So you've picked up a sweet AR-15-style rifle with the latest freefloat fore-end. The handguard is nice and clean, with attachment points throughout for whatever you'd like to add. You want to minimize the rail space without limiting future use. What can you do?
Fortunately, the folks at LongShot Manufacturing have just the thing. Whether you have a KeyMod system or the new M-LOK, the company makes a mind-boggling number of rail options. Whether it's a 3-slot section barely exceeding 1 1/2 inches long or a massive 40-slot section for a rifle-size handguard, KeyMod or M-LOK, LongShot has what you need.
Merits of the individual systems aside, the key advantage to either is that accessories can be added very rapidly. As the systems mature, more and more accessories are being developed for direct attachment; however most gun people have a number of accessories designed before said systems that are designed to be attached to a Picatinny rail. For those accessories, being able to attach exactly the length of rail needed precisely where you want it is invaluable.
MSRP: Prices vary from $19.50 (3-slot) to $74 (40-slot) and the price includes all hardware and shipping. For the rails shown, pricing is as follows: 13-slot rail, $35.50; 15-slot rail, $39; 30-slot rail, $67 and 33-slot rail, $69.
