L.A.R.B. H (heavy, 4oz) AR15 carbine, anti tilt recoil buffer assembly. For use in mil spec carbine length receiver extension/buffer tube only. Uses mil spec carbine length recoil spring. 100% 17-4 stainless steel, lifetime warranty. Requires hole in rear of bolt carrier to be mil spec size of 5/8″ (.625 +\- .005). Compatible with most BCG on the market. Compatible with DI and piston rifles and SBRs. We highly recommend SprinCo recoil springs when using the LARB recoil buffer. SprinCo is the only recoil spring we’ve used that match our quality control and performance. When the Armament LARB recoil buffer is paired with a SprinCo recoil spring, you have an EXTREMELY effective recoil management system. The best in the AR15/M4 shooting industry. This is something that has to be felt and shot first hand to understand what a well engineered, balanced recoil should feel like. A smoother, flatter, reduced and controlable recoil is what you feel IMMEDIATELY with the LARB recoil buffer. We offer the LARB recoil buffer and SprinCo recoil spring as a package as well. Please let us know if you have any questions regarding recoil buffers or springs.

Available on backorder

SKU: larb17 Category:


As stated, these are currently back ordered. We’re constantly getting components made and buffers assembled and back orders are being filled, but we’re behind demand. Typically all back orders are fulfilled in 3-6 weeks from date of purchase (if not in stock). I would highly recommend placing a MOD2 on back order as we sell them faster than we can make them, get in line to make sure you get one! Thank you!

    Fit & finish are flawless. Excellent product made by a great guy. Works well in my Colt 6921 rifle and tames recoil as advertised. Pairs well with a Super 42 Braided wire spring from Geissele

  2. Rated 5 out of 5

    I thought the internal diameter of the Geissele Super 42 Braided Wire Spring was smaller and would only work with factory modified Geissele H2 buffers. How is the fit using that combination? I wanted to purchase that spring, but didn’t because it wouldn’t fit a L.A.R.B. buffer.

    • Hello, we have a braided recoil spring here that we use with a LARB in our M16. It has been working well.

  4. Rated 5 out of 5

    I absolutely love these, got one in a rifle I bought second hand and am about to install in all mine: question is this, has anyone used these with the FRT-15 triggers? https://www.rarebreedtriggers.com/product/frt-15-br

      We have a lot of customers running the FRT and our LARB buffer.
