I haven't shot with this yet, but it looks great so far.
This look pretty much identical to a Toolcraft, so to my calibrated eyeballs it seems to be well within spec.

It looks great literally better than what I was expecting. Ready for a fresh build and eager to put some rounds through a fresh build.
USExcellent value for a 308/6.5 BCG
Purchased one of these BCGs while it was on sale to complete a 6.5 Creedmoor build. The dual ejectors and smaller pin were also a nice feature. This BCG is really the only "budget" part on the rifle, other than the discounted Stag-branded receivers I got on an overstock sale from Aero. I took a chance, figuring at worst if it headspaced or cycled poorly I could get a better bolt to put in the carrier and write it off to lessons learned. I've now got about 100 rounds through the gun, with zero cycling/ejection issues, good headspace, and great accuracy. Most of the initial rounds have been break-in followed by load development so accuracy varies by load, but most were 1 MOA or better with the best being between .6 and .7 MOA. I've had great luck with this one so far, and don't plan on needing to go with something else. I think this one will work just fine. So far, happy with the part, the price, and the good communication and quick shipping from AR15 Discounts. Build info: Aero upper, lower, rail.

Hi I have not used this product yet but purchased a matching barrel and everything seems well machined and fits together nicely.
