Reliable Rifle Bolts by Failzero in US specification & supply

US gunsmith supply: Drop-in bolt has a self-lubricating surface that eliminates the need to apply oil or grease that can attract dirt, dust, unburned powder, and carbon and lead to cycling failures. Proprietary exo treatment produces an exceptionally hard surface that's 40% more wear resistant than chrome plating, with an ultra-low friction coefficient. Surface is actually harder than the substrate underneath and will not peel, flake, gall, or rub off. Exo-treated nickel boron finish bolt/carrier groups have been tested to function reliably without additional lubrication up to 50,000 rounds. Reduced friction also means less heat generated by metal-on-metal contact, so the gun runs cooler and parts last lo mfg: failzero specs: heat-hardened carbon steel, exo-treated nickel boron finish. Fits mil-spec ar-15 upper receiver. Find here reliable & durable gunsmith supplies including rifle bolts by Failzero. US supply MPN: EXOBOLTASS01.

USD 213.95
(Indicative price - actual current price possibly lower)
Rifle Bolts US Specs & Supply
US gunsmith supply: For anyone using .308/7.62 ar-type rifles, it is common knowledge that many factory rounds exhibit excessive primer flow and/or ejector smear. At its core, this is a result of ammo development being done by manufacturers only for manual platforms without testing in semi-auto platforms. Some rifle manuals even record the maximum recommended load data beyond the functional range of these rifles. Unfortunately, these issues will persist until the manufacturers of ammunition realize that an ar platform requires a unique pressure curve to allow for both accuracy and reliability. Manufactured to the exacting standards of our standard bolt offerings, the high pressure enhancedbolt des mfg: j p enterprises specs: sae 9310 nickel-chromium-molybdenum steel, chromium nitride. Fully assembled with extractor, gas rings, ejector, pins, and springs installed. .308 fits dpms/ar-10 style rifles. Find here reliable & durable gunsmith supplies including rifle bolts by JP.

Lwrc International Ar 15 Advanced Combat Bolt Assembly 6.8 Spc Ii/224 Valkyrie Advanced Combat Bolt 6.8mm Spc Ii/224 Valkyrie US Specs & Supply
USD 54.99
(Indicative price - actual current price possibly lower)
Rifle Bolts US Specs & Supply
US gunsmith supply: Updated design of the standard ar-15 bolt features a fully supported breech face and a dual-spring extractor system for extra strength and reliability to handle the 6.8 remington spc ii or 224 valkyrie cartridge. Machined from an extremely hard steel alloy normally used in high-stress/heat applications like race car transmissions, then shot-peened and x-rayed for flaws before plating with a nickel-boron (nib) coating. Nib coating significantly reduces friction coefficient, so the bolt is less likely to be hung up by fouling, and wear-resistance is greatly enhanced. Super-slick surface makes cleanup easy because carbon and gunk have a hard time sticking to it. Mfg: lwrc international specs: ultra-hard steel alloy, nickel-boron plated, silver finish. Comes complete with ejector, extractor, and gas rings installed. Fits a standard ar-15 carrier. Find here reliable & durable gunsmith supplies including rifle bolts by LWRC.
