 10 ejected shell turns sideways case mouth out and jams on the fresh round. Tried more and less powder, different powders, different bullet and weight, same results. Tried new starline brass. Tried factory ammo. Sometimes 20 rounds, sometimes 3. What 's next to try?
