Certified SR-25, Mk11, M110 Armorer

When it comes to URX installation, we think we do the best job in the industry. 

Installing a URX is easy to do but difficult to do correctly.  We are the first dealer to use a specialized vise with purpose made/proprietary extended jaws that ensure the rail is s precisely aligned and held firmly so no damage is done to the engagements of the aluminum barrel nut or to the rail and upper themselves.

We have specialized fixtures for properly removing pressed on gas blocks and other tools that we haven't discussed that make us uniquely qualified to quickly and safely perform work on both 5.56 and 7.62 platform URX rails.

We inspect and dry fit all parts before installation, clean and prep all thread surfaces, use only Blue Loctite 242, and apply the proper amount of torque.

We use the best tools available and follow a repeatable procedure.  Normally turn around installs within 24 hours.

Most importantly, we are trained to perform maintanence on your rifle without compromising your warrantee!

Title: Rail Installation Perfection

I have had a URXII Rifle Length, URXIII, and URX3.1 for me and all installations have been perfect. VERY fast installation turn around. I plan to use Boltcarrier.com for all my future Knight's Armament purchases and installations.

Title: Installation work

I had Ayan remove the old flash hider off of my sr25 and replace it with a MAMS. Communication was awesome and the work was clean and very well executed.

There are only two places I now trust to work on my Knights Armament rifles and that is the factory and Ayan at Boltcarrier.com

Keep up the good work sir!

Title: SR25 URX 3.1 7.62 Rail Install

I had a SR-25 upper with a URX 3.1 7.62 rail that I needed installed. Ayan was extremely responsive and turned my build around in ONE DAY. Before finding him, I had sent emails and left phone messages at a couple other Well Known KAC dealers only to NEVER even have the courtesy of a response. Some people are customer service oriented and SOME ARE NOT. I highly recommend boltcarrier.com as the "go to" dealer for any services/products.

Title: URX Install

There aren't many guys that have the tools or the skills to do this work. Ayan does the work for a reasonable price and does it well. Additionally, his turn around times are ridiculous. Each time I've sent in a rail install job he has received my parts, completed the install work, and shipped them back to me the same day. Excellent.

Title: Rail Install

Once again, Ayan has done a phenomenal job installing my rail. I have sent a couple uppers to him and he installs rails and ships them back the same day. I will continue to use Boltcarrier.com for all my upper modifications and needs.

Title: First Class Service

I've heard nothing but great things about boltcarrier.com and the work performed by Ayan. Although I've assembled some nice ARs myself, I wanted my URX II installed correctly and decided it was time to solicit the help from someone who has plenty of experience performing the work. I'm happy to report that it was the right decision. No regrets. Not only did Ayan do an outstanding job putting everything together, the turnaround time for the service was unbelievably fast. I shipped my upper on a Friday, he received it on a Monday. I received a FedEx shipping notice that very same day, and a few days later the upper was back in my hands. I was able to take it out the following weekend and give it a run, and it ran like a sewing machine. It really doesn't get any better. boltcarrier.com has definitely earned my business in the future and I won't hesitate to recommend Ayan's work and vouch for their outstanding service.

My gunsmith had screwed up my upper trying to install my URX, but thanks to Ayan it was all fixed. Thank you!

Title: Like new!

Ayan replaced the URX 3.1 on my SR15 and he had it back in my hands within a week. Well done!
Great work and very competitive prices on his parts.
I am not always the easier customer to deal with, but Ayan did it with as much grace as possible.

Title: URX3 - Reinstall

I twisted the URX3 rail out of alignment on my AAC 300 BLK upper when I was trying to remove the flash suppressor. Ayan was able to remove the flash suppressor, disassemble and reassemble the upper and get it shipped out all in the same day. I couldn’t be happier. The upper looks and works great.

Title: URX III Installation

I had Ayan install the URX III on my Aero Precision upper which was in around 2012 (just now getting to the review, sorry) but it was great. I won't have anyone but boltcarrier.com do my installs or other work on my KAC products! Oh and communication has always been 100%.

Title: Very pleased

I bought a KAC URX 3.1 7.62 rail from Ayan. After getting all the parts together I sent them to him for assembly. He quickly found that a few of the parts I sent would probably not function as I had hoped. Ayan knows what he is going and quickly ordered the correct parts and shipped it back. Not only does it look amazing, the rifle functions 100% without fail. Thanks and I will be back for more builds!

Title: Class Act

Ayan has performed many URX rail swaps and installations for me. The quality of the work completed has always been exemplary. There are many shops that do quality work (and many that don't), but for KAC work Ayan is the way to go.

Title: URX Install

Awesome work. Period. One of the best KAC smiths out there. I'm known as Mr. 762 on several boards and Ayan is the only guys who gets to work on my SR-25's.

Title: URX 3.1 Installation

Ayan completed a URX 3.1 on my old Colt and had it back to me in days! Installation was flawless as expected and I order any and all my Knight's Parts from boltcarrier (if he can keep them in stock!)Top notch service, Great to deal with!

Title: 7.62 & 5.56 URX 3.1

Boltcarrier has done 2 URX rail installations for me. Updated an older sr25 with a newer rail, and upgraded a 6920 upper. Both installs look flawless, and are still going strong. Ayan does great work, would recommend, would repeat!

Title: URX REDUX

I sent Ayan an AAC 5.56 rifle to repair the bad installation of the URX rail. Knight's Armaments recommends him as top notch. This was a new rifle that came from AAC with the rail mounted way off to the left. I returned it to them a total of three times, to no avail. They couldn't mount the rail straight. Ayan milled it and now it is fine. Also had him take off the AAC brake and mount a Gemtech suppressor mount for a G5. I love the rifle now, but getting it to where it is, all thanks to Ayan. He should be working for the US Government. I give him 5 stars for quality of work, quick turn around, and reasonable price for the work.

Title: Seekins rail install

I had purchased an AAC 300 blackout upper, with the Knights Armament URX rail,I sent my upper and the new Seekins MCSR rail and he swapped the out for me and did an excellent job with a very quick turn around, would highly recommend for any type of gunsmith work. Thank you for such a great job!!!!

Title: URX II 7.62 Install - Perfection

I recently had BC install a 7.62 URX II done on an Aero Precision receiver set. Due to the slight differences between the Aero Receiver threads and the rail, I opted for the "milled rail for seamless fit" option. The end result was absolute perfection. I will be returning customer to BoltCarrier for the quality work, great prices, and excellent customer service.

Title: Best KAC guy in the business

Ayan does the cleanest work on KAC guns bar none. URX rails can be a PITA to install. It requires a special wrench and can be hard to align. I sent me KAC CQB off to boltcarrier to have it professionally done and was not disappointed. Lightning fast turn around time, perfect work and great prices will keep me coming back here for all my KAC needs. Thanks again!

Title: Meticulous URX II Installation

I sent Ayan a BCM 11.5" upper with an installed KAC URX II 10" rail. There was a quarter-inch gap between the rail and the upper. Ayan meticulously installed the rail, with an incredibly tight fit to the upper receiver. Moreover, I had the upper back to me within a week. Ayan is a subject matter expert and professional on all things Knights Armament. I will be a repeat customer of his for years to come.

Great job of the URX install on my 308 rifle. Ayan milled the rail for a seamless fit with the upper. Great work as usual. Highly recommend Boltcarrier.com.

Title: Boltcarrier

You know, I don't like doing reviews. But spit on the campfire and call me a butt nugget if Ayan isn't the rootin'est tootin'est gun slinging' super freakin' all around best KAC certified armorer South of the Mason Dixie! Not only did he provide top notch service (as usual), but he didn't hurt my feelings by calling me a gay or nothin' like that. Ayan (yep, that's his real name) can carry my bolt any day.

Ayan has done multiple URX installs for me and every time the work has been flawless.

You have to be patient, but Ayan will come through!

Title: URX install

As always- Ayan did an incredible job on my KAC gear. Had him install a URX3 on my 14.5 upper- he relieved the front sight to close over the gas block, and it's simply a work of art. I don't go anywhere else!

Title: URX3.1 Install

Had Ayan remove and re-install a URX3.1 after seeing several projects and builds and the quality and attention to detail he has. My rail was still ever so slightly off-centered after being milled to fit flush to the BCM4 upper. He advised me of this via phone call, and said if the irons need an unusual amount of adjustment to compensate for it, more drastic measures could be taken. Needless to say, I can't see it with my eye and my irons were dead on. Great turnaround, comms, and clean work. Deal with confidence gentlemen.

Title: URX 3.1 Install

I sent my Colt LE6920 upper with A2 front sight/gas block to Ayan to have the URX 3.1 installed. I believe it's as close to perfect as is possible. I had it back days later, and the price for the rail with installation could not be beat.

BoltCarrier removed my old URXII from my SR25 EMC and installed a new URXIII. The turnaround time and quality of work done by boltcarrier can not be topped. I have had several URXs installed here and will continue to use these services. Best of the best of the best.

Thanks!

Title: URX 4 Installation

I contacted Ayan with an urgent request for installation of a Knight's URX 4 on an 20" AR-15 rifle. He listened to my description of the work needed and promised to complete the job in the necessary time. I needed the rifle for an event and did not have the luxury of missing my deadline. Once I made the decision to send the upper, I decided to have Ayan install SureFire muzzle brakes on two other guns at the same time. I let Ayan know I did not expect him to complete the work on all three by the deadline set. Despite the added work, Ayan completed all three pieces and my hardware was delivered ahead of schedule. Most important was the work quality. It was perfect. I would have been annoyed had it been anything less. I'll happily send Ayan my future work.
