Building my first AR, and making it an SBR. I'm looking at the "Model 1 Sales 7.5" upper.....anyone have any experience with their uppers, negative or positive? Thanks as always!! |
| Just assembled a kit for a friend. 20" govt profile A4. Upper seems to be of good quality but the LPK could have been better. The FSB is not a F type so the extended post had to be used. Test fired it w/several types of ammo, handloads to Wolf and all functioned fine. |

My 1st build was a M1S 16" carbine kit. The LPK left something to be desired, I had to shave down the safety selector detent for it to fit. I started to have FTE issues around 1000-1500 rounds and upon inspection of the BCG I saw that the extractor was way worn down. I replaced it with a CMT bolt and had no further issues. Other than those 2 glitches, no issues at all. |
