Luth-AR MBA-1 Rifle Buttstock, Fits AR-15 and AR-10 A2 Rifle Buffer Tubes, Fixed Stock with Adjustable LOP and Cheek Rest, Black The Luth-AR MBA-1 is a fixed rifle buttstock for AR-15 and AR-10 rifles that use a standard A2 rifle buffer tube. MBA stands for Modular Buttstock Assembly. It drops in where an A1 or A2 fixed stock would go, then lets you set the length of pull and the cheek height to fit you and your optic. Most fixed stocks give you one shape and nothing to change. The MBA-1 keeps the strength and simple fit of a fixed rifle stock and adds the adjustments that shooters usually look for in a precision or designated marksman build. It weighs about 16.1 oz, it is built in the USA, and this one is black. If you are setting up a bench gun, a long-range AR, or just want a better cheek weld behind a magnified scope, the MBA-1 is one of the most common ways to get there without changing your buffer system. A drop-in A2 replacement with adjustable length of pull and cheek height, made in the USA. Fits A2 Rifle Buffer Tubes The MBA-1 is made for the round, full-length A2 rifle buffer tube. It works with both the .223/5.56 rifle buffer assembly on an AR-15 and the .308 rifle buffer assembly on an AR-10 style rifle. Luth-AR lists it as interchangeable with standard A1 and A2 buttstocks, and with aftermarket stocks that are about 10.5 inches long overall. It does not fit a carbine buffer tube. A carbine tube has a flat rail with adjustment holes along the bottom, and it is much shorter. If your rifle has a 6-position carbine tube, you will need an adjustable carbine stock instead, or you can convert the rifle to an A2 rifle buffer system. The stock does not include a buffer tube, buffer or spring. Adjustable Length of Pull The buttplate slides on a rail at the back of the stock. Collapsed, the length of pull is 10.5 inches. Extended, it reaches 11.5 inches, for about 1 1/16 inches of extra length. Two quick adjust knobs lock the buttplate in place. This lets you set the stock for your arm length, for body armor or heavy clothing, or for a prone or bench position. Adjustable Cheek Rest The cheek piece rises up to 1 inch when fully extended. It also slides forward and back on the stock, so you can line your eye up with a scope that sits high or far back on the rail. A good cheek weld helps you get the same head position every shot, which matters more the farther you shoot. The cheek piece ships set up for a right-handed shooter. It can be moved to the other side for left-handed use, and the rest of the stock is fully ambidextrous. Bench and Sling Features A molded-in bag hook under the stock lets you rest the rifle on a rear bag and pull it in tight for a steadier hold on the bench. The stock also has molded pockets on both sides that accept Grovtec self-tapping QD cups for quick detach sling swivels. The QD cups and swivels are sold separately, along with an optional buttstock rail. Building Your Rifle The MBA-1 pairs well with a free-float handguard, a quality trigger and a magnified optic for a precision AR.
