I love mine. Turn the buffer tube till the buffer system is right up against the bolt or as close as you can get it. I have some delrin rod coming to make a short stroke kit for it since my PSA AR-V uses CZ style mags and I don't need the bolt running full 223 length to cycle or lock open. Hoping to shorten the stroke and eliminate the occasional failure to eject that falls behind the bolt stop and bolt face. Shot make it a nice quick PCC. Run mine with a Banish 45 and with my 147/titegroup loads, it is stupid quiet and accurate.
