Hey all, So I bought a used stag upper awhile back, and it short strokes. I am new to the AR game but my findings tell me it is something to do with the BCG. One of the key bolts seems to be not flush with its factory stak mark. Both are staked, but the most forward one seems to be in a 11/4 position. Rather than its original 9/3 position. This tells me it moved, and is losing gas causing the short stroke. I am going to buy a BCM brand BCG. So hey, any of you smiths out there who need an extra BCG, this is for you. Price is $50. Is this a decent price? I am open to suggestions. Thanks. I am in Hollister and can ship or do FTF.
