factory ammo or handloads? bullet weight? barrel length? gas system?(rifle, midlength, carbine). as others have said, your BCG isn't being pushed back far enough. this can be caused by several things by themselves or a combination of them. as above. too heavy of a buffer. wrong buffer spring, like a rifle spring in a carbine buffer tube perhaps. under loaded ammo, rare with factory ammo, more of a possibility with reloads. anything causing excessive drag on the BCG, like tons of crud in the action that hasn't been cleaned in ages. a partially plugged gas port or gas tube. a incorrectly adjusted adjustable gas block. shooting way undersized bullets (a handloading oops, which i would think would be obvious, but you never know, like loading 25 caliber bullets in the 6.5 Grendel. i wouldn't think that's possible but......)
