  1. Good for 45acp review by Brian on 5/14/2017

    I built a 45acp blowback upper for this lower, and it works great with all brand of high capacity mags that I have tried.

    I also built a 10mm blowback upper, and it cannot reliably feed with this lower and standard glock mags. I am getting near 100% failure to feed. I think the angle between the mag feed lips and the barrel chamber is way too steep. I am using a KVP 10mm barrel.

  2. Great product review by Mainah on 3/20/2017

    Purchased GLF lower, bolt, and 16" barrel. Function is superb, ejection works well.

    Wolff extra power spring and 7 oz. buffer per QC10 FAQs, this is a good combination.

    Notes- spring causes a noticeable increase in pull force to cycle bolt to charge from a closed action. Not excessive, just more.

    Greater reciprocating weight from heavy bolt and buffer, a little more rifle bounce and extra half second to get back on target compared to standard AR pattern rifle. Slower cycling time from blowback operation.

    More gasses and powder spitting than from a locked breech action, enough to notice. (Left handed shooter)
