MSTN 10.5″ 5.56mm PDW

This custom build is based off of the totally unique and 100% reliable Battle Arms PDW lower receiver with its ultra compact buffer and stock system. To this lower receiver I’ve added a LaRue MBT trigger with the light hammer spring, BAD steel push pins, V7 ultralite magazine release with BAD extended mag button, and a V7 short throw titanium ambi safety selector. The BAD ATG pistol grip has been chosen for this application, as well. The BAD 556-LW billet upper receiver hosts a Noveske 10.5″ HFCL barrel with fixed gas block.The feed ramps have been contoured and polished. An LMT proof round tested, MP-inspected bolt has been fitted to the barrel at the optimum headspace for this application. The bolt has been Ionbond DLC coated down to the gas rings. The Young Mfg forged, then centerless ground, then hard chromed bolt carrier plus all internal BCG parts have also been Ionbond DLC coated. You won’t find a better bolt carrier group anywhere, at any price. A Vltor/BCM ambi Gunfighter charging handle has been selected for this application. There’s a Surefire WarComp on the muzzle, and the forend is the Fortis Switch Rail in 9″, modified especially for use with the Battle Arms Development upper receiver.

The SBR will be delivered in a hard plastic case with internal foam padding. Add 3.5% for CC use.

We can also offer this SBR in .300 Blackout with a 6.5″ barrel. Please see the last few photos.
