The MCR is a different animal than your average AR, and when you're running belts through a belt-fed 5.56 upper, the small internal parts see a lot more work than they would in a standard rifle. This rehab kit from FightLite Industries gathers the exact bolt components that take the most abuse and packages them together so you're not scrambling for a single spring or pin when it matters. It's the kind of thing you toss in the range bag or leave on the bench so a worn extractor or tired ejector spring never ends your shooting day early.
Every part in here is genuine FightLite, built to the same spec as the pieces already in your bolt. You get the extractor, extractor pin, and extractor spring, plus the bolt o-ring, firing pin, firing pin retaining pin, cam pin, ejector, and ejector spring. That covers the majority of the wear items in the bolt group, which is why it earns the "rehab" name. Instead of ordering parts one at a time as they fail, you've got the whole set on hand.
The MCR is a short-stroke piston, closed-bolt system designed to fill the gap between a semi-auto rifle and a light machine gun, and it thrives on sustained fire. That kind of use puts real cycles on the extractor, ejector, and firing pin over time. Springs relax, pins wear, and o-rings age. Having factory replacements ready means you keep the gun reliable through long sessions without downtime waiting on shipping.
A quick word of advice from the bench: FightLite recommends these parts be installed by a qualified gunsmith. The MCR is a precise, purpose-built platform, and getting the bolt back together correctly is worth doing right. If you're comfortable working on your own guns, take your time and reference proper documentation. If not, hand it to someone who knows the platform and you'll be back to feeding belts in no time.
This kit is made specifically for the FightLite MCR belt-fed rifle system chambered in .223 Rem / 5.56x45mm. These are genuine FightLite parts built to factory spec for the MCR bolt group. It is not a general-purpose AR-15 parts kit.
The idea is to refresh, or rehab, the high-wear internals of your MCR bolt all at once rather than replacing pieces one at a time. It bundles the components most likely to wear from sustained belt-fed use, like the extractor, ejector, springs, and firing pin. Keep one on the bench and you can restore a tired bolt in a single sitting.
FightLite recommends that these parts be installed by a qualified and trained gunsmith. The MCR is a precise, purpose-built platform, so proper reassembly of the bolt group matters for reliable function. If you're experienced working on the platform, take your time and follow correct procedure; otherwise, hand it to a gunsmith familiar with the MCR.
Not necessarily. You can use only the pieces you need and hold the rest as spares. Many MCR owners keep the full kit around specifically so any single worn part, whether it's a spring, pin, or the extractor, can be swapped without waiting on a new order.
