Tho I haven't had a chance to fire flairs out of this yet I can tell you it is a well machined item. The threads fit well into the 209 primer trip alarms, the anodizing is uniform, and an experienced machinist can see sharp tooling was used, all indicates a quality shop made a quality product! And product support is 100% I encourage you to contact the staff with any questions. They are punctual with responses and very polite! A great company that makes a great product! P.s. Because of a change in laws by the BATFE, it's harder now to find flairs. So blame the GOV. for fith ops not selling flairs for this item, they can only comply with the law.
