    I received this item and installed it on my new gun. I am so impressed once again with the quality and features. I have other Holosun RDO but this is my favorite by far. Much better and faster to acquire than the small red dots. I would highly recommend this one over even my other Holosun units. I hope that they expand the product line. In addition to the great product, I would like to thank Tim Silva for the awesome customer service. You are now my source for all my others.

    I was very pleased to find you had the Green Vulcan Reticle in stock. I ordered in the morning and by noon had a tracking number. Superb service. Easy to reach and correspond with. E-mail, and Facebook, very responsive. They’ve got my business going forward. This optic is now on my Walther PDP Compact 4″ EDC. Thanks TACRIG

    Incredibly fast shipping, from Oregon to the beaches of North Carolina in three days. I think the ACSS reticle is going to take my shooting to the next level. I have a eye disease that causes really bad astigmatism and the point of the chevron gives me a precise aiming point! I will order from here again!

    For a first time online purchase, TACRIG was great and exceeded my expectation. I ordered the Holoson 507c with Vulcan Retical and it works as advertised on my new Walther PDP. Received the item within a week and in great (new) condition and the price for this item was better than other online merchants. Will definitely do future business with TACRIG!

    This is the second holosun 507c ACSS I’ve purchased through Tacrig and I wouldn’t hesitate to order another through them. As for the 507c, I can’t say enough good about this optic, it’s definitely a game changer for those with vision impairments as well as those who are learning/new to using optics. Highly recommend checking out any of the ACSS reticle options from Holosun.

    It was my first time ordering an optic online and I was pleased to see this optic was available at a good price. They provided me with a tracking number the same day of the order plus it only took 3 days to arrive to Florida. Customer service was absolutely phenomenal and very responsive. Definitely recommend this company to anyone looking for optics.

    It was my first time ordering an optic online and I’m pleased to say I wasn’t disappointed. Firstly, this optic was hard to find anywhere for a decent price. Secondly, their shipping is super fast. They provided me with a tracking number the same day of the order and I received my optic 3 days after. Usually other companies take at least 5 days to ship to Florida. Also the customer service is phenomenal and very fast responding. I definitely recommend this company to anyone who’s in the market for optics!!
