SKU: ReliaBoltPLUS Categories: , ,



The redesigned lugs of the Relia-Bolt™ virtually eliminate the most common MSR malfunction; the bolt to barrel extension jam. Haven’t cleaned your rifle? Is it out of time?  The patented Relia-Bolt™ compensates by providing a  patented camming action which guides the bolt past obstructions and into battery. (U.S. Patent No. 9,863,729) The rounded/tapered lugs push past carbon and debris when the square edges of traditional bolts would typically jam. Once into battery, the rear edges of the lugs fully engage the barrel extension for absolute strength and security.

Unmatched Strength and Durability

The Relia-Bolt™ is machined from S7 tool steel and tempered with SRC’s proprietary heat-treating process, significantly increasing strength when compared to MilSpec Carpenter 158. S7 provides a 75% increase in tensile strength, and nearly 60% improvement in yield strength.

Superior Corrosion Resistance
Every Relia-Bolt™ is coated with NP3®/NP3+® , an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon™, for self-lubricating corrosion resistance. NP3+® offers far more corrosion resistance for marine and other hostile environments. NP3+®  gain up to five times as much corrosion resistance over standard NP3® and up to 10X more than regular electroless nickel!

100% Compatibility
Our  Relia-Bolt™ is drop-in compatible with all existing .223/5.56 variant parts groups and bolt carriers; no modifications or tools are necessary for installation.
MPI, HPT, and Shot-Peened
Magnetic Particle Inspected, High Pressure Tested, and Shot Peened, the Relia-Bolt™ is guaranteed to perform under pressure.

We offer a 30-Day Money Back Guarantee on our complete line of Sharps bolt and bolt carrier products.

Lifetime Guarantee

If any Relia-Bolt™ is found to have defects in materials or workmanship, SRC will repair or replace it at no charge.

    Only shot with it once so far out of an SBR. No issues so far and the customer service is excellent. They answer any questions you may have very detailed. One thing I did notice was with my stock bolt I would have to lube it up sometime during the shoot after a few hundred rounds, or I would get an occasional malfunction. Got none this time around with the relia-bolt, not one drop of clp all day this time. Cleaned very easy too. So far so good.

    The NP3 PLUS bolt is finished amazingly well. Went into a Nickle boron carrier and functioned flawlessly. Can’t speak of reliability yet. (Hence 4 stars and not 5) After a few hundred rounds I will review again. Only bolt I will ever purchase again.

    The bolt works perfectly. Only time will tell if the s7 steel and np3 plus coating will hold up. What I really want to talk about is customer service. I had a little mix up with my order.

    Great Bolt system.
    I have 4 now and would not run an ar-15 without them.
    I fire a lot of rounds and the Relia-Bolt is by far the best in the industry.
    I also have the balanced bolt carrier, GREAT ALSO.
    I dont think you will be disappointed.

    Bought one a year or so ago for my Spike’s Tactical carbine. Recently bought a second Relia-Bolt for my Palmetto State Armory mid-length. I’ve never had any issues with my Relia-Bolt, & it cleans up easily. I still add a tiny amount of lube to it just out of habit, but I’m not sure it evens needs it. Bottom line…I will have a Relia-Bolt in any AR I have from now on.

    Bolt arrived very quickly. Excellent fast and courteous customer service. The bolt dropped right into my DPMS Oracle 5.56 with no problems. I haven’t been able to put very many rounds through it with the Relia-Bolt installed yet,only about a 100/150 or so. That’s not really enough to give it a complete evaluation, but I have tested it as best I could so far, using federal 5.56 and PMC Bronze .223 factory ammo and reloads. Shot it both standard (slow) and rapid fire including double and triple taps. It has performed 100% reliably. No problems or failures of any kind. I like to run my AR wet, and it cleaned up with little effort. So far I am very happy with the performance of the SRC Relia-Bolt. Bought it on sale and was very pleased with SRC’s customer service and the very reasonable cost of the bolt assembly with the NP3 PLUS coating (additional $10, but worth it in my opinion).

    Works perfectly. I’m very happy with my purchase to the point of replacing the existing bolt with the Relia Bolt in every one of my rifles. This is a great product. The price point is perfect at $69. Probably wouldn’t have purchased if more than that.

    I swapped to a single piece gas ring in the NP3 Plus Relia-Bolt, and installed into the factory carrier in my DDM4 V11 LW. The only other internal, functional change to the rifle was a braided wire H1 buffer assembly. I’ve fired approximately 900 rounds in the past three months without a hitch. No extended “torture tests,” just regular maintenence after each outing and a more thorough cleaning after a few 2-gun matches. The lugs and sides of the bolt easily wipe clean, however the tail still requires a scraper to get at the carbon, as expected. Very slick surface! No negative issues to report so far. Function has been flawless, and I like the added confidence that this bolt may help keep my rifle running for extended periods and/or in exceptional circumstances.

    My 25-45 is one-year-old with about 600 rds,built from scratch.With a Omni hybrid lower and Aero precision upper.This was a cheap build with most of the money in the barrel. I did not expect it to print tight on paper. However it has given 1″or better at 100yd with five shot groups with Sharps 87 gn FMJ and hand loads. With the new addition of a Relia bolt in NP3 PLUS makes this a real joy to shoot and so easy to clean up and the cycling of the action is noticeably smother going into battery. Reloading and bumping 5.56 to .257 can be done with the full length sizing die. the only thing to watch is OAL for fit in the magazine. Have used AR-COMP,CFE223,IMR 3031,H335,all are good and have had no FTF or FTE. With a 20″ barrel the velocities are good. Why shoot two or three times with 223 when you can do the job with one round of 25-45?

    I originally purchased the complete NP3PLUS bolt carrier group and was beyond satisfied with it. This time I purchased only the bolt to complete a NIB carrier I already had. I’m sure this will be a outstanding set up. The Sharps Brothers parts have been well worth the price paid. If I take on another AR build, these parts are going to be the first ordered.

    I have not used the “Plus” yet, but I have been using the standard relia bolt for years. They (Sharps) even noticed a failure in some from the batch I bought amd shipped me a new bolt with a return label to send back my old bolt. I mever had a problem with my bolt but SRC stands by their products. I would buy without hesitation.

    The best Bolt and I’ve ever owned. Tough as nails, I’ve run about 10,000 rounds through mine so far and only had one ejection failure. That was more due to my running it very hot though. The NP3 Plus coating reduces the need for oil and makes the entire thing run like clockwork. I would highly recommend picking one up if you get the chance.

    Had a firing pin hole in a previous bolt that was oblong. It started piercing primers and eroding my firing pin. I replaced the bolt with this and replaced the firing pin. Problem solved. They say you can run the bolt without lube, which is fine. I lubed it anyway and it’s running like a top. I just wished they sold individual BCG’s. I’d like to pick up one up to go with my bolt.
